Description
Technical field
The invention belongs to Industrial Waste Water Treatments field of purification, be specifically related to heavy-metal ion removal equipment and minimizing technology thereof in a kind of trade effluent.
Background technology
Along with discharge of industrial wastes amount sharply increases, plurality of heavy metal pollutant are discharged in living environment. Under certain condition, some heavy metal (such as hydrargyrum) can also be converted into the organic substance that toxicity is bigger under the effect of certain micro-organisms. It addition, toxic heavy metal can extended stationary periods with accumulation in the environment, be enriched with step by step by food chain, eventually enter into human body, make baby be injured even with heredity or breast milk, main manifestations is for being enriched in some organ of human body formation chronic poisoning. Therefore, the treatment technology of heavy metal contaminants becomes the focus of a research, and its achievement has major and immediate significance.
Heavy metal contaminants all has distribution in the systems such as big gas and water, deposit, soil, plant, and the existence form in different systems is different. Heavy metal existence form in soil, heavy metal pollution of soil are mainly due to using mud and what sewage irrigation caused, and in sewage, industrial wastewater accounts for 60%～80%, and complicated component, contain the heavy metal that biology is difficult to degrade all in various degree.
In recent years, the background value of the Changjiang river Heavy Metals in Water Environment has been carried out more deep investigation by the Chinese Academy of Sciences etc., result shows that in river, most elements mainly exists with particle state, and it is relatively low to dissolve heavy metal concentration partly, and the element that total amount is higher is also more high with the ratio that particle state exists. This feature and area condition have close ties, and when geographical air slaking are strong, suspended matter content directly affects concentration of element distribution in water environment. Meanwhile, chemical weathering is faint makes element be difficult to discharge, and river alkalescence is on the low side more makes the dissolved heavy metal concentration on the low side.
Entering the heavy metal of water environment by all means, the overwhelming majority, with the carrying out of physics, chemistry, biology and physics chemical action, is quickly transferred in deposit or is transferred in deposit by float. Heavy Metal In Sediments occurrence status and being characterized as: Pb mainly trends towards same Fe/Mn hydrous oxide, carbonate facics combines, and Cu primarily forms residue phase and organic phase, and Zn easily combines with Fe/Mn hydrous oxide, carbonate facics; Pb, Zn are with non-residue for main component, and Cu is with residue for main component.
Prior art and deficiency thereof
The method of heavy metal containing wastewater treatment has a lot, can be divided into two big classes: a class is to make deliquescent heavy metal be changed into insoluble or indissoluble metallic compound, thus it being removed from water. Another kind of is carry out concentrating and separating when not changing Chemical Forms of Heavy Metals, for instance hyperfiltration, electroosmose process, ion exchange, evaporation concentration method etc.
1, hydroxide precipitation method. The method is by adding alkaline precipitating agent (such as lime cream, sodium carbonate liquid caustic soda etc.) to heavy metal wastewater thereby, makes metal ion and hydroxyl reaction, generates the precipitate metal hydroxides of indissoluble, thus the method separated.
2, sulphide precipitation. The method is by adding vulcanizing agent in waste water, makes metal ion react with sulfide, generates the metal sulfide precipitation of indissoluble thus the method that separated. Vulcanizing agent can adopt sodium sulfide, hydrogen sulfide or Iron sulfuret. etc. The shortcoming of this method is that sulfide price is too high.
3, reducing process. The method is by adding reducing agent in waste water, and making reducing metal ions is metal or low valence metal ion, then feeding lime becomes precipitate metal hydroxides thus the method that separated. Reducing process can be used for the recovery of the metal ion such as copper, hydrargyrum, is usually used in the process of lead waste water.
4, ion exchange. Ion exchange is to utilize from the cation exchange groups of exchanger, swaps reaction with the metal ion in waste water, metal ion is replaced the method removed on exchanger. Heavy metal wastewater thereby is processed, such as Cu by ion exchange2+、Zn2+、Cd2+Deng, it is possible to adopt cation exchange resin; And with anionic form exist metal ion complex or acid group (HgCl2-、Cr2O7Deng), then need to be removed with anion exchange resin.
5, ferrite process. The oxide that ferrite is made up of iron ion, oxonium ion and other metal ion, is that one has ferromagnetic quasiconductor. Adopting Ferrite Methods for Treatment of Heavy Metals Waste Water is according to ferritic manufacturing theory, utilizes ferrite to react, the bivalence in waste water or trivalent metal ion, is filled in the lattice of ferrospinel, thus the method being precipitated separation.
6, electrolysis. Electrolysis is the method utilizing electrode and heavy metal ion generation electrochemical action and eliminating its toxicity. Different according to anode type, electrolysis is divided into electrodeposit method and reclaims heavy metal electrolysis two class. The shortcoming of this method is that power consumption is big, effluent quality is poor, wastewater treatment capacity is little.
7, membrane separating method. The method is to utilize a kind of special semipermeable membrane, under the effect of ambient pressure, is not changing in solution on the basis of chemical form, the method that solvent and solute are easily separated or are concentrated. Membrane separation process includes hyperfiltration, electroosmose process, diffusive dialysis method, liquid-film method and ultrafiltration etc.
8, absorption method. The method is the method utilizing adsorbent the heavy metal ion in waste water to be removed, but the shortcoming of this method is that adsorbent price is prohibitively expensive.
The shortcomings such as under prior art conditions, the increase processing the equipment construction cost of heavy industries sewage and operating cost will become inevitable, and existing traditional handicraft, that processing method has technological process is long, control complexity, take up an area big, processing cost height.
