Description
Technical field
The present invention relates to water-treatment technology field, relate in particular to a kind of for drinking water source, sanitary sewage, water treatment flocculant of the high concentrated organic wastewater pre-treatment especially producing for cultivation and chemical industry and preparation method thereof.
Background technology
The coagulating treatment of water is the key link in wastewater treatment, can go turbid scrubbing, reduces the pollution load of sewage subsequent disposal.And flocculation agent is the key factor that determines coagulating treatment effect, the operation conditions of follow-up flow process, final outflow water water quality and cost etc. are had to material impact.
Flocculation agent according to chemical composition can be divided into inorganic flocculating agent and organic floculant two classes, wherein, inorganic flocculating agent can be divided into low molecular flocculant and polymeric flocculant again, low molecular flocculant as the iron such as the aluminium salt systems such as Tai-Ace S 150, aluminum chloride and iron(ic) chloride and ferric sulfate be salt, low molecular flocculant cost is lower, but it has the shortcoming that flocculation sediment speed is slow, amount of consumption of drugs is high.Polymeric flocculant is as aluminum chloride hydrocarbon complex (PAC), polymerize aluminum chloride, bodied ferric sulfate etc., overcome the low shortcoming of processing efficiency that low molecular flocculant exists, but its cost is higher, and when low-temperature and low turbidity poor processing effect.Organic floculant is generally high molecular polymer, as polyacrylamide (PAM), polyamine flocculation agent etc., wherein, polyacrylamide has that consumption is few, primary water mass-energy power is strong, flocculation rate soon, is not subject to the impact of water pH, the advantage such as the sludge quantity of generation is few and obtaining a wide range of applications, but polyacrylamide amount has micro-degradation production when large has certain toxicity, and cost is higher, when weight polyacrylamide is for the treatment of waste water greatly, produce a large amount of polymers residual, destroy water body, and then affect HUMAN HEALTH.Also having a problem is that the organic waste water of existing flocculation agent to high COD, high turbidity, high chroma, does not all have well to flocculate removal effect.In view of this, the technical problem to be solved in the present invention is just to provide a kind of flocculation agent for the treatment of high concentrated organic wastewater.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of flocculation agent for the treatment of high concentrated organic wastewater.
Another technical problem that the present invention will solve is to provide a kind of preparation method of the flocculation agent for the treatment of high concentrated organic wastewater.
Another technical problem that the present invention will solve is to provide a kind of flocculation agent for the treatment of high concentrated organic wastewater for the treatment process of the polluted raw of high chroma, stench.
For the flocculation agent for the treatment of high concentrated organic wastewater, the technical solution used in the present invention is: the component by following parts by weight forms:
PAM5～10, calcium carbonate 20～30, calcium sulfate 20～30, calcium hydroxide 5～15, aluminum contained compound 20～30.
As preferably, aluminum contained compound is Tai-Ace S 150 or polymerize aluminum chloride.
For the preparation method of flocculation agent, the technical solution used in the present invention is: described vitriol, calcium carbonate, Tai-Ace S 150 are dissolved in appropriate water to stirring and evenly mixing;
Reacting by heating 4～5h in the environment of 500 ℃～600 ℃, dries;
Be placed in pulverizer and pulverize 1～3min;
Add described PAM and calcium hydroxide and stir, being placed in shady and cool dry environment and saving backup.
Treatment process for above-mentioned flocculation agent for the polluted raw of high chroma, stench, the technical solution used in the present invention is: in above-mentioned flocculant formula, in 1:1～1:10 ratio, add Powdered Activated Carbon and mix, control dosage is 0.5～1.5g/L.
Compared with prior art, the component that the present invention uses comprises organic floculant and inorganic flocculating agent simultaneously.The present invention can perform to maximum by the advantage of organic floculant and inorganic flocculating agent, has avoided the inferior position of two large components simultaneously.
The calcium sulfate using in flocculation agent provided by the invention, calcium carbonate dissolves hardly, itself plays the effect of the flocculation nucleus of condensation, ionize micro-calcium ion out simultaneously, carbanion, sulfate ion can improve the flocculating effect of flocculation agent greatly, improve and remove COD, ammonia nitrogen, the ability of heavy metal.Again because these components are almost insoluble, so can not introduce new waste.Flocculation agent provided by the invention adopts inorganic flocculating agent Tai-Ace S 150 as main component, is mainly there is no color because Tai-Ace S 150 dissolves, and unlike polymerize aluminum chloride, polyaluminium sulfate is deliquescence so easily; Also unlike bodied ferric sulfate, poly-ferric chloride is deliquescence and the dyeing of also can feeding water so easily, is difficult for preserving.The present invention has added calcium hydroxide in flocculation agent, and the pH of the waste water that can regulate is its meta-alkalescence.Because flocculation component can reach best flocculating effect in alkaline environment, ionization aluminum ion out can be precipitated out simultaneously, the residual quantity of the aluminium in water is dropped to minimum.The present invention also added a small amount of polyacrylamide (PAM), when having improved flocculating effect, reduced residual in water of polyacrylamide, reduced the toxic action to water body biologic chain.The all inorganic componentss of the present invention all easily obtain, and low price, greatly reduce flocculation agent at the cost of actual use procedure.Experiment shows, flocculation agent provided by the invention is during for the treatment of high concentrated organic wastewater, when usage quantity is during at 0.8g/L, processing COD is 8000-10000mg/L, turbidity is 500-1500, plant's waste water of total phosphorus 20mg/L, and COD removes more than 30%, turbidity removal is more than 99%, and total phosphorus is removed more than 90%.Be applied to dyeing waste water, colourity can remove 99.99%.
Processing high concentrated organic wastewater flocculation agent provided by the invention dosage when the wastewater treatment is few, flocculating effect good, residual dose is few, especially for the organic waste water of high COD, high chroma, high turbidity.
