preparation example Construction

[0020] The preparation method of the uncoupling agent of the present invention is relatively simple, and only needs to simply mix the various components. Moreover, in the actual application process, each component can also be added to the sewage treatment system separately.

[0021] The present invention also provides the application of the above-mentioned uncoupling agent in the process of treating sewage by activated sludge method.

[0022] In a specific application process, it is only necessary to add the decoupling agent into the reaction system for treating sewage by activated sludge method. The amount of the uncoupling agent may be 0.1-10 mg, preferably 1-3.5 mg, per liter of sewage to be treated. Since the decoupling agent of the present invention can show strong sludge reduction performance in the process of treating sewage by activated sludge method, in order to obtain the same sludge reduction rate as the existing decoupling agent The uncoupling agent of the presen...

Abstract

The invention relates to an uncoupling agent containing 2,4,5-trichlorophenol, a soluble metal salt and an adsorbent, wherein the soluble metal salt is soluble ferric salt and / or soluble aluminum salt. The invention also relates to the application of the uncoupling agent to an activated sludge method for the treatment of wastewater. In the process of the activated sludge method for the treatment of wastewater, the uncoupling agent provided by the invention can realize high COD removal rate and sludge reduction rate, and the water outlet has small TP concentration.

Description

technical field [0001] The invention relates to an uncoupling agent and the application of the uncoupling agent in the process of treating sewage by activated sludge method. Background technique [0002] Activated sludge method is one of the widely used urban sewage treatment methods at present. Compared with other treatment methods, its biggest advantage is that it can save treatment costs, and its disadvantage is that a large amount of surplus activated sludge is produced in the actual operation process. The treatment cost of excess activated sludge is quite high, generally accounting for 25% to 65% of the total operating cost of the sewage plant. Therefore, the treatment and disposal of excess activated sludge has become one of the main problems that plague sewage treatment plants. At present, the sludge reduction process is an important means of residual activated sludge disposal. Commonly used sludge reduction processes mainly include delayed aeration, aerobic or anaer...
