Abstract

The invention relates to a cleaning agent for acidic pollutants in paper-making wastewater. The cleaning agent is prepared from the following raw materials: a Japanese buttercup herb extract, a radixcoptis chinensis extract, a Chinese ephedra herb extract, a shitake mushroom extract, a rhizoma anemarrhenae extract, a fructus forsythiae extract and water.

Description

technical field [0001] The invention relates to the field of water treatment, in particular to an agent for purifying acid pollutants in papermaking wastewater. Background technique [0002] The discharge of waste water in the paper industry is large, and every ton of paper produced will generate 80m 3 Sewage, more than 300 kinds of organic pollutants have been detected in papermaking wastewater, and papermaking wastewater discharge is the sixth largest source of pollution. my country's paper industry wastewater discharge is 3.74 billion tons per year, accounting for 18% of the country's total industrial wastewater discharge, and the chemical oxygen demand (COD) of discharged wastewater is 1.553 million tons, accounting for 33.6% of the country's total industrial COD discharge. The discharge of papermaking wastewater causes the increase of toxic substances in the water body, the death of plankton and fish, and seriously damages the ecological balance. The chemical properti...
