Description
Technical field
The present invention relates to wastewater from mechanical industry processing technology field, specifically disclose at a kind of Treatment of Metal Surface waste water
Reason method.
Background technology
There are coolant, organic cleaning fluid, painting wastewater, Treatment of Metal Surface waste water, electric spark work in mechanical processing process
Make the discharge of wastewater such as liquid.Although these wastewater flow rates are seldom but organic concentration is very high, wherein coolant CODCr is up to 50000
~300000mg/L, if without processing directly discharge serious pollution can be caused to environment.It is domestic that high concentration mechanical is processed
There is bottleneck in the processing of waste water, its CODCr successfully can be down to thousands of mg/L by many combined treatment process, but is intended into one
It is but very difficult that step improves treatment effeciency.China to discharged in machining high concentration, emulsification serious oily waste water yet
To fine processing
During Treatment of Metal Surface, acid washing phosphorization technique is relatively conventional, and it is as a kind of metal coating technique, with certain anti-
The effectiveness of burn into resistance to oxidation, and be also the procedure on coated metal, it has more important value function.But
Through metal after acid washing phosphorization technique is carried out, corresponding waste water will necessarily be produced, wherein substantial amounts of harmful ion is included, and
Acid-base value is relatively low, and certain harm is easily produced to environment.
The content of the invention
The purpose of the present invention is to overcome the deficiencies in the prior art there is provided a kind of Treatment of Metal Surface method of wastewater treatment, is adopted
Waste water is handled with lime, the acidity of waste water can not only be reduced, while can also make calcium phosphate precipitation, promotes phosphonium ion
Concentration obtain certain control, moreover, using lime treatment technique, can also reduce the concentration of other heavy metal ion, and
The handling process has certain economy, for highly basic handling process, and lime treatment technique more possesses environmentally friendly spy
Property, the friendly for environment has also obtained certain lifting.
The present invention is adopted the following technical scheme that to achieve these goals：
A kind of Treatment of Metal Surface method of wastewater treatment, described Treatment of Metal Surface method of wastewater treatment comprises the following steps：
（1）, waste water separation
Suspension, metallic foreign body, oil slick will be separated into waste water using separator and waste water is just handled；
（2）, suspension processing
Above-mentioned gained suspension is poured into mummifying pool, low temperature desiccation；
（3）, metallic foreign body processing
Above-mentioned gained metallic foreign body is poured into high-temperature smelting pot and is heated to 500~600 DEG C, 5 minutes are incubated, natural cooling；
（4）, oil slick processing
Above-mentioned gained oil slick is added in stirring-type reactive tank, mixes, treats while adding a certain amount of milk of lime and being stirred with it
It stops stirring after fully reacting, and stands 8~10 hours, extracts supernatant out using water pump and is poured into just processing waste water, profit
Bottom turbid solution is transported to desiccation in mummifying pool with dredge pump；
（5）, just handle wastewater treatment
First processing waste water is added in stirring pool, mixed while adding a certain amount of milk of lime and being stirred with it, treats that it is fully anti-
Should after stop stirring, stand 1~2 hour, stirring pool bottom turbid solution be transported to desiccation in mummifying pool using dredge pump, then to stirring
Mix and a certain amount of dilute sulfuric acid regulation pH value added in pond, finally the water conservancy in stirring pool is evacuated in sand filter with water pump, filtered,
Clear water after filtering is transported to biological treatment tank purification.
Further, described step（5）Middle low temperature desiccation temperature is 50~70 DEG C.
Further, described step（5）Middle pH value control 6.5~7.5.
Further, described biological treatment tank includes pond body, the pasture and water and nitrobacteria being planted in pond body.
Compared with prior art, implementation result of the invention is as follows by the present invention：
A kind of Treatment of Metal Surface method of wastewater treatment of the present invention, is handled waste water using lime, can not only dropped
The acidity of low waste water, while can also make calcium phosphate precipitation, promotes the concentration of phosphonium ion to obtain certain control, moreover, using
Lime treatment technique, can also reduce the concentration of other heavy metal ion, and the handling process has certain economy, relatively
For highly basic handling process, lime treatment technique more possesses environmental protection characteristic, and the friendly for environment has also been obtained necessarily
Lifting.
