Composite inorganic high-molecular waste water treatment flocculant

Abstract

The invention discloses a composite inorganic high-molecular waste water treatment flocculant which is composed of following raw materials, by mass: 40-70% of polyaluminium ferric sulfate, 2-10% of magnesium sulfate, 5-10% of cationic starch, 4-15% of calcium hydroxide, 0.5-3% of activated charcoal, 2-10% of sodium carbonate and 5-15% of polyacrylamide. The flocculant is broad in spectrum, is low-toxic, is low-cost in the raw materials, is good in treatment effects, is simple in operation, is wide in available range, and can form the floc being good in filterability. The flocculant can effectively treats oil-containing waste water, coking wastewater and such industrial waste water, can protect ecologic environment, is less in use amount, can form large alumen ustum, is high in sedimentation speed, is high in removal rate of COD, is less in sludge, is strong in adsorbability on pollutants and is strong in neutralization capacity on micro-acidic waste water.

Description

technical field [0001] The invention relates to the field of sewage treatment materials, in particular to a composite inorganic polymer sewage treatment flocculant for sewage treatment. Background technique [0002] The methods used in industrial sewage treatment include physical, chemical, physicochemical and biochemical methods. Most water treatments require an upfront chemical treatment process. Chemical methods can be divided into neutralization method, flocculation method, redox method, ion exchange method and so on. The coagulation and flocculation method in the chemical treatment method is the most widely used, the most economical and the most important treatment method, which can remove small particles of colloidal substances in the water body. The flocculant is the key factor for the success of the flocculation method. However, when the wastewater to be treated is a stable and complex dispersed system, such as in recent years, oily wastewater, coking wastewater, ...

AI Technical Summary

Problems solved by technology

However, when the wastewater to be treated is a stable and complex dispersed system, such as in recent years, oily wastewater, coking wastewater, and other industrial wastewater, traditional flocculants and inorganic polymer flocculants cannot meet the treatment requirements, causing pollution to the ecological environment More seriously, how to effectively flocculate these stable and complex dispersed sewage is a problem that needs to be solved
