Description
Technical field
The present invention relates to a kind of purifying agent for polluted water, especially a kind of high efficiency composition scavenging agent processing town domestic sewage.
Background technology
Along with the mankind increase day by day to the exploitation activity of resource, the development of industrial or agricultural and the growing of population, make to enter in rivers and lakes containing ammonia nitrogen, the sanitary sewage of phosphorus nutrition material, trade effluent, agricultural breeding waste water in a large number, add the load of water nutrition material, its direct result result in body eutrophication.
Lakes and reserviors causes water environment pollution accident to occur repeatedly because of the discharge beyond standards of chemical oxygen demand, ammonia nitrogen, phosphorus, and according to made, what China's Main Lakes was in ammonia nitrogen and phosphorus pollution and caused eutrophication accounts for more than 50% of statistics lake.The eutrophication of water body constitutes harm to people, animal, and serious threat, to the production of the mankind, life and the eubiosis, causes the extensive concern of the people.One of the scarcity and pollution ecological crisis faced having become countries in the world of water resources; only have reduce enter biochemical oxygen demand in water body, ammonia the content of nitrogen and phosphorous is only the effective way solving body eutrophication; and utilize modern science and technology more reasonably to utilize and water conservation, become the only way realizing target of sustainable development.
China is " 12, 13 " period, by carrying out the overall control of chemical oxygen demand (COD) (CODcy), " water prevention and cure of pollution way ten ", become increasingly conspicuous for the water pollutant ammonia nitrogen phosphorus phenomenon that exceeds standard, on March 14th, 2011, the National People's Congress has approved " 12 " planning outline, propose chemical oxygen demand (COD) (CODcy) and reduce 8%, and list ammonia nitrogen (NH4-N) in the binding indicator system first, require minimizing 10%, in pollutant catabolic gene, progressively control to turn to multi-pollution control from Single Pollution thing, ammonia nitrogen phosphorus has become the highest priority that China's water pollutions reduces discharging.
In existing large-scale sewage disposal, biological process and chemical precipitation flocculation treatment method are except NH
4+the most frequently used method of wastewater treatment of-N, P.Although the treatment process of present biology, chemical precipitation process ammonia nitrogen phosphorus waste water has multiple, there is no a kind ofly can to take into account that flow process is simple at present, a method that the everyway such as the convenient and non-secondary pollution of reduced investment, technology maturation, control has advantage.How cost-effective process ammonia nitrogen phosphorus waste water is a difficult problem of pendulum in face of environmentalist, new and effective treatment process and medicament to be put in practical application and to produce good result, to become the emphasis of research application work from now on.
Conventional water purification agent has iron trichloride, ferrous sulfate, Tai-Ace S 150, aluminum chloride, alum, bodied ferric sulfate, poly-ferric chloride, polymerize aluminum chloride etc., these water purification agents respectively have relative merits, but to ammonia nitrogen phosphorus simultaneous removing weak effect, particularly the water purification agent of aluminium salt series is applied in water treatment and can brings a large amount of A1 into
+ 3, can to human brain injury harm, the purifying agent that water treatment field is badly in need of some multifunctional green safety and environmental protections replaces traditional water purification agent product, ensures that people live, water of productive use safety.
Summary of the invention
The object of this invention is to provide a kind of urban wastewater treatment composite purifying agent combined with polymeric silicicacid and Na2Fe04, calcium hydroxide, Magnesium peroxide, synchronously remove ammonia nitrogen phosphorus in waste water, noresidue toxin, non-secondary pollution to realize sewage disposal.
The technical scheme that institute Bian of the present invention gets is:
A kind of town domestic sewage composite purifying agent, is characterized in that: with the part by weight of polymeric aluminium ferrum silicate 20 ~ 70 parts, Na2Fe04 20 ~ 50 parts, 20 ~ 50 parts, calcium hydroxide, Magnesium peroxide 15 ~ 40 parts, make through mixing, ageing, pulverizing, oven dry.
Preferably, with the part by weight of polymeric aluminium ferrum silicate 30 parts, Na2Fe04 25 parts, 25 parts, calcium hydroxide, Magnesium peroxide 20 parts, make through mixing, ageing, pulverizing, oven dry.
Described ageing to refer under normal temperature ageing 24 hours.
The polynary Absorptive complex wave of the present invention's application micella and chemical flocculation precipitation principle, by introducing Mg
2+, Ca
2+ion facilitates Fe
3+hydrolyzate and other positively charged colloid between interaction, the dual compression electrostatic double layer of generation reduces the Mg (OH) that electrolysis generates
2colloid has cellular structure, also has stronger adsorption, and its ambient contamination thing adsorbable, precipitation throw out, make himself weight increase and decline fast, thus colored substance and adsorption of metal ions are got off to be eliminated.When containing Mg in waste water solution
2+, NH
4and PO
3- 4and ionic concn is amassed when being greater than solubility product and can spontaneous production be precipitated, and produces the magnesium ammonium phosphate (MgNH of white
4pO
4).
Reaction formula is as follows:
Mg
2+NH
+ 4+PO
3- 4+6H
2O=MGNH
4PO
4·6H
2O↓
Concrete production process is as follows:
In stainless steel stirring mixer, first put into polymeric aluminium ferrum silicate, then add Na2Fe04; machine and be uniformly mixed 30 minutes, then add calcium hydroxide and Magnesium peroxide, be uniformly mixed 30 minutes; shut down and take out mixture; put into another container ageing 24 hours, do not need heating, be crushed to 150 ~ 200 order numbers; dry; packaging, warehouse-in, obtains product.Can use.
Depending on wastewater and sewage ammonia nitrogen phosphorus content height low degree, every cubic metre of water body uses composite purifying agent 80-150 gram of the present invention.Stir 2 hours, effect is the most obvious.
The appearance of this technology and product, will bring new innovation and significant economic benefit for the urban life waste water of China, trade effluent, agricultural breeding sewage disposal.
The present invention is the NEW TYPE OF COMPOSITE scavenging agent of a kind of siliceous, ferrate flocculent agent and calcic, magnesium ion, which overcome existing inorganic water purification agent, the deficiency that flocculation agent deammoniation nitrogen phosphorus waste water effect is low, utilize silicon, calcium, magnesium, oxonium ion significant synergy complementary action in water purification agent, reach and realize synchronously removing the object of the nuisances such as the ammonia nitrogen phosphorus in waste water, that a kind of performance is more excellent, noresidue toxin; The green phosphor high efficiency composition scavenging agent of non-secondary pollution.Product meets GB4482-2006 water purification agent standard, can be applied to the process of town domestic sewage, agricultural breeding waste water, industrial sewage, reach the primary standard of GB44/26-2001 after making sewage disposal.Be applied to urban wastewater treatment firm, the waste water after process meets " town sewage emission standard GB18918-2002 " one-level sewage drainage standard.And easy to use, cost is low, effective.
