Abstract

The invention relates to a preparing method for a sewage treating solvent. The sewage treating solvent is prepared from, by weight, 10-30 parts of diazolidinyl 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 poly-silicon aluminum sulfate, 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. According to the method, the adding sequence of inorganic polymer matter and organic polymer matter which have different functional groups and conditions for reacting and non-reacting in the compounding process are controlled and changed, so that it is achieved that components are maintained in good form distribution and stability before being added, and achieve quick form transformation and efficient condensation and flocculability after being added.

Description

A kind of preparation method of sewage disposal solvent

Technical field

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

Background technology

Due to population growth and Economic development, the series of problems affecting resource quality produced the excessive exploitation of resource and unreasonable development, these problems have directly threatened the existence of we and descendants.

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 is the maximum of people.And the water treatment agent that polyacrylamide is the most frequently used in chemical method just.The application of polyacrylamide in water treatment industry mainly comprises in original sub-block, sewage disposal and Treatment of Industrial Water three.In original sub-block, polyacrylamide and gac etc. with the use of, can be used for cohesion and the clarification of suspended particle in Living Water; In sewage disposal, polyacrylamide can be used and sludge dewatering; In Treatment of Industrial Water, be mainly used as prescription medicament.In addition, in sewage disposal, polyacrylamide is adopted can to increase the rate of utilization of Water circulation circulation.Although polyacrylamide plays very heavy effect in water treatment, existing method is all generally adopt single polyacrylamide, and cost is high, suppresses it to be applied even more extensively.

Secondly, process water resource pollution problem has physics, chemistry, biology, the multiple method such as comprehensive, but to there is treatment effect not good more for physical method, processing rate instability problem; Biological method processing cost is too high, is not suitable for promoting the use of; Many employings chemical process is disposed of sewage, but existing sewage-treating agent, and there is secondary pollution problem in its agent formulations, 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 existed in prior art, provide a kind of low toxicity low evil, high efficiency, low cost, sewage disposal solvent applied widely and preparation method thereof.

The present invention is achieved by the following technical solutions:

A preparation method for sewage disposal solvent, its concrete steps are as follows:

(1) measure starting material according to above-mentioned mass fraction, clean mixing of materials prepares stirrer, adds secondary deionized water 50 ~ 100 parts;

(2) nitrogen Imidurea 10 ~ 30 parts, methylisothiazolinone 5 ~ 15 parts, medical stone granule: 10 ~ 15 parts are slowly added material and be mixed with in stirrer, record churning time, preparing stirrer to the end required time that feeds intake from unlatching mixing of materials is 10 minutes;

(3) by sodium lignosulfonate 20 ~ 30 parts, chitosan 10 ~ 20 parts, polyvinylpyrrolidone 10 ~ 20 parts, polymeric aluminum sulfate silicate 10 ~ 20 parts, slowly add material and be mixed with in stirrer and stir;

(4) slowly drop into phosphonate 10 ~ 20 parts, ethylene diamine tetra methylene phosphonic acid 10 ~ 20 parts under normal pressure, temperature is less than 50 DEG C, and terminate until reinforced, whole process completed in 30 minutes;

(5) slowly diacetone-acryloamide(DAA) 10 ~ 20 parts, beta-mercaptoethanol 10 ~ 20 parts, polynite 5 ~ 15 parts, dimethyl diallyl 10 ~ 20 parts, polymine 20 ~ 40 parts is dropped under normal pressure, temperature is less than 50 DEG C, terminate until reinforced, whole process completed in 30 minutes, pH controls between 8 ~ 10, stop mixing of materials preparing stirrer, the examination and test of products is packed.

In sum, owing to have employed technique scheme, the invention has the beneficial effects as follows: by controlling and changing the inorganic polymer of different functional groups and the order of polymer interpolation, the condition occurring in recombination process and do not react, reach these components before adding, keep good fractions distribution and stability thereof, there is after adding very fast form transformation and efficiently condense flocculence.Pollution and the objectionable impurities such as current quo of Conventional Water Treatment Programs reluctant heavy metal ion, radioactive substance, carcinogenic substance, blue-green algae, SS, COD, BOD can be removed, there is significant decolouring, deodorization, dehydration, de-oiling, the multiple efficacies such as degerming.Due to dirt

Water treatment efficiency is high, function is complete, so the sewage of process same volume, medicament delivery amount only has about 1/5 of quo of Conventional Water Treatment Programs, and the running cost of sewage disposal is low.
