Background
With the development of society, the great discharge of industrial sewage and urban wastewater brings great challenges to the environment. The waste water generated in different environments has great differences in ammonia nitrogen, COD content, PH value and conductivity, so that the waste water treatment agent and the water treatment method suitable for multiple industries are difficult to obtain. The water treatment agent can be divided into two types, namely, chemicals with definite molecular structural formulas and compound names, which are part of fine chemicals; the other is a water treatment agent compound formula product (hereinafter referred to as a 'compound product'), which has no definite molecular structural formula and compound name and is named by the characteristics of the application and the performance (usually called as a brand). One often refers to the first class of products as specialty water treatment agents and the second class of products as specialty water treatment agents. The water treatment agent plays a significant role in the water treatment process. The existing water treatment products mainly comprise series products such as scale inhibitors, corrosion inhibitors, bactericides, cleaning agents, pre-filming agents, chelating agents, dispersing agents and the like which are produced, and a plurality of products are often matched for use to ensure that sewage can be well treated.
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 has a certain effect only 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, the using amount of the treatment agent is greatly increased, and the invention develops a wastewater treatment agent with wide application range, good effect and low price, and the treatment method is greatly simplified.
