The present invention relates to sewage treating material technical field, be specifically related to the high efficiency composition flocculant that a kind of sewage disposal feature of environmental protection is excellent.
Background technology
Although the earth has the area of 70.8% to be covered by water, but freshwater resources are extremely limited, and really being able to by our utilization is the part in rivers and lakes and subsoil water, and these only take up an area the 0.26% of ball total Water, and skewness.After the fifties in last century, population in the world sharp increase, industrial boom, incident is that the rapid of global water resources situation deteriorates, and " water crisis " is on the rise.On the one hand it is that the demand of water resource is increased by the mankind with surprising rapidity；On the other hand, the water being on the rise pollutes nibbles the water resource being available for consumption in a large number.
Water pollution condition is constantly aggravated, cause people more and more to pay close attention to, especially in economically underdeveloped area, wantonly discharge without the sewage administered and cause local natural environment severe exacerbation, and cause the pollution of subsoil water to a certain extent, and effect a radical cure these contaminated need for environments and expend the time of several generations.The reason wantonly discharged of sewage without administering is caused to have a lot, the reason such as the highest including discharger's environmental consciousness, government regulation is the tightest, and most important reason is the relatively costly of current waste water control, water treatment efficiency is undesirable.The processing method of existing sewage mainly includes bioanalysis, chemical method and Physical, wherein chemical method exists that processing cost is higher and secondary pollution problems, the cost of Biochemical method sewage is relatively low, but the domestication of microbial strains and purification limit the further development of Biochemical method technology always；Physical is mainly flocculation adsorption and processes, but the flocculating effect that existing flocculation adsorption processes material is unsatisfactory, and the follow-up improvement of difficult degradation flocculation material for large usage quantity is much to seek suitable solution.
Summary of the invention
Not enough for prior art, the invention provides the high efficiency composition flocculant that the feature of environmental protection of a kind of sewage disposal is excellent.
The present invention solves the technical scheme of above-mentioned technical problem employing: a kind of feature of environmental protection high efficiency composition flocculant, including following raw material: FeOCl, PAMC, activated carbon fiber, activated alumina, modified Punica granatum L. stone sand, PPFS, porous type hydroxylapatite powder, polyamino many ethers methylenephosphonic acid (PAPEMP), dimethyl diallyl ammonium chloride-acrylamide copolymer, meerschaum, slaked lime powder and bagasse magnesium lignosulfonate；The mass fraction of described raw material is: FeOCl 10 ~ 20 parts, PAMC 20 ~ 35 parts, activated carbon fiber 2 ~ 10 parts, activated alumina 4 ~ 8 parts, modified Punica granatum L. stone sand 5 ~ 15 parts, PPFS 3 ~ 6 parts, porous type hydroxylapatite powder 1 ~ 5 part, polyamino many ethers methylenephosphonic acid (PAPEMP) 10 ~ 15 parts, dimethyl diallyl ammonium chloride-acrylamide copolymer 5 ~ 10 parts, meerschaum 3 ~ 8 parts, slaked lime powder 1 ~ 2 part and bagasse magnesium lignosulfonate 3 ~ 6 parts.
Further, described a kind of feature of environmental protection high efficiency composition flocculant, including the raw material of following mass fraction: FeOCl 15 parts, PAMC 25 parts, activated carbon fiber 6 parts, activated alumina 6 parts, modified Punica granatum L. stone sand 10 parts, PPFS 5 parts, porous type hydroxylapatite powder 3 parts, polyamino many ethers methylenephosphonic acid (PAPEMP) 12 parts, dimethyl diallyl ammonium chloride-acrylamide copolymer 8 parts, meerschaum 5 parts, slaked lime powder 1 part and bagasse magnesium lignosulfonate 5 parts.
Further, described modified Punica granatum L. stone sand is hydrochloric Acid Modification Punica granatum L. stone sand, uses the Punica granatum L. stone sand granule of 30 ~ 80 mesh to soak 1 ~ 2h under room temperature through the hydrochloric acid of concentration 10%, the Punica granatum L. stone sand after rinsing, drying.
Compared with prior art, the advantage that the present invention possesses is: the composite flocculation agent of the sewage disposal that the present invention provides uses environmental protection flocculation material or to have the natural material of excellent flocculating property be raw material, there is the good feature of environmental protection, secondary pollution will not be produced after sewage flocculation is administered；By rational raw material choice, gained composite flocculation agent can realize excellent flocculability, and to BOD clearance in sewage up to more than 80%, SS clearance is up to more than 90%, and also has preferable removal effect for sewage heavy metal and other pollutants；The composite flocculation agent using method of the present invention is easy, only need the 0.1%-0.3% being incorporated as sewage quantity at normal temperatures can obtain good soil release performance, and it is low to use the composite flocculation agent of the present invention that sewage carries out administer energy consumption, treatment cost is low, high treating effect, especially for the sewage after simple coagulation, use the composite flocculation agent of the present invention to can reach discharge standard after processing, contribute to improving domestic waste water control present situation.
