Abstract

The invention discloses a medicament for sewage purification, which is prepared from the following components in parts by weight: 20 to 30 parts of flocculating agent, 20 to 30 parts of coagulant aid, 15 to 20 parts of defoaming agent, 10 to 20 parts of pH (Potential of Hydrogen) regulator, 20 parts of oxidizing agent, 20 parts of reducing agent, 25 to 35 parts of bentonite and 10 to 15 parts of zeolite powder, specifically, 15 parts of flocculating agent, 25 parts of coagulant aid, 17 parts of defoaming agent, 15 parts of pH regulator, 20 parts of oxidizing agent, 20 parts of reducing agent and 30 parts of bentonite. 13 parts of zeolite powder; according to the medicament for sewage purification and the preparation method, impurities or suspended solids in sewage can be effectively and rapidly precipitated, floccules, impurities and the like can be timely discharged after precipitation, and the medicament has no side effect, does not cause secondary pollution to later sewage and meets the use requirements of sewage purification.

Description

Technical field [0001] The present invention relates to the field of sewage purification technology, in particular to a pharmaceutical agent for sewage purification and preparation method. Background [0002] Sewage usually refers to a certain amount of polluted effluent from life and production. The main sewage is domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogen pollutants, oxygen-depleting pollutants, plant nutrients and toxic pollutants. According to the source of sewage, sewage can be defined as a liquid or water discharged from a residential, institutional, commercial or industrial area mixed with groundwater, surface water, snowstorms, etc. There are many technologies and processes for sewage to be made up of many categories, and there are also many technologies and processes to reduce the impact of sewage on the environment accordingly. According to the source of sewage, sewage can be divided into these four categorie...
