Abstract

The invention relates to a sewage treating solvent. The sewage treating solvent is prepared from, by weight, 10-30 parts of diszolidinyl urea, 5-15 parts of methylisothiazolinone, 10-15 parts of medical stone particles, 20-30 parts of sodium lignin sulfonate, 10-20 parts of chitosan, 10-20 parts of polyvinylpyrrolidone, 10-20 parts of polymeric aluminum sulfate-silicate, 10-20 parts of diacetone acrylamide, 10-20 parts of phosphonate, 10-20 parts of ethylenediamine tetra methylenephosphonic acid and 50-100 parts of deionized water. By controlling and changing the adding sequence of inorganic polymer matter and organic polymer matter with different functional groups and reaction occurrence and nonoccurrence conditions in the recombination process, the purposes of good form distribution and stability of the components before feeding and rapid form conversion and efficient coagulation and flocculability of the components after feeding are achieved.

Description

A kind of sewage disposal solvent

Technical field

The present invention relates to a kind of sewage disposal solvent.

Background technology

Due to population growth and economic development, the excessive exploitation on resource and unreasonable development and the series of problems that affects resource quality that produces, these problems have directly threatened we and descendants's existence.

China is faced with these problems equally, and China is the country of a water resources shortage, how to alleviate the problem such as water resources shortage and pollution and has become an instant problem.

The method of sewage disposal has a lot, but common are Physical and chemical method. Wherein, chemical Treatment sewage be people use maximum. And polyacrylamide the most frequently used water treatment agent in chemical method just. The application of polyacrylamide in water treatment industry mainly comprises aspect three of former water treatment, sewage disposal and Treatment of Industrial Water. In former water treatment, polyacrylamide and active carbon etc. is used in conjunction with, and can be used for cohesion and the clarification of suspended particulate in Living Water; In sewage disposal, polyacrylamide can be used and sludge dewatering; In Treatment of Industrial Water, mainly as prescription medicament. In addition,, in sewage disposal, adopt polyacrylamide can increase the utilization rate of water reuse circulation. Although polyacrylamide is brought into play very heavy effect in water treatment, existing method is all generally to adopt single polyacrylamide, and cost is high, suppresses it and is applied even more extensively.

Secondly, processing water resource pollution problem has physics, chemistry, biology, the several different methods such as comprehensive, but physical method exists treatment effect not good more, handling rate instability problem; Biological method processing cost is too high, is not suitable for promoting the use of; The chemical methodes that adopt are disposed of sewage more, but existing sewage-treating agent, and there is secondary pollution problem in its reagent composition, also can have a certain impact to environment.

Summary of the invention

The object of the invention is to: for the above-mentioned technical problem existing in prior art, provide a kind of low toxicity low evil, high efficiency, low cost, sewage disposal solvent applied widely.

The present invention is achieved by the following technical solutions:

A kind of sewage disposal solvent, is formed and is comprised by following ratio of weight and number configuration: 10～30 parts of diazonium imidazolidinyl ureas, 5～15 parts of methylisothiazolinones, 10～15 parts of medical stone granule :s, 20～30 parts of sodium lignin sulfonates, 10～20 parts of shitosans, 10～20 parts of polyvinylpyrrolidones, 10～20 parts of polymeric aluminum sulfate silicates, 10～20 parts of DAAMs, 10～20 parts of phosphonates, 10～20 parts of ethylene diamine tetra methylene phosphonic acids, 50～100 parts of deionized waters.

Further, also comprise 10～20 parts of beta-mercaptoethanols, 5～15 parts of imvites, 10～20 parts of dimethyl diallyls, 20～40 parts of polymines.

Further, 21 parts of described diazonium imidazolidinyl ureas, 10 parts of methylisothiazolinones, 11 parts of medical stone granule :s, 25 parts of sodium lignin sulfonates, 15 parts of shitosans, 15 parts of polyvinylpyrrolidones, 15 parts of polymeric aluminum sulfate silicates, 15 parts of DAAMs, 15 parts of phosphonates, 15 parts of ethylene diamine tetra methylene phosphonic acids, 60 parts of deionized waters.

Further, 15 parts of described beta-mercaptoethanols, 10 parts of imvites, 15 parts of dimethyl diallyls, 25 parts of polymines.

In sum, owing to having adopted technique scheme, the invention has the beneficial effects as follows: by controlling and changing the order that the inorganic polymer of different functional groups and polymer add, the condition that occurs and do not react in recombination process, reach these components and before adding, keep good form to distribute and stability, after adding, there is very fast Forms Transformation and efficient cohesion flocculability. Can remove pollution and the harmful substances such as the reluctant heavy metal ion of current quo of Conventional Water Treatment Programs, radioactive substance, carcinogen, blue-green algae, SS, COD, BOD, there is the multiple efficacies such as significant decolouring, deodorization, dehydration, de-oiling, degerming. Because sewage treating efficiency is high, function is complete, so process the sewage of same volume, medicament delivery amount only has 1/5 left and right of quo of Conventional Water Treatment Programs, and the operating cost of sewage disposal is low.
