Problems solved by technology
Due to the small volume of rural sewage, if the industrial treatment process is followed, it will inevitably result in high energy consumption and high cost
If the domestic sewage is treated by the ecological process of river and lake water treatment, there will be problems such as occupying a large area, seasonal alternation not up to standard, wetland blockage, etc.

Abstract
The invention discloses a domestic sewage treatment system which comprises a septic tank, an anaerobic tank and an advanced treatment device. Sewage can be collected by the septic tank, bulk dirt canbe intercepted by the septic tank, the anaerobic tank is connected to the septic tank and is used for degrading pollutants, the advanced treatment device is connected to the anaerobic tank, the septictank comprises a primary filter chamber, a secondary filter chamber and a sewage collecting chamber, blocky substances can be filtered out by the primary filter chamber, sewage from the primary filter chamber can be received by the secondary filter chamber, the secondary filter chamber is used for filtering out large particles, and sewage from the secondary filter chamber can be received by the sewage collecting chamber. The domestic sewage treatment system has the advantages that the sewage is pretreated layer upon layer at first, then advanced treatment is further carried out on the sewage,and accordingly the pollutants in the sewage can be stably and efficiently removed by the aid of the domestic sewage treatment system.
Description
technical field [0001] The invention relates to the field of sewage treatment, in particular to a domestic sewage treatment system. Background technique [0002] The treatment of rural sewage has attracted more and more attention from all parties, and more and more problems have been exposed. Due to the small volume of rural sewage, if the industrial treatment process is followed, it will inevitably result in high energy consumption and high cost. If the domestic sewage is treated with the ecological process of river and lake water treatment, there will be problems such as occupying a large area, substandard seasonal alternation, and wetland blockage. [0003] The market needs a sewage treatment system that can perform advanced treatment after pretreatment of sewage layer by layer, so as to achieve the purpose of stably and efficiently removing pollutants in water and discharging them up to standard. The present invention solves such problems. Contents of the invention ...
