Abstract

The invention relates to a sewage treatment composite gel material for microbe embedding, and a preparation method thereof. The sewage treatment composite gel material for microbe embedding comprises, by weight, 60-80 parts of carrageenan, 5-15 parts of polyacrylamide, 5-8 parts of porous starch, 4-8 parts of microbes, 0.1-0.3 parts of a growth factor, 1-4 parts of inorganic powder, 1-3 parts of a cross-linking agent and 0.5-0.8 parts of a potassium salt. The composite gel material is prepared by adopting carrageenan and the polyacrylamide composite gel as an embedding agent, the porous starch as an adsorbent and a carrier and the inorganic powder as an additive, is used for embedding microbes, is applied to sewage treatment, can effectively adsorb and remove heavy metal ions and degrade organic matters, and has the advantages of simple preparation process, low cost and market application prospect.

Description

technical field [0001] The invention belongs to the field of sewage treatment, and in particular relates to a sewage treatment composite gel material embedding microorganisms and a preparation method thereof. Background technique [0002] Water accounts for 70% of the earth's area, of which seawater accounts for 97.3%, and available fresh water accounts for only 2.7%. 77.2% of fresh water exists in snow-capped mountains and glaciers, 22.4% exists in soil and groundwater (precipitation and surface water infiltration), only 0.4% Surface water is rivers, lakes, glaciers and other water bodies. Overview of my country's water resources: The total length of rivers and rivers in my country is 420,000 kilometers, and the lakes are 75,600 square kilometers, accounting for 0.8% of the total land area. The total water resources are 2.8 trillion m 3 , 2,300 cubic meters per capita, accounting for only 1 / 4 of the world's per capita possession, ranking 121, and one of the 13 water-poor c...
