Abstract

The invention discloses a river channel sewage treating agent and a preparation method thereof; the river channel sewage treating agent comprises chitosan, polyacrylamide, a microbial agent, modified attapulgite clay, activated carbon, diatomite, sodium chloride, zeolite, polyaluminum chloride, limestone, and saw dust. The preparation method comprises: adding the chitosan, modified attapulgite clay, activated carbon, sodium chloride and polyaluminum chloride into a reaction container, adding water, mixing, and ultrasonically treating for 20-30 min; adding the microbial agent and polyacrylamide, mixing, soaking for 20-40 min, drying the mixture, and crushing; mixing well saw dust, diatomite, zeolite and limestone with the crushed mixture. The treating agent of the invention is applicable to river channel sewage treatment, and can adsorb and settle contaminants in a river channel and degrade the contaminants to clear the river channel sewage thoroughly.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a river sewage treatment agent and a preparation method. Background technique [0002] my country is a country with a shortage of water resources. The per capita water resources are only 1 / 4 of the world's, and the distribution of water resources is seriously uneven. How to alleviate the shortage of water resources and pollution has become an urgent problem. In order to solve the problem of water shortage, in addition to increasing sources of income, reducing expenditure, and comprehensive utilization, pollution control has gradually become one of the basic principles that our country must adhere to for a long time. At present, there are many methods to deal with the pollution of water resources, such as physics, chemistry, biology and synthesis. The physical method is to recover the insoluble suspended pollutants in the sewage through physical separation. This method c...
