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 biologic treating technique that the activated sludge process of take is representative is the main treatment process of current sanitary sewage and most of trade effluent, after the processing power of active sludge declines, the utility value of residual active sludge just reduces, and residual active sludge is generally used as farmland fertilizer etc.In excess sludge, mainly contain the absorption of microorganism, Institute of Micro-biology organism and microbial metabolism activity product, mud is concentrated and the sewage-treating agent of conditioning use etc., and some sandy soil and salt inorganics etc.The a large amount of microorganisms that wherein contain and polysaccharide, protein, cellulosic material, still can in sewage disposal, be used as biological sewage treatment agent, in sewage disposal, play a role, its cost is lower, but the residual active sludge after wastewater treatment is directly used, weak effect, therefore, how residual active sludge being recovered as to efficient sewage-treating agent, is to need now the problem of solution.
Summary of the invention
Object of the present invention is exactly that a kind of preparation method of sewage-treating agent is provided for the defect of above-mentioned existence.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) being added to concentration is that 10% hydrochloric acid condition pH is 2-4, adds hydrogen peroxide simultaneously, after stirring, and centrifugation;
(3) after mixing with silicon-dioxide, sodium-acetate, polyacrylamide, EDTA, wilkinite, ferrous sulfate, solid matter centrifugation in step (2) being obtained enters granulator granulation.
In step (1), the filter screen that filters use is 80-200 order.
The mass percent that adds 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 by after residual active sludge in sewage disposal is processed again, prepare sewage-treating agent, simple to operate, the sewage-treating agent cost of preparing is low, the effect that impurity in waste water is flocculated is remarkable, and take full advantage of residual active sludge, solved the recycling problem of residual active sludge.Sewage-treating agent prepared by the inventive method, it is that 98%, COD clearance is 98.5% that the rear wastewater suspended substance clearance of processing reaches 99.8%, BOD clearance, colourity is 5.
