Abstract

The invention discloses a composite water treatment agent for heavy metal wastewater treatment. The composite water treatment agent for the heavy metal wastewater treatment is prepared from the components of polyglutamic acid, starch, FeCl3.6H2O, FeSO4.7H2O, sodium silicate, humic acid, diatomite magnesium stearate, sugarcane waste residues, polyethylene glycol and tributyl phosphate. The preparation method includes the steps that (1), modified Fe3O4 particles are prepared, specifically, the polyethylene glycol and the FeCl3.6H2O and FeSO4.7H2O react to prepare the modified Fe3O4 particles; (2), magnetic composite microspheres are prepared, specifically, the polyglutamic acid, the starch and the sodium silicate are placed in a reactor, and compounded with the modified Fe3O4 particles underthe action of sodium hydroxide, an initiator and a cross-linking agent to prepare the magnetic composite microspheres; and (3), the diatomite and the sugarcane waste residues are activated at high temperature, then mixed with the magnetic composite microspheres, activated mixtures and the humic acid to obtain the composite water treatment agent under the action of magnesium stearate, the tributylphosphate, a coupling agent and a dispersant.

Description

technical field [0001] The invention belongs to the technical field of heavy metal wastewater treatment, and in particular relates to a composite water treatment agent for heavy metal wastewater treatment and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of economy and the rapid improvement of industry, society has made great progress, but at the same time, human beings are also facing more and more serious environmental problems. The main environmental problem at present is the pollution of heavy metals. Heavy metals cannot be biodegraded. On the contrary, they will be enriched by hundreds of thousands in the biological food chain, and finally enter the human body. They will interact strongly with proteins and enzymes in the human body, causing them to slowly inactivate. It is enriched in certain organs in the human body, causing chronic poisoning and seriously endangering human health. The sources and quantities of...
