Description

Municipal sewage has accurate sewage sedimentation tank of medicament quantity

Technical Field

The invention relates to the technical field of sewage treatment, in particular to a sewage sedimentation tank with accurate medicament dosage for urban sewage.

Background

Municipal sewage treatment refers to measures taken to change the nature of sewage so that the sewage does not harm the environmental waters. The urban sewage treatment is generally divided into three stages: first-stage treatment, namely removing insoluble pollutants and parasitic ova in the sewage by using a physical treatment method; the second-stage treatment is to apply a biological treatment method to oxidize and degrade various complex organic matters in the sewage into simple substances; three-stage treatment, which is to remove phosphorus, nitrogen, organic matters and inorganic salts which are difficult to degrade in the sewage by applying a chemical precipitation method, a biochemical method, a physical-chemical method and the like, wherein, the impurities in the sewage are precipitated by adding a flocculating agent and a coagulant in the precipitation method, wherein, the flocculating agent uses Polyacrylamide (PAM) which is a water-soluble linear high molecular polymer formed by polymerization of Acrylamide (AM) monomer through free radical initiation and has good flocculation property, the polyacrylamide can be dissolved in water in any proportion, the aqueous solution is uniform and transparent liquid, the coagulant is usually polyaluminium chloride (PAC), and the polyaluminium chloride has the advantages of good spray drying stability, wide applicable water range, high hydrolysis speed, strong adsorption capacity, large formed alumen ustum, high density and precipitation speed, low effluent turbidity, good dehydration performance and the like.

Because the impurity content in the sewage in different areas and different time periods of the urban sewage is different, the dosage of the precipitating medicament can not be accurately controlled in the process of precipitating the impurities in the urban sewage, the traditional sewage sedimentation tank generally only carries out once precipitation, and quantitative precipitating medicament is added in each precipitation, may be excessive or may be small, especially in the case of low or high impurity content in the waste water, thereby causing the problems of waste of the precipitating agent or insufficient precipitation of the impurities in the sewage, the proper amount of the precipitating agent is usually added to manually detect and judge the content of the impurities in the sewage, however, the content of impurities in the sewage needs to be frequently detected by manual detection, a great deal of time is consumed, therefore, the speed of sewage sedimentation treatment is reduced, and a sewage sedimentation tank with accurate dosage of the medicament for urban sewage is needed to solve the problems.
