Abstract

The invention discloses a method for treating sewage by using a biological flocculant, which comprises the following steps: A. preparing the biological flocculant; mixing 25-35 parts of polyferric sulfate, 3-5 parts of sodium silicate and 10-15 parts Chitosan is mixed to prepare component A; 40-50 parts of corncob powder, 10-15 parts of activated carbon particles, 20-30 parts of walnut shell powder, 5-10 parts of potato starch and 3- Mix 5 parts of sodium cetyl sulfonate to prepare component B; B, put component A into the sewage to be treated, the input amount of component A is 0.1-0.2kg / ton, fully stir and let it stand , take the supernatant after removing the sediment; C, put component B into the supernatant obtained in step B, the input amount of component B is 0.1~0.4kg / ton, use a filter press to filter the water body after fully stirring Filter and make a mud cake. The invention can improve the deficiencies of the prior art and improve the comprehensive flocculation efficiency of the biological flocculant.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment method using a biological flocculant. Background technique [0002] As my country's environmental protection continues to increase, how to quickly and efficiently treat sewage has become one of the research hotspots in this field. In the process of sewage treatment, flocculants are commonly used to coagulate and adsorb pollutants in sewage. Bioflocculant is a kind of flocculant prepared by using biological materials. It has been widely used in recent years due to its low cost, non-toxicity, and no secondary pollution. However, due to the low comprehensive flocculation efficiency of bioflocculants, the amount of use is relatively large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a sewage treatment method using a biological flocculant, which can solve the deficiencies of the prior art ...
