Description
Technical field
The present invention relates to a kind of treatment process of heavy metal-containing waste water, relate in particular to a kind of in addition electric field-enhanced micro electrolysis tech and handle the method that heavy metal-containing waste water reclaims heavy metal resources in the waste water, belong to technical field of waste water processing.
Background technology
Be accompanied by the fast development of industries such as China mine, smelting, plating, metal processing, chemical industry, pigment, the throughput of enterprise improves constantly, and produces a large amount of heavy metal-containing waste waters in the production process; And the waste water water yield is increasing, if these heavy metal-containing waste waters directly are thrown into environment, not only can cause serious pollution to water body or other environmental factorss; And can produce huge potential threat to human body, the destruction because the heavy metal in the environment can not be decomposed, and the transformation of physics, chemical form can only take place; Biological magnification heavy metal through food chain obtains enrichment in vivo; The final human body that gets into produces heavy metal poisoning, jeopardizes HUMAN HEALTH and even life security, simultaneously; The direct discharging of heavy metal-containing waste water also can cause the significant wastage of resource, brings the internal diseconomy property of enterprise.For this reason, must be before the heavy metal-containing waste water discharging through treatment and purification reaching the emission standard requirement, and metals resources in the maximum dynamics recovery waste water, turn waste into wealth.
At present, the treatment technology to heavy metal-containing waste water can reduce chemical method, physico-chemical processes, biological process three major types substantially.Electrochemical process is owing to advantages such as it has clearance height, recoverable metal resource, environment compatibility is good, secondary pollution is little more and more receive efforts at environmental protection person's favor in numerous treatment processs.
And the micro-electrolysis method in the electrochemical process is the processing of heavy metal-containing waste water a kind of new approach is provided; This method is to utilize iron filings, gac etc. to make micro-electrolysis stuffing; With waste water is electrolyte solution; Through heavy metal in the reaction of the galvanic cell between the little electrolysis particle galvanic deposit waste water, reach the purpose that purifying waste water processing reclaims metals resources.This method is compared the traditional chemical method can turn waste into wealth, and handles waste water through the means of the treatment of wastes with processes of wastes against one another, and this method also has advantages such as energy consumption is low, processing cost is low, easy and simple to handle simultaneously, in heavy metal-containing wastewater treatment, has a extensive future.Develop some through efforts at environmental protection person's unremitting effort and be directed to little electrolysis treatment technology of heavy metal-containing waste water; As: patent 200910218380.5 discloses a kind of " micro-electrolysis treatment method of lead-zinc smelting wastewater "; Patent 201010293120.7 discloses a kind of " method of a kind of iron-carbon micro-electrolysis treatment of high concentration cupric antibiotic waste water and recovery copper "; Patent 201010503732.4 discloses a kind of " interior electrolysis-electrolytic process is handled heavy metal-containing waste water " or the like, the application of constantly having expanded micro electrolysis tech.
But; Because micro-electrolysis method only utilizes the galvanic cell effect of himself; Can only form faint electric current and voltage at little electrolysis particle surface, and the catalyzed reaction of this current/voltage is limited in one's ability, this must bring long, problem such as processing efficiency is on the low side of wastewater treatment time; And then cause that water treating equipment are excessive, compliance rate is on the low side, limited micro electrolysis tech applying in heavy metal-containing wastewater treatment.
The problem that exists during to the little electrolysis treatment of heavy metal-containing waste water; How through improve, improvement should technology or exploitation United Technologies; Under the prerequisite that keeps traditional micro electrolysis tech advantage, effectively solve above-mentioned drawback problem, become an important techniques problem thereby handle heavy metal-containing waste water efficiently, economically.
Summary of the invention
The present invention has overcome the deficiency and the shortcoming of traditional micro electrolysis tech, provides a kind of in addition electric field-enhanced micro electrolysis tech to handle the method for heavy metal-containing waste water, and this is the method that efficient treatment and purification of a kind of heavy metal-containing waste water and metals resources reclaim.
For realizing the object of the invention; The present invention strengthens traditional little electrolysis galvanic cell reaction through the introducing of external electric field; Produce bigger galvanic current and voltage; Improve the catalyzed reaction ability,, handle back water and can directly discharge or be back to production process in the shortest reaction times, to reach the highest heavy metal place to go rate.
The inventive method intensifying technology process object is various types of heavy metal-containing waste waters or contains heavy metal organic waste water, like smelting wastewater, mine wastewater, beneficiation wastewater, electroplating wastewater, pharmacy waste water etc.; Also can be various types of organic waste waters, like dyeing waste water, food processing wastewater etc.
