Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a composite multi-effect sewage treatment flocculant and a preparation method thereof. Background technique [0002] Industrial wastewater often contains copper, nickel, lead and other heavy metal ions or their complex ions. Such heavy metal ions or their complex ions are stable in the natural environment, can accumulate in organisms, and have chronic toxicity. If they cannot be properly handled, they will have a serious impact on agriculture and fisheries, and endanger human health. It is one of the serious problems facing the environment, and there is a large amount of organic waste in industrial wastewater. At present, the flocculants used in sewage treatment plants to treat industrial wastewater take a long time to flocculate and settle, and the production process is complicated, the cost of the product is high, and the removal effect on biological inhibitors, organ...
