Abstract

The invention discloses an efficient urban sewage treating agent. The treating agent is prepared from the following raw materials of, by weight, 3-5 parts of polyacrylamide, 5-10 parts of alkyl alcohol amide, 2-6 parts of coconut oil, 5-10 parts of ferric chloride, 5-8 parts of clay, 2-5 parts of diatomite, 0.1-0.5 part of disodium ethylenediamine tetraacetate, 1-3 parts of fly ash, 2-8 parts of calcium hypophosphite, 2-5 parts of radix sophorae flavescentis and 2-7 parts of methyl 2-hydroxyisobutyrate. According to the sewage treating agent, by compounding the raw materials, the coordinating function is brought into play, the content of COD, BOD, SS and the like in urban sewage can be effectively reduced, and treated water can be recycled repeatedly. The sewage treating process is simple, and use is convenient. Moreover, the production cost is lower, the sewage treating period is short, and the urban sewage treating effect is better. Meanwhile, the influence of the raw materials on operators is avoided, the influence on the environment is avoided even if a large number of the treating agents are used, and the treating agent is more environmentally friendly.

Description

technical field [0001] The invention relates to a sewage treatment agent, in particular to an efficient urban domestic sewage treatment agent. Background technique [0002] The development and progress of my country's sewage treatment industry is relatively late. Since the founding of the People's Republic of China and before the reform and opening up, the demand for my country's sewage treatment is mainly for industrial and national defense cutting-edge applications. After the reform and opening up, the rapid development of the national economy and the significant improvement of people's living standards have stimulated the demand for sewage treatment. After entering the 1990s, my country's sewage treatment industry entered a period of rapid development, and the growth rate of sewage treatment demand was much higher than the global level. On the whole, my country's sewage treatment is undergoing a profound transformation from small scale, low level, single variety, serious...
