scope of application

The treatment of domestic sewage in residential areas, hospitals, schools, villa communities, hotels, nursing homes, and other places. The treatment of production wastewater from aquatic processing plants, livestock processing plants, fresh milk processing plants, and garbage transfer stations.

Product Features

1. The RC-AO series sewage treatment equipment can be placed above the ground or buried below the surface. The surface can be used as green or square land, so the equipment does not occupy surface area, does not require building, and does not require heating and insulation.

2. The RC-AO series sewage treatment consists of secondary tanks, with the first stage being a reinforced concrete structure with a relatively deep burial depth, and the other group being a steel structure with a relatively shallow burial depth. The steel structure pool adopts the domestic * interpenetrating network anti-corrosion coating for anti-corrosion. It is an interpenetrating polymer formed by the interpenetrating of a rubber network and a plastic network. It is resistant to acid, alkali, salt, gasoline, kerosene, aging, abrasion, and rust. After applying the coating, the anti-corrosion life of the equipment can generally reach more than 30 years.

3. The AO biological treatment process in the RC-AO series sewage treatment equipment adopts a push flow biological contact oxidation tank, which has better treatment than mixed or two-stage series mixed biological contact oxidation tanks. And it has a smaller volume than activated sludge tanks, strong adaptability to water quality, good impact resistance, stable effluent quality, and will not cause sludge expansion. At the same time, a new type of elastic three-dimensional packing material was used in the biological contact oxidation tank, which has a large actual specific surface area and is convenient for microbial biofilm formation and detachment. Under the same organic load conditions, it has a higher removal rate of organic matter than other packing materials and can improve the solubility of oxygen in water.

4. Due to the use of a biological contact oxidation tank in the AO biological treatment process, the volume load of the packing is relatively low, and the microorganisms are in the self oxidation stage, resulting in less sludge production. In addition, the moisture content of the sludge produced by the biological contact oxidation tank is much lower than that of the sludge produced by the activated sludge tank. Therefore, the amount of sludge generated by the RC-AO series sewage treatment equipment is relatively small, and generally only needs to be discharged once every 90 days.

5. The RC-AO series sewage treatment equipment not only adopts conventional blower noise reduction measures (such as vibration isolation pads, mufflers, etc.), but also sets up new sound-absorbing materials on the inner wall of the blower room, so that the noise level during equipment operation is below 50 decibels, reducing the impact on the surrounding environment.

6. The RC-AO series sewage treatment equipment is equipped with soil deodorization facilities. It utilizes reinforced concrete structure to set up improved soil and air distribution pipes in the upper space of the pool body. When the odorous components dissolve in the water contained in the soil through the soil layer, they are then transferred into the soil due to surface adsorption and chemical reactions, and finally decomposed by microorganisms to achieve deodorization.

7. The RC-AO series sewage treatment equipment is equipped with a fully automatic electrical control system, which has good reliability. Therefore, there is no need for dedicated personnel to manage it, only monthly and quarterly maintenance and upkeep are required.

Technical Parameter

The removal of organic pollutants and ammonia nitrogen by RC-AO series sewage treatment equipment mainly relies on the AO biological treatment process in the equipment. The working principle is that due to the high concentration of organic matter in sewage, microorganisms are in a state of gas deficiency. At this time, microorganisms are facultative microorganisms, which convert and decompose organic ammonia in sewage into NH3-N. At the same time, they use organic carbon as an electron donor to convert NO-2-N and NO-3-N into N2, and also use some organic carbon sources and NH3-N to synthesize new cellular substances. So the tank not only has a certain function of removing organic matter, reducing the organic load of subsequent aerobic tanks to facilitate nitrification, but also relies on the high concentration of organic matter in the raw water to complete denitrification and ultimately eliminate nitrogen eutrophication pollution. At level O, although the concentration of organic matter has significantly decreased, there is still a certain amount of organic matter and high NH3-N present. In order to further oxidize and decompose organic matter, and ensure smooth nitrification while carbonization is complete, an aerobic biological contact oxidation tank with low organic load is set up at level O. In the O-level pool, aerobic microorganisms and aerobic bacteria (nitrifying bacteria) are mainly present. Aerobic microorganisms decompose organic matter into CO2 and H2O; Autotrophic bacteria (nitrifying bacteria) use inorganic carbon produced by the decomposition of organic matter or CO2 in the air as a nutrient source to convert NH3-N in wastewater into N-2-ON, N-3-ON, and the effluent from O-grade tanks is returned to the * tank, providing electron acceptors for the * tank and ultimately eliminating nitrogen pollution through denitrification.

