The invention has the advantages that: by combining the electrolytic deposition technology with the membrane separation technology, the device has the advantages of less investment, high handle capacity, low energy consumption, high benefit, easy industrialization and easy implementation of the comprehensive utilization of resources; the effluent discharge after reaching standards and the recycling are realized, the heavy metal resources in the wastewater are effectively recycled; and automation degree is high and manual operation is simple and convenient, the complete recovery and zero discharge of heavy metals can be basically realized and water resources are completely recycled and the wastewater is deeply purified.
Description
Technical field
The present invention relates to wastewater treatment equipment, specifically relate to the galvanic deposit-membrane separation combined treatment device of electrolytic zinc poaching wastewater.
Background technology
Heavy metal wastewater thereby is to environment and the great pollutent of human health risk, along with the appearance of a series of enviromental protection laws and standard, to the requirement of heavy metal containing wastewater treatment also increasingly stringent.Heavy metal wastewater thereby results from numerous industries and industrial sectors such as metallurgy, plating, chemical industry, electronics, machinofacture and processing.Efficiently when removing heavy metal ions in wastewater, realize that it is the developing direction of heavy metal containing wastewater treatment from now on that waste water recycling and heavy metal reclaim.When the chemical wastewater treatment unit is handled heavy metal-containing waste water, owing to contain a large amount of organic complexs in many heavy metal wastewater therebies, limited the chemical settling process, the waste water heavy metal content after causing handling exceeds standard.Though it is low that tradition biological wastewater treatment device has a cost, handles advantage easily, owing to be subjected to the influence of wastewater toxicity, be difficult to extensive the realization, and the efficient of handling is low, effect is relatively poor.The Applied Electrochemistry wastewater treatment equipment when heavy metal concentration in the waste water reduces, existed energy consumption big, the problem that treatment effect is relatively poor in the past.
Along with the increasingly stringent of environmental requirement, independent a kind of technology often can not well reach this purpose.
Summary of the invention
The objective of the invention is to overcome weak point of the prior art, a kind of galvanic deposit-membrane separation combined treatment device of electrolytic zinc poaching wastewater is provided.
The objective of the invention is to be achieved through the following technical solutions: the galvanic deposit-membrane separation combined treatment device of electrolytic zinc poaching wastewater, comprise liquid-inlet pipe, equalizing tank, electric deposition device, the three-dimensional fixation bed apparatus, security personnel's strainer, three recycle pumps, membrane module, clear water output and concentrated solution return port, wherein: equalizing tank is between liquid-inlet pipe and recycle pump, the left end of recycle pump links to each other with equalizing tank, the right-hand member of recycle pump links to each other with the electric deposition device entrance end, the exit end of electric deposition device links to each other with the three-dimensional fixation bed apparatus, the left end of recycle pump links to each other with the three-dimensional fixation bed apparatus, the right-hand member of recycle pump links to each other with security personnel's filter inlet end, security personnel's filter outlet end links to each other with membrane module, recycle pump liquid material is squeezed into membrane module again through security personnel's strainer, the left end of recycle pump links to each other with the concentrated solution return port, the right-hand member of recycle pump links to each other with the left end of membrane module, the right-hand member of membrane module links to each other with clear water output, clear liquid can directly be discharged reuse from clear water output, concentrated solution is got back to electric deposition device by the concentrated solution return port, and system finishes one batch cycle operation.
Described membrane module is multistage low pressure reverse osmosis film, and working pressure is 0.6～1.6 MPa, and service temperature is 5～60 ℃.
Waste water at first is collected in the reuse tank after pre-treatment, and reuse waste water carries out preliminary filtration treatment with disc filter to former water, to remove the fouling precipitation that some macrobead suspended substances and inorganic salts are separated out.In this project according to the concentration situation of waste water heavy metal ion, take multistage electroreduction device, be plate electrode electrolysis electric deposition device and fixed bed three-dimensional electrolysis device, binding film components apart device, utilize the huge sum of money water waste water after reverse-osmosis membrane element concentrates to return, carry out electroreduction once more and reclaim heavy metal components, clear water is back to use in the production process.
The present invention compared with prior art has following advantage:
1, combined electrical deposition and membrane separation technique have less investment, treatment capacity is big, energy consumption is low, high efficiency, easily industrialization, easily realize comprehensive utilization of resources.
2, realize water outlet qualified discharge and when recycling, heavy metal resources in the efficient recovery waste water.
3, the concentration of metal ions in the membrane concentration liquid obtains, improve a lot than the concentration of metal ions in the raw wastewater, combine, be highly suitable for the electrolytic recovery heavy metal with electro-deposition techniques, both solve the situation that concentrated solution is difficult to handle, be easy to realize circulating Reuse of Waste Water again.
4, galvanic deposit and membrane separation process level of automation height, manual operation is easy, is can realize substantially reclaiming fully and zero release to the heavy metal contaminants of industrial poaching wastewater water resources complete-reclaiming, the associated plant of realization waste water advanced purifying.
