Abstract
The invention discloses a method for retreating wastewater reclaimed water containing phosphorus and fluorine, in particular multilevel treatment of wastewater. The method comprises the following steps of: adding common ions I (Ca(OH)2 solution) and flocculating agent poly aluminum chloride (PAC) into reclaimed water, reacting for 10 minutes, adding hydrolyzed polyacryamide (HPAM), and precipitating for 5 minutes; taking supernatant liquor, reversely adjusting pH value to be 2 to 3 by using H2SO4; and adding common ions II (CaCO3 solution) and and the flocculating agent PAC and reacting for 10 minutes, and precipitating for 5 minutes to ensure that the wastewater meets the standard of surface water III grade water. By using the method, the treated wastewater can meet the surface water III grade water, lays firm foundation for zero emission and resource utilization maximization, and saves a large amount of water resources; and the method is easy to operate, and is high in stability, and low in removal cost.
Description
Technical field
The present invention relates to that the phosphate fertilizer industry is phosphorous, water is handled again in the fluoric acid wastewater, relates in particular to the multiple-stage treatment of waste water.
Background technology
In the treating processes of phosphorous at present, fluoric acid wastewater, adopt secondary lime acid-base neutralisation method more.Adopt this method, waste water on average can reach " GB15580-95 phosphate fertilizer industrial water pollution thing emission standard " large-scale two period of one-level emission standard after treatment, for bigger contribution has been made in environment protection.
But along with the raising of China to environmental protection requirement; in the prior art as 200810208139.X " middle water recovering process "; " 91100227.8 fluorinated water treatment process "; " 01138004.7 treating method for high fluorice acid waste water "; " 200410089993.0 the method that a kind of fluoride waste is handled "; " 200510072860.7 fluorine-containing wastewater treatment method and treatment agent thereof "; though these technical schemes have all proposed about the effective ways of wastewater treatment, and be unrealized to the recycling of after treatment water (water in the abbreviation).The principle that the present invention recycles in line with resource as far as possible, centering water is further handled, and saves great amount of water resources.
Summary of the invention
The purpose of this invention is to provide a kind of middle water treatment process that is fit to phosphorous and fluorine, and water outlet P≤0.2mg/L, F
-≤ 1mg/L reaches surface water III class water quality standard, the more extensive reuse of water in the realization.
Realize technical scheme of the present invention take in the water-quality guideline of water water sample see the following form:
Realize that technical scheme of the present invention comprises the second-stage treatment mode:
First order reaction is to add homo-ion I (Ca (OH) in middle water
2Solution) and flocculation agent PAC, allow its reaction 10min, add HPAM again, precipitation 5min;
Second order reaction is to add homo-ion II (CaCO in the process middle water of above-mentioned processing
3Solution) and flocculation agent PAC reaction 10min, make its precipitation 5min again, can reach surface water III class water quality standard and carry out reuse.
The middle water of described second order reaction is through H
2SO
4The anti-pH that transfers is the supernatant liquid of 2～3 first order reaction.
Described homo-ion I (Ca (OH)
2Solution) concentration is 5%～10%, homo-ion II (CaCO
3Solution) concentration is 3%～5%.
Advantage of the present invention: flow process and simple to operate only needs second-stage treatment (secondary reaction, secondary sedimentation); It is few to add medicament kind; Treatment effect is good, good stability, and cost is low.
