Description
Technical field
The utility model relates to technology for treating industrial waste water, especially a kind of low concentration heavy metal water film electrolytic processing apparatus.
Background technology
Heavy metal wastewater thereby is environmental pollution and the mankind is endangered to one of maximum trade effluent, in environment, be difficult for by metabolism, and repair difficulty, physical environment and daily life are caused to very serious harm, for example, Poland causes approximately 50% surface water not reach water quality grade III Standard by digging up mine and smelting refuse; " bone aching " that cause because of cadmium in " minamata disease " that Japan's Minamata bay is caused by mercury poisoning and basin, magic river, the copper staining that " the blood lead event " that the ground Lead contaminations such as Fengxiang, China Shaanxi cause, Fujian Zijin Mining seepage accident cause etc. are all that heavy metal contamination brings the typical case of infringement true to HUMAN HEALTH and environment.
Along with the development of China's economy, society, shortage of water resources, water pollution problems are on the rise.Relevant statistics shows, China's heavy metal wastewater thereby accounts for 10% of wastewater emission amount, mainly from industry such as plating, wiring board, mining, metallurgy, chemical industry, have the heavy metals such as potential hazardness, particularly mercury, cadmium, lead, chromium and have significant bio-toxicity, micro-concentrations can produce toxicity, under microbial process, can be converted into the organometallic compound that toxicity is stronger (as methyl mercury), or be bioaccumulation, by food chain, enter human body, cause chronic poisoning.
At present, process for treating heavy-metal waste water has flotation process, ion exchange method, electrolytic process, biochemical process, microorganism and algae processing, phytoremediation etc., by heavy metal wastewater thereby, administer, take by poisonous turn to nontoxic, will be harmful to be converted into harmless, and reclaim noble metal wherein, the measures such as waste water circulation use by after purifying, reach the object of eliminating and reducing the quantity discharged of heavy metal.But, when the heavy metal content in water is very low, in aforesaid method, deionization exchange process is all inapplicable outward, ion exchange treatment method is to utilize the method for objectionable impurities in the separated waste water of ion-exchanger, the ion-exchanger of application has ion exchange resin, zeolite etc., and ion exchange resin has gel-type and macroporous type.The former has selectivity, and the latter manufactures complexity, disposablely has high input, floor space is large, regenerative elution liquid easily causes secondary pollution, resin vulnerable to pollution, thereby is very limited in application.
Film electrolysis tech is called again ion-exchange membrane electrolysis, it is the new technology growing up on the basis of ion exchange resin, utilize cationic exchange membrane that unit electrolytic bath is divided into anolyte compartment and cathode compartment, utilize ion-exchange membrane to there is to yin, yang ion the characteristic that selection sees through, the ion of a kind of electric charge of allowed band passes through by limiting the ion of opposite charges, to reach the object such as concentrated, separated.Film electrolysis tech is able to widespread use (as ion-exchange membrane electrolysis alkaline) in commercial run in recent years, but, the electrolyzer of applying in current industrial and diaphragm sell, be mainly for the high density heavy metal industrial effluent Treatment Design producing in the Industrial processes such as metallurgical and caustic soda, and be not suitable for the Industrial Wastewater Treatment that heavy metal ion content is lower.
Summary of the invention
The deficiency existing in order to overcome prior art, the utility model provides a kind of low concentration heavy metal water film electrical treating device, this low concentration heavy metal water film electrical treating device, be applicable to process the heavy metal wastewater thereby under low consistency conditions, adopt ion-exchange membrane, under the effect of DC electric field, the heavy metal ion in heavy metal wastewater thereby is carried out to separation, not only make waste water be purified, and reached the object that the heavy metal ion in waste water is reclaimed.
The technical scheme of the invention for solving the technical problem, comprise cell body, water inlet pipe, battery lead plate support, positive plate, negative plate, bellows, perforated pipe, blast main, rising pipe and shore pipe, wherein, described cell body is closed rectangular structure, cell body is provided with water inlet pipe and rising pipe on longitudinal two side, on water inlet pipe one side channel body wall, there is unthreaded hole, described blast main external diameter coordinates with the unthreaded hole on cell body wall, and be communicated with the perforated pipe in cell body, on described cell body sidewall, be also provided with shore pipe, uniform battery lead plate support and the bellows of being connected with in described cell body, described battery lead plate support is separately installed with positive plate and negative plate, and the battery lead plate support that negative plate is installed coordinates with bellows, described bellows is sealing rectangular structure, two larger side faces of described bellows are cationic exchange membrane.
The beneficial effects of the utility model are, this low concentration heavy metal water film electrolytic processing apparatus, be applicable to process the heavy metal wastewater thereby under low consistency conditions, its advantage is: 1, adopt ion-exchange membrane, under the effect of DC electric field, the heavy metal ion in heavy metal wastewater thereby is carried out to separation; 2, the structure of application bellows, has increased the area of device inner membrance, thereby has reached the maximum area that heavy metal ion is passed through; 3, adopt pneumatic blending, waste water is mixed; Realize the cleaning of ion-exchange film surface pollution thing simultaneously, improve membrane flux.
