Abstract
A composite water-cleaning agent for treating sewage contains soluble monomer (60-95 wt.%) and insoluble monomer (5-40 wt.%). Its advantages are high efficiency, low cost, and high effect on removing inertial pollutant from sewage.
Description
The present invention relates to a kind of composite water purifying agent of use in waste water treatment
Water is indispensable physical resources in human lives and the activity in production, and recent two decades comes, and along with expanding economy, environmental pollution is more and more obvious.By the pollutant reaction in water purification agent and the water is a kind of effectively and efficiently method that purifies water, one of important channel that the whole world generally purifies water with this method conduct.Japan, America and Europe drop into ample resources in this regard, develop various types of water purification agents.After polymerize aluminum chloride, also developed the polyaluminium salts mixture in recent years.But because on the high side, still difficulty is promoted in China.The water purification agent that mostly is single type of domestic present development and application can only optionally be removed pollutent, and adaptability is narrower.In environmental pollution increasingly serious today, to develop functionally, the water purification agent that efficient is high just seems particularly important.In environmental pollution increasingly serious today, to develop functionally, the water purification agent that efficient is high just seems particularly important.
The purpose of this invention is to provide a kind of efficient, low-cost, can remove the composite water purifying agent of inertia pollutent in the waste water especially.
Technical scheme of the present invention is:
The composite water purifying agent of use in waste water treatment contains soluble and monomeric, accounts for 60～95% and insolubility monomer of gross weight,
Account for 40～5% of gross weight, its efficient oxidation aluminium (Al
2O
3) content necessary 〉=15%.
Soluble and monomeric is selected from one or more in Tai-Ace S 150, aluminum chloride, iron(ic) chloride, aluminium chlorohydroxide, the polymeric aluminum.
The insolubility monomer is chosen one or more in kaolin, wilkinite, diatomite, silica powder, zeolite, alunite.
Soluble monomer preferably earlier is controlled at R≤0.03 millimeter through grinding, particle radius value, and through expanded or acidification.
Various waste water all are to be the dispersion system of dispersion medium with water.Colloidal solid can keep stable two reasons that mainly contain: at first, because similar colloidal particle are electrically identical, the electrostatic repulsion between them stops between particulate closer to each other and aggregate into bigger particle; Secondly, charged micelle and ion can both with water molecules generation hydration on every side, form one deck aquation shell, also hinder the polymerization of each micelle.Micelle is charged many more, and the ε current potential is just big more, and stability is strong more.Water conditioning destroys colloidal stability by adding chemical agent exactly, makes its precipitation, reaches the purpose of purification.By reaction mechanism, can be divided into compression double electric layer, absorption charge neutrality, adsorption bridging, throw out net and catch four kinds.The soluble and monomeric that the present invention selects for use has the chain effect of taking off steady reaction of initiation, control insoluble monomer particle radius and can improve density and the intensity that generates flco, increase insoluble monomeric contact area and can strengthen its adsorption bridging ability, these factors have all improved the efficient that purifies water greatly.
Composite water purifying agent increases its adsorption bridging ability and improves particle diameter, density and the intensity that generates flco when destroying the stability of pollutants in waste water by chemical reaction, has more effect than single type water purification agent.
The present invention compares with single type aluminium salt has following advantage and positively effect: applied range can reach coagulation effect preferably to various wastewater; Form the alum body fast, sedimentation function is good, good decolorizing effect; Suitable pH value and wider range; The unit usage quantity is low than single type.Four aspects play one's part to the full.Thereby has higher purification efficiency.And starting material are easy to get low price.
By the composite water purifying agent that aforesaid method is made, purification of waste water is handled to be applied to stock-farms, food factory, meat processing, sanitary sewage, oil field waste, paper mill, plating, coal washing, print and dye, bleaching and dyeing etc.Its unit usage quantity is lower more than 15% than single type Tai-Ace S 150.And it is particularly remarkable to the inertia pollutant removal.To improving environmental pollution, the protection water resources provides a kind of new method.
To further specify the present invention in following examples, these embodiment only are used to the present invention is described and to the present invention without limits.

Embodiment three:
In the present embodiment composite water purifying agent, polymeric aluminum accounts for 60%, wilkinite, diatomite, silica powder, zeolite respectively account for 10%, wilkinite, zeolite granular radius R are 0.03 millimeter, diatomite, silica powder particle radius R are 0.02 millimeter, and wilkinite, zeolite mix with polymeric aluminum after acidifying through expanded, diatomite, silica powder.Test with sanitary sewage, sanitary sewage CODcr concentration is 181mg/L, add ten thousand respectively/ water purification agent and with the polymeric aluminum of amount, CODcr concentration is respectively 23mg/L and 76mg/L after treatment.The CODcr clearance is respectively 87% and 58%.
