Warm Reminder from Runhe Environmental Protection Company

Attention to mattersterm

The materials commonly used for buried equipment includefiberglassCompared to carbon steel, when purchasing equipment, it is necessary to inquire with the supplier about the materials used. When the process and other conditions are the same, the price of different materials will vary greatly.

Everything should be based on facts. No matter how the supplier who provides you with the equipment introduces its superior performance, you should ask the supplier to provide previous successful cases and then send someone to inspect its on-site sewage treatment effect. Although it may delay some time, it is indeed crucial.

Agreed execution standards for water discharge

Many units fail to specify the standard for sewage treatment in the contract when purchasing buried sewage treatment equipment, which can lead to disputes in the future when environmental protection requirements are raised. Due to different levels of treatment, the cost of sewage treatment can vary greatly.

Compare and sign contracts before purchasing, and specify the payment process.

Choose several suppliers as references, and then compare their adopted processes, successful cases, prices, and other factors comprehensively.

Sign a formal contract and agree on the delivery, commissioning, and payment process before paying the deposit.

Note:Hospital sewage(0.5-5) The equipment does not have a primary sedimentation tank, and the sewage directly enters the contact oxidation tank. The contact oxidation tank is secondary, and the sludge from the secondary sedimentation tank flows automatically to the sludge tank. Sludge is digested anaerobically.
5Hospital sewageScope of Equipment Application
This device is suitable for the treatment of domestic organic wastewater in residential areas, hotels, nursing homes, schools, mines, factories, and similar industrial organic wastewater treatment.
VIHospital sewageEquipment Process Description
　　Hospital sewageThe design of the equipment is mainly for the treatment of domestic sewage and similar industrial organic sewage, and its main treatment method is to use the currently mature biochemical treatment technology——shengwuContact oxidation method, water quality parameters are calculated based on the design of general domestic sewage quality, with an average BOD5 of 200mg/l and an effluent BOD5 of 20mg/l. It consists of six parts: (1) primary sedimentation tank, (2) contact oxidation tank, (3) secondary sedimentation tank, (4) disinfection tank and disinfection device, (5) sludge tank, (6) fan room and fan. The following are discussed separately: (1) Primary sedimentation tank: The primary sedimentation tank of this equipment is a hard flow sedimentation tank, and the upward flow velocity of sewage in the sedimentation tank is 0.6-0.7 mm/s. The settled sludge is lifted to the sludge tank by air. (Note:Hospital sewage0.5-5m3/h without primary sedimentation tank)
(2) Contact oxidation tank: After initial sedimentation, the water flows automatically to the contact tank for biochemical treatment. The contact tank is divided into three stages, with a total residence time of more than 4 hours. The enhanced equipment can achieve a contact oxidation time of up to 6 hours. The packing material is a novel trapezoidal packing material, which is easy to film and does not block. The specific surface area of the packing material is 160m2/m3, and the gas water ratio of the contact tank is about 12:1. (Note:Hospital sewage0.5-5m3/h contact tank is a second level)
(3) Secondary sedimentation tank: The biochemical wastewater flows into the secondary sedimentation tank, which is a parallel operation of two vertical flow sedimentation tanks with an upward flow rate of 0.3-0.4 mm/s. The sludge is discharged by air to the sludge tank. (Note)Hospital sewage0.5-5m3/h sludge flows automatically into the sludge tank
(4) Disinfection pool and disinfection device: The disinfection pool is designed to last for 30 minutes according to the "TJ14-74" standard. If it is hospital sewage, the disinfection pool can increase the residence time to 1-1.5 hours. The disinfection method uses solid chlorine tablets for contact dissolution, and the disinfection pool and device can be continuously adjusted according to the size of the water output

Variable dosage to achieve the goal of adding more water and more chemicals, and adding less water and less chemicals. Other devices can be separately prepared if needed. (Note: If used for industrial wastewater, disinfection tanks and disinfection devices can be omitted)
(5) Sludge tank: All sludge from the primary and secondary sedimentation tanks is transported by air toHospital sewageAerobic digestion is carried out in the sludge tank, and the supernatant of the sludge tank is added to the contact oxidation tank for further treatment. After digestion, there is very little residual sludge, which is usually cleaned once every 1-2 years. The cleaning method can be to use a suction truck to reach into the bottom of the sludge tank through the inspection hole for suction and then transport it outside. (Hospital sewage0.5-5m3/h sludge is digested anaerobically
(6) Fan room, fan: equipmentHospital sewageThe fan room is located above the disinfection tank, and the inlet of the fan room adopts double-layer sound insulation. The inlet has a muffler and a fan filter, so there is no noise during operation. The fan adopts two L-shaped Roots blowers, which can automatically alternate operation. The operating life of a single fan is about 30000 hours.

9Hospital sewageEquipment structure and characteristics
　　Hospital sewageDue to its underground installation, maintenance and upkeep of the equipment are relatively difficult. Therefore, in the design, the equipment has been considered to be maintenance free, with a reasonable and reliable overall structure. At the same time, it has also been taken into account that even in the event of some malfunctions, the equipment can be accessed through its various inspection holes.
　　Hospital sewageAll facilities of the equipment are located in several boxes, which are made of A3 steel plates with a thickness of 8mm. The boxes are connected by seamless steel pipes, and both the inside and outside of the equipment are coated with chlorosulfonated polyethylene anti-corrosion coating promoted by the Ministry of Chemical Industry. The equipment is generally coated with 8 layers of this coating: 2 layers of primer and 6 layers of topcoat. The anti-corrosion service life can generally reach more than 10 years.
