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 easily causes 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 is made of carbon steel anti - corrosion material, fiberglass, etc. 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 clogged.
When the domestic 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 is quickly and fully mixed with the original mixed liquid, adapting to the changes in the influent water quality to the maximum 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. The integrated sewage 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. Due to the continuous circulation of sewage in the aeration area, the water quality at each point in the area
Relatively uniform, the quantity and properties of microorganisms are basically the same. Therefore, the working conditions of each part in the aeration zone 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. Since the sewage continuously circulates 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 in the aeration zone are almost the same; this controls the entire biochemical reaction under the same good conditions, and organic matter is gradually degraded by microorganisms, and the sewage is purified. (Discharge Standard of Pollutants for Sewage Treatment Plants in Rural Areas, Water Quality Standard for Urban Wastewater Reuse for Landscape and Environment (GB/T 18921—2002 Reuse Standard))III. Advantages of Domestic Sewage Treatment Equipment in Rural Areas
1. It is assembled and combined 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, 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 surface above the equipment can be used for greening or other purposes, without the need for building houses, heating and heat preservation. It maximally realizes the integration of the system and reduces the floor area; (it can also be placed on the ground surface)
4. It is pollution - free, noiseless and odorless, reducing secondary pollution;
5. It is not affected by domestic sewageLimited by water volume, it is flexible and can be used individually or in combination.
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 dedicated person is needed for management on a daily basis. Only timely maintenance of the equipment is required, and the management cost is low.