Equipment installation, debugging, and maintenance

1. Installation: This equipment consists of two sets of tanks, one set is a reinforced concrete structure tank body, and the other set is a steel structure tank body. The reinforced concrete pool body is buried underground, and the steel structure pool body can be buried below the floor or installed on the floor. The civil engineering condition drawings for two sets of pool foundations are provided by our company, and it is required that the excavation width around the perimeter should be at least 600mm larger than the equipment plan size.

2. According to the installation diagram, use a crane to lift the steel structure pool into place. The installation must be carried out under the guidance of our technical personnel, and the position and direction of the box cannot be placed incorrectly. Our company is responsible for the pipeline connection between the pools.

3. After installation, the equipment must be filled with water and tested for leaks at all pipeline interfaces before soil can be filled around and in the gaps of the equipment, and the ground should be leveled. The control lines of the electrical control cabinet should be connected to the equipment, and the electrical control cabinet should be connected to the power lines. Pay attention to the direction of the fan and water pump when wiring.

4. After the installation of the equipment, it is necessary to ensure that there is no water accumulation on the rainy ground, and no heavy objects should be placed above the steel structure pool. Equipment generally does not evacuate internal sewage to prevent groundwater from floating the equipment.

5. Debugging: Our company is responsible for the debugging work. In order to speed up the debugging progress, bacterial strains can be added. To avoid bacterial loss, the water inflow can be reduced and the fan can be started for aeration until a layer of orange yellow biofilm grows on the packing, which is the completion of packing film hanging. Then, the water inflow can be increased to the rated flow rate. After completing the membrane coating of the packing material, the microorganisms in the biological tank are acclimated by gradually reducing the amount of aerator, so that the biological tank is in a state of hypoxia and the microorganisms on the packing material become facultative microorganisms. Then adaptively operate the microorganisms until they meet the design requirements.

6. Equipment maintenance and upkeep: Our company has established a regular maintenance system for AO series sewage treatment equipment for customers, with the main vulnerable component being the water pump. Regularly check the looseness of screws in various parts of the fan and water pump, the tightness of the packing box, the temperature of the bearings, and the quality and amount of lubricating oil to ensure that all parts are normal. At the same time, check the dosage and remaining amount of disinfectant, and adjust the dosage and supplement disinfectant if necessary. The fan and water pump should be maintained and repaired every 5000-8000 hours of operation.

The Bohai region is a gathering area for heavy industry in China. It is also a densely populated area, therefore, the discharge of industrial wastewater and domestic sewage has been consistently high. In recent years, with the improvement of port construction, increased throughput, and increasingly severe pollution caused by ship transportation. The natural disadvantage of water purification combined with unreasonable utilization methods has led to frequent occurrences of eutrophication, frequent red tide outbreaks, and water quality deterioration affecting biodiversity in the Bohai Sea.

At the end of November 2018, in order to improve the ecological environment quality of the Bohai Sea and adhere to the coordinated planning of land and sea, the Ministry of Ecology and Environment, the National Development and Reform Commission, and the Ministry of Natural Resources issued the "Action Plan for Comprehensive Governance of the Bohai Sea", focusing on comprehensive governance of the Bohai Sea from multiple aspects such as river pollution entering the sea, direct discharge of marine pollution sources, ship pollution control, port pollution control, and prevention and control of marine garbage pollution.
