Abstract

The invention discloses a compound uncoupling agent which is used for deweighting treatment of residual sludge in the sewage treatment technology with the activated sludge process. The compound uncoupling agent comprises 3,3,4,5-tetrachlorosalicylamide, refined diatomite and zeolite. When one part by weight of 3,3,4,5-tetrachlorosalicylamide is provided, 0.05-1.0 part by weight of refined diatomite is provided, and 0.05-1.0 part by weight of zeolite is provided. The compound uncoupling agent provided by the invention can obviously lower attenuation on sludge activity while keeping favorable sludge decrement performance and has obvious active effect, which embodies on the aspect that the sludge decrement performance is enhanced, for example, the added TCS can be reduced by 20-60% for reaching the same sludge decrement ratio; after TCS is added in a system, COD strainaway rate is not affected on the whole.

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...
