1.Analysis of the water quality of rural domestic sewage:
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 freely 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, directly threatening the health of the vast number of farmers and the economic development of rural areas.
2. Process of rural domestic sewage treatment equipment
The basic structure of the domestic 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 filler as the biological carrier, which has a large biomass, is easy to form biofilm, does not form balls, and is not blocked.
When the domestic sewage treatment equipment treats sewage, domestic sewage flows into the aerationIn the aeration area, the aerator aerates underwater and pushes the flow to stir the sewage. The incoming sewage quickly mixes thoroughly with the original mixed liquid, adapting to the changes in the influent water quality to the greatest extent. Through the dual functions of water flow propulsion and underwater aeration, the aerator makes the sewage in the aeration area circulate regularly, increasing the dissolved oxygen content in the sewage. This is an integrated sewage treatment equipment. Through the dual functions of water flow propulsion and underwater aeration, the aerator makes the sewage in the aeration area circulate regularly, 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 properties of microorganisms are basically the same. Therefore, the working conditions of each part of the aeration area are almost the same. This controls the entire biochemical reaction under the same good conditions; organic matter is gradually degraded by microorganisms, and the sewage is purified.

III. Advantages of Rural Domestic Sewage Treatment Equipment
1. It is assembled on - site. It is light in weight, easy to transport, and convenient to install;
2. It uses anti - corrosion components made of fiberglass, carbon steel, and stainless steel, with excellent characteristics such as corrosion resistance and aging resistance, and has a long service life.
3. It can be placed below the ground surface. The ground surface above the equipment can be used for greening or other purposes, without the need for building houses, heating, or insulation. It maximally realizes the integration of the system and reduces the floor area; (It can also be placed on 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 individually or in combination with multiple units.
6. The entire equipment treatment system is equipped with a PLC fully automatic electrical control system and an equipment fault alarm system. It operates safely and reliably. Generally, no full - time personnel are required for management. Only timely maintenance of the equipment is needed, and the management cost is low.
