Abstract

The invention discloses a condensing separating disposal of effluent suspension with organics or inorganics, which comprises the following steps: condensing to fix heavy metal; making condensed material not dissolve and leach. The purifying disposing agent consists of front disposal agent and main disposal agent, wherein the front disposal agent is composed of alum and sulphate; the main disposal agent contains 40-60% calcium salt, 30-50% aluminium sulphate, 15-25% alkaline metal carbonate and 1-5% organic agglomerant.

Description

Organic sewage purifying agent

Technical field:

The present invention is under state of nature, can not dissolve, the more dirty purification of waste water treatment agent of stripping again.The present invention is mainly used in the SS that comprises in the dirty draining, reach the dispersion that is contained in the dirty draining, the numerous organic substance in outstanding turbid, the partly soluble dirty draining, by simple treatment unit, chemical transformation takes place, can make the agent of mineral compound agglutinative coagulation sedimentation.

Background technology:

In recent years, the dirty problem of water quality becomes very great society problem., the solution that can not find, the enterprise and the producer that seek countermeasure are not within minority.The draining benchmark is strict all the more now, and everybody is very worried.

Summary of the invention:

The present invention is exactly at the problems referred to above, provide a kind of and can carry out effective aggegation separating treatment at the sewage of the outstanding absurd creature that contains organism or inorganics, and, also can handle the aggegation of heavy metal and fix, aggegation fixed thing can not dissolve again, stripping.

The present invention adopts following technical scheme: purifying agent of the present invention, constituted by purifying pretreating reagent and purifying main treating agent, purifying pretreating reagent is made up of alum class and Sulfates, purifying main treating agent is by calcareous salt 40-60 weight %, Tai-Ace S 150 30 weight-50 weight %, alkali is given birth to metal carbonate 15-25 weight %, organic system agglutinant 1-5 weight %, and cooperation forms.Use this agent that the SS in the dirty draining is separated simultaneously with the dirty material of organic property, make it to remove, isolating mud can reclaim after the use of this agent, simultaneously owing to there is not the chemistry burden of intensity, so under state of nature, can not decompose again, make it keep shakedown.

Beneficial effect of the present invention:

1, main application of the present invention: the draining of general manufacturing (chemistry, electrical equipment, automobile, mining industry, food, metal processing etc.) is handled.The mixing draining of organism and inorganics contains the draining of heavy metal, the draining of high BOD and COD, the aggegation of dirty material that contains the draining etc. of phosphorus and Chisso collects fixedly separated and handles water purification (according to circumstances recycling) and the processing of mud takes place, following drainage facility, the wastewater treatment of dung urine refining plant and the processing of generation mud, pre-treatment (the phosphorus of various dirty water, the chamber element, BOD and COD, the minimizing of SS etc., foul smell reduces, the colourity transparence), the lifting promotion of mud and the raising of dehydration property take place, the purification and the mud stabilization of the special draining of building relation, lakes and marhshes, the rivers and creeks, the separation of the mud that takes place during the purification in bay etc., the processing of the car washer draining of service station etc.

Embodiment:

1, be powder, sewage to be processed does not need to adjust PH before the processing when the scope of PH5-9.The PH of the treating water after aggegation separates almost is a neutral.

2,, the eutrophication of water quality is prevented that countermeasure from also producing effect because the low effect height that subtracts of BOD and COD.Sorption is heavy metal (chromium, lead, copper, cadmium, mercury) or other metals (manganese, cobalt, molybdenum, inferior lead, iron etc.) fixedly, no longer stripping.Handle the also no longer stripping of waste sludge that the back produces, these characteristics also are the important point concerning people's healthy protect.

3, the processing of food processing wastewater or kitchen waste water can improve the corrupt smelly of water significantly.When but containing material (F, B, N etc.), aggegation is preferably handled preceding adjustment before separating.

4, the separated sludge that obtains after handling is become granularly by hydrophobization, become mud part of extremely utilizing dehydration, from separated sludge than being easier to carry out drawing of moisture.Therefore, helpful to the harden minimizing of (industrial waste that the terminal stage of processing obtains) of dehydration.

Using method: addition is decided according to dirty material or dirty concentration.For treating water, the scope of 50-300ppm (mg/l) (SS concentration ratio 0.5-1.0) is an amount of.

After medicament adds, Qiang Li stirring a little, conditions permit, aggegation in 1-3 minute separation is over, and it is better also to continue mixing effect.After the aggegation separation was over, stopping to stir aggegation mud several minutes will precipitate.

Precipitin reaction takes place, and the transparent treated water layer can appear in top, handles fully, and the boundary line for the treatment of water and precipitating sludge can be distincter.

But, the processing aggegation that contains heavy metal water separates a little times of how many needs.The precipitation of aggegation mud began the back about 30 minutes, and medicament just can capture in dissolved heavy metal part, need leave standstill a moment again.Stability by the isolating aggegation mud of aggegation is very high, and external force such as restir add that the heavy metal part that captures can not dissolved again.

Aggegation separates the mud that obtains, and because of hydrophobicity becomes granule, shows to be suitable for dehydration property and good machine adaptability.Obtain the good dehydration of low the hardening property of water ratio.

Embodiment 2:

The alum class of above-mentioned purification pretreating reagent is the plural salt that vitriol cooperated by Tai-Ace S 150, basic metal carbonate, thallium, ammonium ion, forms the purification pretreating reagent of the dirty draining of organic system among the application.

Embodiment 3:
