Abstract
A sewage treating agent with high speed and effect is prepared from attapulgite clay through acidifying, baking, adding alum and modified starch, and grinding. The generated mud is a good organic fertilizer.
Description
Technical field
The present invention relates to the environmental protection field, be specifically related to a kind of Attapulgite sewage-treating agent and production method.
Background technology
Along with development of industry and agriculture, strengthen scientific and technological development to efforts at environmental protection, become the important topic of relevant scientific research department, the various product innovations that are used for environmental protection constantly put into production, have obtained achievement preferably.Be used for chemical industry at present, brewage, the description of materials of industry sewage disposal such as medicine, papermaking is a lot, mainly contain: activated carbon, diatomite, zeolite, wilkinite and attapulgite clay, and other chemicals etc.
China Patent No. 99118670, February 19 2003 Granted publication day, denomination of invention: " a kind of preparation method of industrial sewage treating agent ", a kind of preparation method of industrial sewage treating agent is disclosed, this method is bentonite, iron powder, aluminium lime-ash, kaolin, carnallitite to be mixed to stir earlier, adds hydrochloric acid reaction chemical combination again and forms.Less investment of the present invention, cost are low, simple.
Foregoing invention less investment, low, the simple advantage of cost arranged really, still, " bentonite, iron powder, aluminium lime-ash, kaolin, carnallitite are mixed stir earlier, add hydrochloric acid reaction chemical combination again and form." working method, state not in detail, for example, wilkinite, kaolin, carnallitite are to use raw ore, still with the finished product after the processing; 20～26% concentrated hydrochloric acid (actual concentrations of concentrated hydrochloric acid is unclear) by weight percentage, after dilution, directly add in the mixture of bentonite, iron powder, aluminium lime-ash, kaolin, carnallitite, be difficult to stir, because the water-intake rate extra-heavy of bentonite, iron powder, aluminium lime-ash, kaolin, carnallitite; The finished product of foregoing invention is a particulate state, or powdery is not illustrated yet; Sewage disposal is a various lots of job, need to use a large amount of sewage-treating agents, and some raw material in the buying foregoing invention has certain degree of difficulty.
Summary of the invention
The objective of the invention is to overcome weak point in the prior art, a kind of Attapulgite sewage-treating agent and production method are provided.
Production method of the present invention is to use attapulgite clay as raw material, dries after acidification, adds alum and the common abrasive dust of treated starch, and finished product is the Attapulgite sewage-treating agent.
Attapulgite clay is a kind of moisture magnesium alumino metasilicate salt mine, and it has performances such as good adsorption, decolouring, because the inner porous of attapulgite clay road, specific surface area is big, can reach 500m
3More than/the g, most positively charged ion, water molecules and a certain size organic molecule all can directly be adsorbed in the duct, are difficult for being flocculated by ionogen, have good stability in high temperature and salt solution; Alum is the more stable coagulating agent of a kind of performance, and treated starch is the natural polymer sorbent material, because starch has flocculation and biochemistry helps the effect of coagulating, can improve sewage and remove ability, reusable after the sorbent material desorb, and some precious metal ion, also recyclable, increase economic efficiency.The above-mentioned raw material that is used for the production waste treatment agent, supply channel is extensive, low price.
The present invention is achieved by following technical proposals:
1, select materials: attapulgite clay dries after 20～60 days through natural weathering, and moisture answers≤13%, and alum should be selected quality crystal alum preferably for use, and general starch can not be used, and must be treated starch.
2, batching (1) (weight percent): attapulgite clay 48～65%, water 33～50%, sulfuric acid (concentration is 98%) 0.5～5%, each component summation=100% (weight).
3, acidifying: be sprayed at behind the Dilution of sulphuric acid on the attapulgite clay, stir, piled up 24～48 hours with stirrer.
4, oven dry: be transported in the dryer and dry, bake out temperature is controlled at 120～160 ℃, and the attapulgite clay moisture after the oven dry answers≤5%.
5, batching (2) (weight percent): Concavo-convex excellent stone clay after the acidify 50～90%, alum 3～30%, treated starch 2～25%, each component summation=100% (weight).
6, abrasive dust: the common abrasive dust of Concavo-convex excellent stone clay after the acidify, alum and treated starch, fineness≤0.074mm is packaged as finished product.
Using method: after sewage enters settling tank, at first remove various floating matters, according to the particular case of sewage, the Attapulgite sewage-treating agent of adding 0.1～2.0%, towards turning over for several times, quicken the effect of Attapulgite sewage-treating agent and sewage, at short notice with high-pressure pump, sewage will produce the flocculence suspended substance, and rapidly natural sedimentation, reaching the purpose of decolorizing purification sewage, the water after the clarification can reach emission standard, or put into another pond, circulation utilizes once more.Throw out in Attapulgite sewage-treating agent and the sewage can be stayed in the settling tank, adds part Attapulgite sewage-treating agent slightly, both can enter the processing of next round sewage.Mud in settling tank can change mud in the sludge sump over to and deals with in addition more for a long time.
Characteristics of the present invention are:
1, flocculation reaction speed is fast, the clearance height, and the water quality after handling is limpid, and the waste residue water ratio is low, and sludge volume is little, and dewatering is good.
2, stable performance, the temperature of use and pH value wide ranges are not subjected to the restriction in season, zone in the use, and are convenient to store and transportation.
When 3, adopting Attapulgite sewage-treating agent of the present invention, adding and flotation or sedimentation facility of medicament can utilize existing treatment facility, need not to increase and build, and running cost is low, and the scope of application is wide, and is simple to operate, easy to use.
4, water purification after the processing and mud can utilize or discharge once more through after the suitable processing, and mud is a kind of good organic fertilizer.
The Attapulgite sewage-treating agent is mainly used in town sewage and handles, and also is applicable to chemical industry, brewages, the sewage disposal of industries such as medicine, papermaking.
Embodiment:
The invention will be further described below in conjunction with embodiment.
1, select materials: the kind of attapulgite clay is a lot, should choose the reasonable attapulgite clay of absorption property, pick up and remove the assorted stone of visible and other foreign matter, allow its natural weathering 45 days, constantly disintegration is less irregular block thing, and is dried, moisture answers≤13%, alum should be selected quality crystal alum preferably for use, and general starch can not be used, and must be treated starch.
2, batching (1) (weight percent): attapulgite clay 60%, water 37% and sulfuric acid (concentration is 98%) 3%.
3, acidifying: after sulfuric acid slowly added entry, be sprayed on the attapulgite clay, be deposited in together the various material react withs in sulfuric acid and the attapulgite clay after stirring in the input stirrer, to reach the activatory purpose, normal temperature activation 36 hours.
4, oven dry: be transported in the dryer and dry, in oven dry, further strengthen the activatory effect, bake out temperature is controlled at 120～160 ℃, and the attapulgite clay moisture after the oven dry answers≤5%.
