Description
Technical Field
The invention relates to the technical field of wastewater treatment, in particular to an integrated device for treating wastewater in acid pickling and phosphorization production and a treatment process thereof.
Background
The phosphorization treatment is a chemical reprocessing process for the surfaces of metal materials and parts thereof. The surface of metal material and its product after phosphorization treatment forms an immersed phosphate film layer, and said film layer and metal base body have good binding capacity, wear resistance and adhesion capacity to coating material, so that the phosphorization treatment technology can be adopted in the industries of machinery and steel, etc. to make protective layer of mechanical component. The phosphating treatment process generally comprises the steps of alkali washing for removing oil, hot water rinsing, cold water rinsing, acid washing for removing rust, secondary cold water rinsing, phosphating and the like.
The phosphorization production wastewater mainly contains phosphate, nitrate, zinc, iron, nickel and the like, part of wastewater can also contain pollutants such as fluorinion, surfactant and the like according to different production processes, the components are complex, the toxicity is high, the treatment difficulty is high, and the current mainstream process in the phosphorization wastewater engineering practice is as follows: coagulation air flotation, chemical precipitation, sand filtration, activated carbon adsorption, anaerobic and aerobic biochemical treatment and the like.
In contrast, the following patent documents mainly exist at home and abroad: patent publication No.: CN104671493A discloses a neutralization treatment process for acid-washing phosphatization wastewater, which consists of a mixed reaction tank, a sedimentation tank, a mechanical dehydration or sludge drying field and a detection device. The invention has the beneficial effect that the mixed reaction tank mixes the wastewater and the neutralizing agent for full reaction. Insoluble substances after reaction are precipitated in a precipitation tank. The precipitated sludge is subjected to mechanical dehydration or sludge drying. And (4) after the treated water is detected by the detection device to reach the discharge standard, discharging or retreating. However, the treatment method of the patent is too simple, only the neutralization treatment is carried out on the acid pickling phosphorization wastewater through a neutralizing agent, and the treatment effect is not obvious.
Patent publication No.: CN 105174661A discloses an acid pickling phosphating wastewater treatment process, which comprises the following main processes: grid, homogenizing, coagulating, hydrolyzing, anaerobic, aerobic and air floating. The invention has the advantages that the pH value of water can be effectively adjusted, suspended matters and the like in the wastewater can be removed through a coagulation process, and partial phosphates and organic matters in the wastewater can be removed through an anaerobic and aerobic biochemical process. However, the removal capability of the wastewater containing more complex components, such as surfactant and fluoride, higher content of phosphate and nitrate, and metal ions of zinc, iron, nickel and other pollutants is limited, and besides, in practical engineering application, if more process settings are constructed by adopting a civil engineering mode, the cost is higher, and the problems of inconvenient operation and maintenance exist.
At present, an integrated device for treating waste water from acid pickling and phosphorization production and a treatment process thereof with high treatment efficiency are lacked.
