Abstract

The invention relates to the technical field of sewage treatment, in particular to a sewage sedimentation tank for urban sewage with accurate medicament dosage. Thesewage sedimentation tankcomprises a sewage sedimentation tank main body, a monitoring probe, a first servo motor, a second servo motor, a first water level sensor, a second water level sensor, a first water electromagnetic valve, a control panel and a second water electromagnetic valve, wherein a filtering mechanism is arranged in the middle of the sewage sedimentation tank main body. Sewage is put into the sewage sedimentation tank main body through the first water electromagnetic valve, whether impurities exist in the sewage or not is judged by adding a small amount of sedimentation agent at a time and monitoring whether sediments are generated or not, the sediments are cleaned when the sediments are generated, the sedimentation agent is added again until no sediments are generated when the sedimentation agent is added at the last time, and water in the sedimentation tank is discharged and then is put into the sewage for sedimentation, so that the sewage does not need to be detected manually, and the problem that a large quantity of sedimentation agent is wasted or impurities in the sewage cannot be cleaned up can be effectively avoided.

Description

Technical field

[0001] The present invention relates to the field of sewage treatment, in particular a sewage sedimentation tank having an accurate dosage of urban sewage. Background technique

[0002] Urban sewage treatment refers to the measures taken to change the sewage properties and make it a measures taken to the environmental waters. Urban sewage treatment is generally divided into three levels: primary treatment, system application of physical treatment method removes non-dissolved pollutants and parasites in sewage; secondary treatment, systemic treatment of various complicated organic matter oxidation in sewage For a simple substance; three-level treatment, a chemical precipitation method, biochemical method, physicochemical method, etc., to remove phosphorus, nitrogen, difficult organics in sewage, inorganic salts, etc., wherein the precipitating agent is added to the flocculant and The condense is precipitated to impurities in the sewage, wherein the flocculant is by...
