Description
Technical field
The present invention relates to a kind of composite type water treating agent that utilizes mineralized waste for the major ingredient preparation, this water conditioner can be used for the pretreatment technology of high concentrated organic wastewater, indegradable industrial effluent, can tentatively remove the pollution substances such as suspended matter, larger molecular organics matter and heavy metal in the waste water, provide high-activity microorganism for follow-up bioprocess technology simultaneously.
Background technology
Existing water conditioner can be divided into inorganic and polymer two big classes, as polyaluminium salts, molysite and polyacrylamide etc.These water conditioners are mainly removed suspended substance and larger molecular organics matter in the waste water in the mode of chemical flocculation precipitation, use comparatively extensive in water technology.But these water conditioners can't self be realized the regeneration of processing power, so these water conditioners only can once use, and can't repeat or use for a long time, have brought the problem of water treatment sludge subsequent disposal.
Summary of the invention
The purpose of this invention is to provide the composite type water treating agent of a kind of preparation based on mineralized waste, this water conditioner has that multiple processing mechanism acts synergistically, can use for a long time, the characteristics of economical and efficient.
For achieving the above object, the present invention is a major ingredient with mineralized waste fines in the household refuse landfill sites, adds auxiliary materials such as cement clinker and limestone activity material simultaneously.In water treatment, can realize physical adsorption, ion-exchange, hydration reaction, chemical precipitation and bio-transformation mechanism synergy like this, thereby reach suspended substance, larger molecular organics matter and heavy metal in the preliminary removal waste water, under biotransformation, realize the self-regeneration of water conditioner processing power simultaneously.
Composite type water treating agent based on mineralized waste provided by the invention, its component and content (weight percentage) are:
Mineralized waste 80～100%
Cement clinker 0～20%
Wingdale 0～20%
Wherein the weight ratio of cement clinker is a cement: gypsum=80～100: 0～20%
Each component sum of water conditioner must equal 100%
The optimum ratio of water conditioner of the present invention (weight percentage) scope is:
Mineralized waste 85～95%
Cement clinker 4～10%
Limestone powder 1～5%
Water conditioner provided by the invention prepares by the following method:
The first step: the preparation of major ingredient: the landfill mineralized waste of age in the period of 4-15 in the excavation household refuse landfill sites, cross aperture 20-100mm scalping, sieve component is down done the natural air drying processing, controls this mineralized waste water ratio 15～50%.Mineralized waste after the air-dry processing is crossed 2～5mm dusting cover, and component is as the major ingredient of water conditioner under the sieve.
Second step: the preparation of auxiliary material: under normal temperature condition, cement and gypsum are mixed according to aforementioned proportion, make cement clinker, then cement clinker and Wingdale are ground to 60～200 orders respectively, standby as the water conditioner auxiliary material.
The 3rd step: choose mineralized waste fines, cement clinker powder and limestone powder according to the above ratio, under normal temperature condition, it is mixed, can make composite water disposal agent of the present invention through grinding.
Compare with existing water conditioner, the present invention has the following advantages:
1. the major ingredient mineralized waste of forming this water conditioner has bigger specific surface area, higher cation exchange capacity, can remove organism and nitrogen phosphorus eutrophication pollution thing in the waste water by physical adsorption, ion-exchange, chemical precipitation and biotransformation, so treatment effect is comprehensive.
2. be enriched with a large amount of superior microorganism populations in the mineralized waste fines, these microorganisms have very that Johnson ﹠ Johnson deposits and degradation capability, can realize the regeneration of water conditioner processing power, are artifact treatment process acclimation and screening superior microorganism population simultaneously.
3. hydration reaction can take place in tricalcium aluminate in cement clinker and the limestone powder and tetracalcium aluminoferrite isoreactivity material in water surrounding, generates gel and alkaline matter.These hydrated products can adsorb and fixedly larger molecular organics and heavy metal ion in the waste water.Therefore this water conditioner treatment effect is good.
4. because the resource of mineralized waste is very sufficient, can think to get without cease use not to the utmost, the preparation technology of water conditioner and use technology simple.So economic benefit of the present invention and environmental benefit are fairly obvious.
5. the processing of Fa Ming water conditioner load is big, and cost of water treatment is low, can be used for the pretreatment technology of various high concentrated organic wastewaters and indegradable industrial effluent.
