Abstract

The invention provides a compounded decoupling agent, which is used for performing reduction treatment on excess sludge in an aerobic sewage treatment process through an activated sludge method. The compounded decoupling agent comprises the components of 3,3,4,5-tetrachlorosalicylamide and zeolite powder in a weight ratio of the 3,3,4,5-tetrachlorosalicylamide to the zeolite powder of 1:(0.1-1.5). The compounded decoupling agent provided by the invention can obviously reduce the attenuation on the activity of sludge while keeping good sludge reduction performance, and has a very obvious positive effect and stronger performance embodied in the sludge reduction; by adopting the compounded decoupling agent, the added TCS can be reduced by 20 to 60 percent to achieve the same sludge reduction rate; and when the TCS is added into a system, the COD removal rate is basically not affected.

Description

technical field [0001] The invention relates to a decoupling agent, in particular to the decoupling of residual sludge used in the activated sludge aerobic treatment process for sewage treatment, and the main component is 3,3,4,5-tetrachlorosalicylamide joint agent. Background technique [0002] Activated sludge method is currently the most widely used sewage (including urban sewage or industrial sewage) biological treatment technology, although this process technology has many advantages, such as less investment in infrastructure, good treatment effect, stable operation, etc., but it also has a The obvious disadvantage is that a large amount of residual sludge will be generated during operation. The cost of excess sludge treatment is quite high, generally accounting for 25% to 65% of the total operating cost of the sewage plant. Therefore, reducing or reducing the generation rate of excess sludge in the activated sludge sewage treatment process has always been a subject of...
