Abstract

The invention discloses an agricultural sewage treatment agent and a preparation method thereof. The sewage treatment agent comprises the following raw materials in parts by weight: 30-40 parts of anadsorbent, 15-20 parts of chitosan, 10-20 parts of sodium alginate, 10-20 parts of carbon nanotubes, 10-15 parts of modified beta-cyclodextrin, 10 -15 parts of starch, 10-15 parts of sepiolite, 5-10 parts of cellulose, 5-8 parts of chlorophyll and 3-5 parts of a bactericide. The agricultural sewage treatment agent provided by the invention can effectively remove pesticide residues from sewage, reduces the eutrophication degree of the water quality, and effectively recycles heavy metal pollutants contained in water so as to ensure that after treatment, the water quality meets standards of farmland irrigation and industrial water.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an agricultural sewage treatment agent and a preparation method thereof. Background technique [0002] Agricultural sewage refers to the sewage or liquid substances discharged during the process of crop cultivation, livestock raising, and agricultural product processing, which affect human health and environmental quality. Its sources mainly include farmland runoff, feedlot sewage, and agricultural product processing sewage. Sewage contains various pathogens, suspended solids, fertilizers, pesticides, insoluble solids and salt, etc. The amount of agricultural sewage is large and the impact is wide. Nutrients such as nitrogen and phosphorus in sewage enter rivers, lakes, inland seas and other waters, which can cause eutrophication; pesticides, pathogens and other toxic substances can pollute drinking water sources and endanger human health; Extensive soil pollution disrupts the b...
