Description
Technical Field
The invention relates to the field of sewage treatment, in particular to a sewage green environment-friendly treating agent.
Background
The discharge of sewage causes serious pollution to the environment, and some sewage discharges not only pollute ground water, but also pollute underground water sources, and even influence the life and life safety of people. China is one of 13 countries which are the most poor water in the world at present, and along with the increasing severity of water eutrophication, the water quality condition of China is worried. According to the report of 'Chinese environmental performance assessment' newly published by economic cooperation and development organization, more than 75% of water flowing through China city is not suitable for drinking at present, and more than 30% of detected river water quality belongs to the inferior V class. Along with the development of industry, the pollution degree of urban drinking water sources is increasingly intensified, and along with the improvement of living standard, the requirements of people on drinking water quality and drinking water quality standards are more and more strict.
Patent CN201310328285.7 discloses a wastewater treatment agent, which is simple and convenient, but the main water purification agent used in the wastewater treatment agent mainly comprises a ferrosilicon copolymer and a fenton reagent, the ferrosilicon copolymer is formed by polymerizing sodium silicate and ferrate, the fenton reagent is obtained by reacting hydrogen peroxide and ferrous sulfate, and the greatest disadvantage of the wastewater treatment agent is that:
(a) the existing sewage treatment agent is mostly developed according to specific industries, for example, the treatment agent for treating printing and dyeing wastewater is not suitable for treating wastewater of a pesticide factory, and the treatment agent disclosed above is more suitable for treating sewage with COD, high ammonia nitrogen content, turbidity, chromaticity, conductivity, odor, pH value, total hardness and chloride close to common water quality.
(b) Most of corrosion inhibitors and flocculating agents used by the existing sewage treatment agents are non-environment-friendly products, and waste residues generated by using a large amount of the corrosion inhibitors and the flocculating agents are difficult to degrade and can cause secondary pollution to the environment.
(c) The price of the existing sewage treatment agent is generally higher, which hinders the development of the environmental protection career of China.
Patent CN201110187438.1 discloses a paint wastewater treatment agent, which adopts environment-friendly water treatment reagents, namely sodium lignosulfonate aqueous solution, chitosan aqueous solution and polyacrylamide aqueous solution, but practice shows that the paint wastewater treatment agent only has certain effect on treating paint wastewater, when the paint wastewater treatment agent is used for treating wastewater of other sewage plants, the treatment effect is greatly reduced, and the using amount of the treatment agent is greatly increased.
Disclosure of Invention
The invention aims to solve the technical problem of providing a treating agent which has high adsorption capacity, stable adsorption on heavy metals, no secondary pollution, high speed, good adsorption, flocculation and sedimentation effects, thorough treatment, stable treatment effect, environmental protection and no toxicity, and can reach the discharge standard.
