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 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, which can easily lead to 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 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. 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 sewageFlow into the aeration zone from the top of the device. The aerator aerates underwater and pushes the flow to stir the sewage. The incoming sewage is quickly and fully mixed with the original mixed liquid, adapting to the changes in the influent water quality to the greatest extent. The aerator, through the dual functions of water flow propulsion and underwater aeration, makes the sewage in the aeration zone circulate regularly, increasing the dissolved oxygen content in the sewage. The integrated sewage treatment equipment. The aerator, through the dual functions of water flow propulsion and underwater aeration, makes the sewage in the aeration zone circulate regularly, increasing the dissolved oxygen content in the sewage. Since the sewage circulates continuously in the aeration zone, the water quality at each point in the zone is relatively uniform, and the quantity and properties of microorganisms are basically the same. Therefore, the working conditions of each part of the aeration zone are almost the same. This controls the entire biochemical reaction under the same good conditions; the 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 lightweight, 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 anti - aging, and has a long service life.
3. It is 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 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 is pollution - free, noiseless and odorless, reducing secondary pollution;
5. It is not restricted by the volume of domestic sewage, being flexible. It can be used individually or in combination with multiple units.
6. The whole set of 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 on a daily basis. Only timely maintenance of the equipment is needed, and the management cost is low.
