Domestic sewage treatment device based on drop-type biological filter tower unit

Abstract

The invention discloses a domestic sewage treatment device based on a drop-type biological filter tower unit, including an anaerobic regulating tank, an anoxic reaction tank, and a drop-type biological filter tower unit. The water inlet end of the anaerobic regulating tank is arranged with an inlet pipe, The anaerobic regulating tank and the anoxic reaction tank are connected through an artesian channel, and a lift pump is arranged in the anoxic reaction tank, and the drop-type biological filter unit is located above the anaerobic regulating tank and the anoxic reaction tank, which includes a high water level The water inlet of the high water level tank is connected to the lifting pump in the anoxic reaction tank through the water pipeline, and the water outlet of the high water level tank is connected to the top of the drop-type biological filter unit, and the bottom of the drop-type biological filter unit is arranged with perforations The water collection pipe and the drop-type biological filter tower unit are provided with biological filter materials. The device integrates sewage collection, filtration, and biochemical treatment processes. It can effectively remove suspended solids, organic matter, nitrogen, phosphorus and other pollution factors. It has the advantages of high structural integration and good water treatment effect.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a domestic sewage treatment device. Background technique [0002] my country is a country with a large population and a large agriculture. Most of the population in our country is distributed in the countryside. In recent years, with the rapid economic development of various townships and the improvement of people's living standards, domestic water consumption has gradually increased, and the discharge of domestic sewage has continued to increase, making surface water bodies unable to bear excessive loads, and environmental safety hazards and problems. getting worse. Excessive domestic sewage discharge exceeds the self-purification capacity of the water body, causing water pollution, which not only affects the quality of life of residents, but also affects the health of residents. [0003] In 2009, the Ministry of Housing and Urban-Rural Development pointed...

AI Technical Summary

Problems solved by technology

It can be inferred that the treatment rate of rural domestic sewage is lower, and rural sewage is basically discharged into rivers and lakes on the spot. Due to the large amount of organic matter and N and P elements in the sewage, the environmental capacity and ecological carrying capacity of the water bodies of rivers and lakes are overwhelmed. The ecological system has been severely damaged, and the problem of water pollution has become increasingly serious, which has caused large-scale algal blooms and algae blooms, resulting in deterioration of water quality, seriously affecting the ecological environment in rural areas, and posing a hazard to people's quality of life and health
