Price of washing wastewater treatment equipment——Application example:
1.Domestic sewage and hospital sewage from residential areas, highway service areas, government institutions, hotels and restaurants
2.Comprehensive municipal sewage in the development zone
3.Low concentration easily degradable organic industrial wastewater from food processing, brewing, and livestock slaughter
Price of washing wastewater treatment equipment——Equipment process advantages
1The ideal push flow process increases the driving force of biochemical reactions, improves efficiency, and alternates between anaerobic and aerobic conditions in the tank, resulting in good purification effects.
2Stable operation effect and sedimentation of sewage in ideal static state require short time, high efficiency, and good effluent quality.
3Resistant to impact loads, with retained treated water in the pool, capable of diluting and buffering wastewater, effectively resisting the impact of water volume and organic pollutants.
4Each process in the manufacturing process can be adjusted and operated flexibly according to water quality and quantity.
5Less processing equipment, simple structure, easy to operate and maintain management.
6There is a presence in the reaction tankDO、BOD5The concentration gradient effectively controls the expansion of activated sludge.
7The system itself is also suitable for the combination construction method, which is beneficial for the expansion and renovation of wastewater treatment plants.
8Properly controlling the operation mode of denitrification and phosphorus removal can achieve good denitrification and phosphorus removal effects by alternating between aerobic, anoxic, and anaerobic states.
Price of washing wastewater treatment equipment——Cultivation of biofilm
1Sewage enters the equipment;
2Start the fan and reduce the oxygen filling of the sludge pump and fan to about half of the normal oxygen filling;
3Observe the packing situation in the aerobic tank every day. If there is a sticky layer of orange yellow or orange black on the packing, it indicates that the biofilm has been cultured. The cultivation interval is generally10 - 25Day completed;
4The temperature is generally in Celsius15℃- 25℃ is suitable;
5If the concentration of the original sewage is too low and the cultivation time of the biofilm is too long, it is necessary to add some nutrients, mainly feces or other substances, if necessary;
6、PHThe value must be guaranteed to be within6.5 - 8.5Between them, the original sewage should be ensured to reach a biodegradable state;
7Before starting the commissioning of underground sewage treatment equipment for treating industrial and hospital sewage, domestic sewage should be the main source. After the biofilm is cultivated, a small amount of other industrial sewage should be continuously introduced to adapt to the growth of industrial sewage, and the commissioning should start normally
Price of washing wastewater treatment equipment——Construction of civil engineering technology for foundation pit of buried domestic sewage treatment equipment:
The first step is to slope the foundation pit according to the size of the buried sewage treatment equipment model. The slope size depends on the soil conditions and the thickness of the covering soil above the top of the product. The slope angle is30°-50°.
The depth of the second excavation trench and the elevation of the inlet and outlet connected to the sewage pipeline should reserve the bottom of the trench when calculating the elevation200mmSand laying size;The excavated soil pile is placed around the trench pit5To prevent landslides caused by lateral soil pressure beyond meters, and to reserve a work site for the lifting of domestic sewage treatment equipment.
When encountering groundwater, the third buried domestic sewage treatment equipment should first remove the groundwater, carry out foundation treatment according to the size and requirements of the schematic diagram, compact the base layer, and then lay sand. sanding200mmAnd level it, no sharp corners, stones or other debris are allowed in the sand.
When there is no groundwater in the fourth buried domestic sewage treatment equipment, the foundation should be compacted, sandblasted, and treated according to the schematic diagram and requirements.
In areas with high groundwater levels, the fifth buried domestic sewage treatment equipment can be excavated with increased precipitation or open precipitation. When using open precipitation to dig trenches, preparation work must be done before construction.
Price of washing wastewater treatment equipment——Safety precautions
1All personnel participating in the clean water debugging must wear safety helmets.
2Check if the power lines connecting the devices are connected correctly.
3Determine the high load of the underground integrated sewage treatment equipment linkage equipment to ensure normal commissioning.
4Protective measures such as insulated gloves for commissioning and operating personnel of buried integrated sewage treatment equipment.
5During the commissioning period of the buried integrated sewage treatment equipment, there should be a dedicated person to guard it.
6The upper edge of the foundation pit1mIt is not allowed to pile up soil, materials, or park machinery within the scope.
7Construction personnel outside the foundation pit are not allowed to throw debris into the pit. When passing tools under the foundation pit, they must be firmly secured before releasing them.
8Personnel underground should rest away from the edge of the foundation pit and the slope to prevent carelessness.
9All construction machinery must obey the command of the commanding personnel, and personnel should try to stay away from the construction machinery as much as possible. If necessary, notify the operators first and wait for a response before approaching
Price of washing wastewater treatment equipment——The operation of the blower should pay attention to the following key points:
1The daily management of the blower is very important, and the operator should regularly check whether the air pressure at the inlet and outlet of the blower is normal. The inlet air pressure is low.
2Firstly, consider cleaning and replacing the filter. The export wind pressure is high, and it is necessary to check whether the impeller of the air outlet pipeline and aeration head is blocked by water accumulation, and deal with the symptoms to ensure normal operation.
3Whether the ventilation in the fan room of the buried sewage treatment equipment is good: During the operation of the blower, it consumes a lot of electricity and energy, and can generate a large amount of heat. This heat should be diffused in a timely manner to avoid the blower temperature being too high, which can directly lead to the service life of the motor and cause insufficient power of the blower, ultimately stopping the operation of the blower and affecting the survival rate of activated sludge, leading to the failure of sewage treatment equipment treatment. In the later stage, when the excess sludge is filtered by the sludge concentration dewatering machine, the sludge flocculation degree is also poor. Increasing processing difficulty.
4The summer management of the blower is also very important. The high temperature in summer leads to an increase in the temperature of the blower, and the high exhaust temperature affects the amount of oxygen charged.
5Maintenance and lubrication work. In the daily operation of buried sewage treatment equipment, the operator shall assign dedicated personnel for lubrication and maintenance, and refuel according to regulations.
