Abstract
The invention discloses a preparation method of a sewage treatment agent. Residual activated sludge in sewage treatment is processed and then mixed with other assistants, so as to prepare the sewage treatment agent. The preparation method is simple in operation, and the prepared sewage treatment agent is low in cost, good in effect and applicable to large-scale production. By adopting the sewage treatment agent prepared by the method disclosed by the invention, the removal rate of effluent suspended solids after treatment can be up to 99.8%, the biochemical oxygen demand (BOD) removal rate is 98%, the chemical oxygen demand (COD) removal rate is 98.5%, and the chromaticity is 5.
Description
Technical field
The present invention relates to technical field of sewage, particularly relate to a kind of preparation method of sewage-treating agent.
Background technology
The main process of to take activated sludge process as the biologic treating technique of representative be current sanitary sewage and most of trade effluent, after the processing power decline of active sludge, the utility value of residual active sludge just reduces, and residual active sludge is generally used as farmland fertilizer etc.The sewage-treating agent etc. of main organism containing microorganism, Institute of Micro-biology's absorption and microbiota metabolic activity product in excess sludge, sludge condensation and conditioning, and some sandy soil and salt inorganics etc.The a large amount of microorganism wherein contained and polysaccharide, protein, cellulosic material, still can be used as biological sewage treatment agent in sewage disposal, play a role in sewage disposal, its cost is lower, but the residual active sludge after wastewater treatment directly uses, weak effect, therefore, how residual active sludge being recovered as efficient sewage-treating agent, is the problem needing now to solve.
Summary of the invention
Object of the present invention is exactly defect for above-mentioned existence and provides a kind of preparation method of sewage-treating agent.By the standby one-tenth of residual actived sludge in sewage disposal sewage-treating agent, effective, cost is low, is applicable to scale operation.
Preparation method's technical scheme of a kind of sewage-treating agent of the present invention is that step is as follows:
(1) sewage treatment plant residual mud is mixed with water, filter;
(2) filtrate in step (1) is added concentration be 10% hydrochloric acid condition pH be 2-4, add hydrogen peroxide simultaneously, after stirring, centrifugation;
(3) granulator granulation is entered after being mixed with silicon-dioxide, sodium-acetate, polyacrylamide, EDTA, wilkinite, ferrous sulfate by the solid matter that centrifugation in step (2) obtains.
In step (1), the filter screen filtered is 80-200 order.
The mass percent adding hydrogen peroxide in step (2) is 0.1%.
In step (2), stirring velocity is 200-500r/min, and churning time is 15-30 minute.
In step (3), solid matter and silicon-dioxide, sodium-acetate, polyacrylamide, EDTA, wilkinite, ferrous sulfate are by weight:
Beneficial effect of the present invention is: the present invention mixes with other auxiliary agents after being processed by residual active sludge in sewage disposal again, prepare sewage-treating agent, simple to operate, the sewage-treating agent cost prepared is low, to the Be very effective that the impurity in waste water flocculates, and take full advantage of residual active sludge, solve the recycling problem of residual active sludge.Sewage-treating agent prepared by the inventive method, after process, to reach 99.8%, BOD clearance be 98%, COD clearance to wastewater suspended substance clearance is 98.5%, and colourity is 5.
