Sewage treatment system

Abstract

The invention relates to the field of sewage treatment and discloses a sewage treatment system. Sewage firstly enters from a sewage pool, and preliminary sedimentary filtration is performed in the sewage pool, and then the sewage is infiltrated into an overflow pool from both sides of the sewage pool. The sewage undergoes anaerobic treatment in the sewage pool and the overflow pool and overflows to a sterilization pool from the overflow pool, the sewage undergoes sterilization treatment in the sterilization pool and then is sucked into a settling pool for final purification from the sterilization pool, a heat pump device absorbs heat of the sewage in the sewage pool, the overflow pool, the sterilization pool and the settling pool and makes use of the heat, a water inlet device monitors thesewage in the settling pool, at the same time water inflow into the sewage pool and water outflow from the settling pool are controlled, the sewage treatment time is controlled, the structure and functions are reasonable, and a sewage 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...
