Industrial wastewater treatment agent based on multi-effect phosphorus removal

Abstract

A kind of industrial wastewater treatment agent based on multi-effect dephosphorization disclosed by the present invention, in the reactor with reflux condensing device, add 240kg of dimethyl diallyl ammonium chloride cationic monomer, diallylamine 10 kg, 8 kg of glacial acetic acid, heat up to 82°C, add 0.2kg of compound initiator, control the reaction temperature not to exceed 100°C, add 0.2kg of compound initiator after natural cooling to 82°C, and then add 0.3kg composite initiator, after heating up, heated to 95°C for 2 hours to prepare cationic polymer for later use. In another reactor, add 60 parts of water, 100 parts of industrial hydrochloric acid, 10 parts of ferric chloride, 60 parts of calcium aluminate, and stir the reaction. When the temperature rises to 80°C, add 10 parts of the cationic poly Raise the temperature to 90~95°C, react for 4 hours, discharge and mature for 24 hours to get the product. The product prepared by the invention has excellent phosphorus removal effect, and simultaneously has functions such as flocculation, decolorization, deodorization, and COD removal.

Description

technical field [0001] This patent relates to the preparation technology of a multi-effect phosphorus removal agent, an industrial wastewater treatment agent with excellent phosphorus removal effect and functions of flocculation, decolorization, and COD removal, which belongs to the field of environmental protection water treatment agents. Background technique [0002] Traditional phosphorus removal methods in the sewage treatment industry mainly include chemical precipitation and microbial methods. The basic principle of chemical precipitation is to add one or several metal ions that can form precipitation with phosphate, and remove phosphate from water by generating insoluble phosphate. Precipitants commonly used in traditional phosphorus removal methods include aluminum, iron, and calcium salts such as calcium chloride, polyaluminum chloride, polyferric sulfate, aluminum sulfate, aluminum trichloride, ferric chloride, and ferrous chloride. Since the phosphorus removal ...
