Abstract

The invention discloses a method for treating sewage by using a biological flocculant. The method 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 of chitosan to prepare a component A, and mixing 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 3-5 parts of sodium hexadecyl sulfonate to obtain a component B; B, adding the component A is into sewage to be treated, wherein the adding amount of the component A is 0.1-0.2 kg / ton, conducting standing after sufficient stirring, removing settled matters and then taking a supernatant; and C, adding the component B into the supernatant obtained in the step B, wherein the adding amount of the component B is 0.1-0.4 kg / ton, and after full stirring, filtering a water body by using a filter press to prepare a mud cake. According to the invention, defects in the prior art can be overcome, and the comprehensive flocculation efficiency of the biological flocculant is improved.

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 ...
