The present invention relates to a kind of vibro-grinding Waste Water Treatment and processing method.The vibro-grinding Waste Water Treatment includes wastewater collection pond, electric flocculation device, the first pH regulating reservoirs, the first sedimentation basin, dosing pond, ultraviolet irradiation device, the 2nd pH regulating reservoirs and the second sedimentation basin being sequentially communicated.The vibro-grinding method of wastewater treatment comprises the following steps：Collect vibro-grinding waste water, electric flocculation processing, the pH value of waste liquid after regulation electric flocculation processing simultaneously carries out one-level precipitation, the first supernatant that one-level is precipitated is transferred in dosing pond, ferrous sulfate and hydrogen peroxide are added successively, it is circulated between dosing pond and ultraviolet irradiation device and carry out Primary UV irradiation, then adjust pH value and carry out two-stage precipitation, reclaim the second supernatant.Using the processing method of the vibro-grinding waste water of the vibro-grinding Waste Water Treatment, the COD value and total nitrogen content of vibro-grinding waste water, high treating effect can be significantly reduced.
Description
Technical field
The present invention relates to field of waste water treatment, more particularly to a kind of vibro-grinding Waste Water Treatment and processing method.
Background technology
Generally, vibro-grinding is referred in oscillating mill by according to a certain percentage mixing abrasive material with pending product
It is combined the process for being rotated, vibrating and being ground towards processed products.The materials such as ceramics, porcelain, jade, synthetic resin
The metal material of material and the PROCESS FOR TREATMENT such as stamped, casting, forging, die casting, its surface needing to polish, polish, gloss is beaten
The process treatment process such as light, chamfering, burr removing, often have and use vibro-grinding technique.
The pretreatments such as treating material needs to be cleaned before grinding into oscillating mill, de-oiling degreasing, shake
Also need to add abrasive solution in dynamic process of lapping.Material after vibro-grinding is handled, it is necessary to re-start cleaning again.
In above procedure, substantial amounts of emulsifying liquid waste water, abrasive waste water and cleaning waste water can be produced.Wherein, organic dirt in emulsifying liquid waste water
Contaminate thing content very high, COD (Chemical Oxygen Demand：COD) value is from up to ten thousand milligrams per liter to more than 100,000
Milligrams per liter, but also the materials such as substantial amounts of oily substance and solid suspension can be contained.Vibro-grinding waste water and cleaning are useless
The COD value of water generally also can be very high, and according to different production processes, its COD value is generally in more than 5000mg/L.Three of the above is given up
Water, can also exist because manufacturing technique requirent can be added containing nitrogen compound, thus in final waste water a certain amount of nitrate nitrogen or
Person's ammoniacal nitrogen.Do not have the introducing of heavy metal ion during vibro-grinding, so being typically free of heavy metal in abrasive waste water
Ion.But generally had in vibro-grinding waste water and cleaning waste water and the metal fragment come, resin, ceramic chip and mill is ground
Material debris.Above-mentioned waste water, is translucent or opaque turbid solution under normal circumstances.
At present, the processing of the waste water produced during vibro-grinding belongs to industrial problem.Lead to especially in above-mentioned waste water
Such as stearic acid material often contained, belongs to high-leveled and difficult chemical degradation and high-leveled and difficult biodegradable pollutant.
The content of the invention
Based on this, it is necessary to provide a kind of vibro-grinding Waste Water Treatment to vibro-grinding good waste water treatment effect and
