Abstract

The invention discloses an urban sewage treatment agent and a sewage treatment technology. The urban sewage treatment agent comprises the following raw materials: polyaluminum chloride, polyferric sulfate, sodium silicate, active carbon, zeolite powder, an antifoaming agent, a surfactant and water. The urban sewage treatment agent of the invention has wide sources of the raw materials. Active carbon has a strong adsorption effect and can effectively adsorb inorganic salt in a water body. polyaluminum chloride and polyferric sulfate have a strong flocculation effect, and can significantly reduce suspended solids and small granules in sewage. The preparation technology is simple, and the application method is simple. The urban sewage treatment agent has good adsorption, flocculation and precipitation effects, has high sewage treatment efficiency, and is a comprehensive sewage treatment medicament with very stable performance. The sewage treatment technology is simple and efficient, has an excellent removal effect on total nitrogen, total phosphorus, ammonia nitrogen, COD, BOD and SS in water, and will not cause secondary pollution.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an urban domestic sewage treatment agent and a sewage treatment process. Background technique [0002] Sewage usually refers to the waste water discharged from life and production that is polluted to a certain extent. The main pollutants contained in sewage include organic pollutants, oxygen-consuming pollutants, anaerobic pollutants, plant pollutants, toxic pollutants, and radioactive pollutants. ,wait. [0003] Domestic sewage is mainly the discharge water produced by various kitchen water, washing water and toilet water used in human life, and most of them are non-toxic inorganic salts. Sewage produced in the process of human life is one of the main sources of water pollution. Mainly feces and washing sewage. The amount of domestic sewage discharged by each person in the city is 150-400L per day, which is closely related to the living standard. Domestic sewage con...
