Sewage treatment agent

Abstract

The invention belongs to the technical field of sewage treatment and particularly relates to a sewage treatment agent which is prepared from the following raw materials in parts by weight: 15-25 parts of polyferric chloride, 10-30 parts of starch acetate, 3-11 parts of tannin, 12-28 parts of rice straw, 5-20 parts of fly ash and 5-13 parts of lipase. With scientific and reasonable cooperation of the raw materials and under the synergistic effect of the components, the sewage treatment agent provided by the invention has a good flocculation effect, and realizes a remarkable effect of eliminating COD, soluble inorganic matters, organic pollutants, heavy metals and other harmful particulate matters in sewage; and the water quality completely reaches the discharge standard.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a sewage treatment agent. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. Among the water pollution caused by human production activities, the water pollution caused by industry is the most serious. Such as industrial wastewater, which contains many pollutants and complex components. Industrial wastewater is the most important cause of water pollution caused by industrial pollution. It accounts for the majority of pollutants emitted by industry. The pollutants contained in industrial wastewater vary widely depending on the type of factory. Even in the same factory, the quality and quantity o...

AI Technical Summary

Problems solved by technology

Some sewage seeps into the soil, causing soil pollution and affecting the growth of plants and microorganisms in the soil

Some sewage also has an unpleasant stench, polluting the air

Toxic and harmful substances in sewage will be ingested and absorbed by plants and remain in the body, and then reach the human body through the food chain, causing harm to the human body

While improving product quality and quality, it has also brought about increasingly serious environmental pollution problems, mainly manifested in: high concentration of organic pollutants in wastewater, stable structure, poor biochemical properties, conventional processes are difficult to achieve standard discharge, and the treatment cost is high. Energy saving and emission reduction bring great pressure
