Problems solved by technology

Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc., and more and more enters the daily life of ordinary people. With the development of economy, sewage treatment The problem is becoming more and more serious. For sewage treatment, it needs to go through multiple treatment processes, such as solid-liquid filtration separation, recovery and flow adjustment, etc. Among them, it is necessary to introduce sewage into the biochemical treatment tank, and the biochemical treatment tank will purify the sewage. The structure and function of the biochemical treatment pool in the prior art are single, and the purification effect of sewage is not ideal

Abstract

The invention relates to the field of sewage treatment, and discloses a sewage treatment system. The sewage first enters from the sewage pool, undergoes preliminary sedimentation and filtration in the sewage pool, and then infiltrates into the overflow pool from both sides of the sewage pool. The pool undergoes anaerobic treatment, and then overflows from the overflow pool to the sterilization pool. The sewage is sterilized in the sterilization pool, and then pumped from the sterilization pool to the sedimentation tank for final purification. The heat pump device cleans the sewage pool, The sewage in the overflow tank, the sterilization tank and the sedimentation tank absorbs heat and utilizes it. The water inlet device monitors the sewage in the sedimentation tank, and at the same time controls the water inflow of the sewage tank and the water out of the sedimentation tank, and controls the time of sewage treatment. The structure and function are reasonable, and the sewage The purification effect is ideal.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system. Background technique [0002] Sewage treatment: the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc., and more and more enters the daily life of ordinary people. With the development of economy, sewage treatment The problem is becoming more and more serious. For sewage treatment, it needs to go through multiple treatment processes, such as solid-liquid filtration separation, recovery and flow adjustment, etc. Among them, it is necessary to introduce sewage into the biochemical treatment tank, and the biochemical treatment tank will purify the sewage. The structure and function of the biochemical t...
