1、 Current situation of rural sewage

The main discharge routes for rural domestic sewage in China are direct sprinkling onto the ground, nearby discharge into rivers, or entering rivers through sewers. The main problems in rural sewage discharge are as follows: firstly, many farmers have built triple format septic tanks during the renovation of sanitation facilities in new and old houses, but they do not have discharge facilities and rely on soil infiltration. Although this method is simple, it seriously pollutes the surrounding groundwater; Secondly, even if there is a drainage system, the vast majority of them are combined sewer drainage, and generally open ditch drainage is used. Due to the lack of scientific and reasonable planning, coupled with the extensive use of pesticides and the influx of livestock manure into ditches with rainwater, the odor is unpleasant on sunny days, seriously polluting the rural living environment; Thirdly, rural areas often have irrigation channels running through them. With the widespread use of flush toilets by households, a large amount of untreated sewage and wastewater are discharged into irrigation channels, causing significant pollution to agricultural irrigation water.

3、 Common troubleshooting methods

1. Abnormal effluent: Check if the connecting pipes of the contact oxidation tank, sedimentation tank, disinfection tank, and sludge tank are blocked (usually caused by detached biofilm and damaged elastic three-dimensional packing).

2. Uneven aeration in the contact oxidation tank: Check if the outlet valve of the aeration fan is in the normal position and if the aeration head is damaged. 3. The contact effect of biofilm is not obvious. A. Check whether the aeration in the contact oxidation tank is uniform and whether the sludge in the secondary sedimentation tank is pumped to the tank; B、 If the above situation is normal, add an appropriate amount of nutrients (such as white sugar, urea, etc.) to the pool.

4. The effluent quality does not meet the standard A, and the inflow is too large; B、 Uneven aeration or prolonged shutdown of the contact oxidation tank (in which case the biofilm must be re cultured); C、 Excessive sludge in the sedimentation tank (sludge must be removed); D、 The disinfection device is shut down and the effluent is not disinfected for a long time.

5. Automatic control malfunction A, check if the power supply of the automatic control cabinet is normal; B、 Check if the supporting lifting pump and aeration fan are damaged (at this time, excessive current may cause the short-circuit switch to automatically disconnect).
