Abstract

The invention belongs to the technical field of environmental protection, and in particular relates to an industrial wastewater purifying agent and a preparation method thereof. The industrial wastewater purifying agent is prepared from the following raw materials in parts by weight: 20-30 parts of modified attapulgite clay, 20-30 parts of polyaluminum chloride, 10-20 parts of chlorine dioxide, 7-12 parts of aluminum iron silicate, 10-20 parts of polyacrylamide, 15-25 parts of alkylphenol polyoxyethylene ether, 5-10 parts of sodium carbonate and 5-15 parts of calcium hydroxide. The industrialwastewater purifying agent has a heavy metal ion removal rate of 97.1% or above, a COD removal rate of 95.6% or above, an oil removal rate of 95.8% or above and a decolorization rate of 97.3% or above, and is good in industrial wastewater purifying effect.

Description

technical field [0001] The invention belongs to the technical field of environmental protection, and in particular relates to an industrial wastewater purifying agent and a preparation method thereof. Background technique [0002] With the increasing development of modern industry, the amount of industrial water and wastewater discharge is increasing, which not only destroys the balance of ecological resources, but also affects people's living environment. At present, the main treatment method of industrial wastewater is the coagulation-flocculation method. Metal salts and organic high molecular polymers act synergistically to destabilize pollutants in wastewater and gather them into separable sediments to purify industrial wastewater. [0003] The publication number is CN107601635A, which discloses a high heavy metal removal rate industrial wastewater purifier and a preparation method thereof. The high heavy metal removal rate industrial wastewater purifier comprises the fo...
