1. Analysis of rural sewage water quality:
Rural domestic sewage is characterized by large volume, concentrated drainage, high COD concentration, and a large amount of impurities and suspended solids. On the one hand, untreated domestic sewage flows into surface water bodies such as low-lying rivers, lakes, and ponds, seriously polluting various water sources. On the other hand, domestic sewage is also the source of disease transmission and spread, easily causing the occurrence and prevalence of infectious diseases, endemic diseases, and zoonotic diseases in some areas. The random discharge of domestic sewage seriously pollutes the rural ecological environment and directly threatens the health of the vast number of farmers and the economic development of rural areas.
2. Process of rural sewage treatment equipment
The basic structure of the rural sewage treatment equipment produced by Shandong Zetray Environmental Protection Technology Co., Ltd.: The shell materials include carbon steel anti-corrosion and fiberglass. All pipes are made of PVC pipes or stainless steel pipes, and the connections between pipes are bonded with PVC adhesive or welded with stainless steel. The filler uses suspended biological fillers as the biological carrier, which has a large biomass, is easy to form biofilm, does not form balls, and is not blocked.
When the rural sewage treatment equipment treats sewage, domestic sewage flows into the aeration area from the top of the device. The aerator aerates underwater and stirs the sewage by pushing the flow. The incoming sewage quickly mixes fully with the original mixed liquid, adapting to the changes in the influent water quality to the greatest extent. The aerator has the dual functions of water flow propulsion and underwater aeration, making the sewage in the aeration area circulate regularly and increasing the dissolved oxygen content in the sewage in the integrated sewage treatment equipment. The aerator has the dual functions of water flow propulsion and underwater aeration, making the sewage in the aeration area circulate regularly and increasing the dissolved oxygen content in the sewage. Since the sewage circulates continuously in the aeration area, the water quality at each point in the area is relatively uniform, and the quantity and nature of microorganisms are basically the same. Therefore, the working conditions of each part in the aeration area are almost the same. This controls the entire biochemical reaction under good and the same conditions; organic matter is gradually degraded by microorganisms, and the sewage is purified.

3. Advantages of rural sewage treatment equipment
1. The rural sewage treatment equipment is assembled on-site. It is light in weight, easy to transport and convenient to install.
2. The rural sewage treatment equipment uses anti-corrosion components made of fiberglass, carbon steel and stainless steel, which have excellent characteristics such as corrosion resistance and aging resistance, and have a long service life.
3. It can be placed below the ground surface. The ground above the equipment can be used for greening or other purposes, without the need for building houses, heating and insulation. It maximizes the integration of the system and reduces the floor area. (It can also be placed above the ground surface.)
4. It causes no pollution, no noise and no odor, reducing secondary pollution.
5. It is not limited by the volume of domestic sewage, being flexible. It can be used alone or in combination with multiple units.
6. The whole rural sewage treatment equipment system is equipped with a PLC fully automatic electrical control system and an equipment fault alarm system. It operates safely and reliably. Generally, no special personnel are needed for management on a daily basis. Only timely maintenance of the equipment is required, and the management cost is low.
