How to properly select the domestic sewage treatment equipment in the village?
Compared with urban sewage, domestic sewage in villages and towns has the characteristics of wide dispersion, relatively small amount of water, large variation of water quality and daily variation, and large seasonal differences. The design of domestic sewage treatment facilities in villages and towns refers to the current national norms or guidelines. Due to a series of reasons such as safety and development, the design is often too large. It is often the case that the treated water volume only accounts for a small proportion of the design scale, or the actual treatment water quality is low. The overall design is too large. However, the large design often leads to high idle rate of sewage treatment facilities in actual operation, and serious waste of investment operation, which is inconsistent with the relatively backward economic development of villages and towns. Bet Environmental has analyzed the design problems of some domestic sewage treatment in villages and towns, and put forward corresponding countermeasures for reference by relevant designers.
Bate Environmental Protection puts forward the following suggestions for the problem of large design of domestic sewage treatment in villages and towns:
1. Design of domestic sewage treatment equipment in villages and towns
First, for the design scale and design water quality, field research should be carried out as far as possible; for the process of urbanization in China, the construction of sewage treatment in villages and towns should give priority to the construction of near-and long-term phases.
Second: the location of the village sewage treatment plant is easy to approach. Try to avoid the problem of contaminant deposition caused by long-distance water delivery.
Third: For the low-concentration water inflow, the village and town sewage treatment process should choose a biofilm process with better adaptability to low-concentration wastewater treatment.
Fourth: key equipment for sewage treatment, such as pumps and fans, easy to set up the inverter. When the actual processing flow is low, the flow is adjusted by adjusting the motor speed to reduce the power. The equipment of the anti-specific system has been in waste in the inefficient area for a long time.
2. Operation of sewage treatment equipment in villages and towns
The village and town sewage treatment projects have been built to avoid low-load operation. The sludge load should be adjusted according to the actual water inflow during operation.
