Description
Technical field
The utility model relates to field of Environment Protection, particularly relates to a kind of wastewater efficient treatment unit.
Background technology
In recent years, more and more higher for environmental requirement, proposes larger challenge for traditional sewage treatment process, and the demand simultaneously for novel treatment technology and process also grows with each passing day.For the process of industrial high purity water, high saliferous and low-concentration heavy metal ions, traditional technology generally adopts the process of electrodialysis mode, and electrodialyzer intermediate ion exchange membrane is under DC electric field effect. and in solution, ionogen has selective penetrated property.Namely positively charged ion can through anode membrane, and negatively charged ion can through cavity block.The compartment be made up of dividing plate and film, negatively charged ion anode direction in its light room migrates across cavity block and by the anode membrane detention in dense room in dense room, and positively charged ion then migrates across anode membrane to cathode direction and constantly increased by the solution strength of solution obtained in the dense room of desalination of the cavity block detention in dense room in dense room thus in light room thus reach desalination, purifications, the object that concentrates or refine.The dirt produced in electrodialysis unit operational process mainly contains three classes: the mainly calcium that (one) is produced by electrode reaction and polarization, the carbonate dirt of magnesium.(2) in dense water, the mainly calcium of slowly separating out because of supersaturation, the vitriol dirt of magnesium.(3) under DC electric field effect; charge species is at the settling on film surface; mainly organism, colloid and microorganism; in the face of above three class problems; prior art substantially can only by regular stop cleaning and at substantial chemical agent solve; and add chemical agent and not only increase Financial cost, also add time cost.
Therefore those skilled in the art are devoted to develop a kind of lower-cost wastewater efficient treatment system.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide a kind of lower-cost wastewater efficient treatment system.
For achieving the above object, the utility model provides a kind of wastewater efficient treatment unit, comprise electrodialysis unit, rectifier (1) and motorized valve (2), described electrodialysis unit comprises membrane stack group (3), the suction culvert (4) of membrane stack group (3), the dense water outlet pipeline (5) of membrane stack group (3) and the fresh water outlet pipeline (6) of membrane stack group (3), this membrane stack group (3) comprises the pole plate (3b) at multipair membrane stack (3a) and membrane stack (3a) two ends, and this pole plate (3b) is powered by power supply (7), and rectifier (1) in this power supply (7) and membrane stack group (3) is just connected to, between negative pole, the dense water outlet pipeline (5) of described membrane stack group (3) and the fresh water outlet pipeline (6) of membrane stack group (3) are equipped with motorized valve (2), this motorized valve (2) and rectifier (1) control by electric procedure auto-control cabinet (11).
Because polarization tie dirt great majority occur on the cavity block face of the dense room of electrodialysis unit, namely occur on the anode surface of cavity block, because dense room solution system is in alkalescence, meet the deposition condition of CaCO3, MgCO3, after polarity of electrode is switched, dense, light room correspondingly changes, and makes original settling dissolving on cavity block face, and has settling to generate on the another side of cavity block.Adopt the Sewage treatment systems of said structure, by rectifier, the pole plate of electrodialysis unit is carried out to the dipole inversion of timing, thus broken the formation condition of the dirty things such as CaCO3, just play self cleanup action.Same because frequent transitions polarity of electrode, exchange dense, freshwater room and broken mode of deposition, or making settling dissolve and discharge with current (dense water and pole water).This ensures that there the performance of film and electrode is steady in a long-term, thus guarantee the stable of ratio of desalinization and effluent quality.Because the flow direction that is dense, fresh-water system also will be changed during frequent pole, road, dense, freshwater room is exchanged, so current motorized valve controls simultaneously.Control motorized valve and rectifier by electric procedure auto-control cabinet simultaneously
The fresh water outlet pipeline (6) of the suction culvert (4) of described membrane stack group (3), the dense water outlet pipeline (5) of membrane stack group (3) and membrane stack group (3) is all connected with flow control valve (9) and under meter (10).
Dense water outlet pipeline (5) outlet of described membrane stack group (3) is linked in the suction culvert (4) of membrane stack group (3).Dense water system current are circulating, and a part of water yield discharge, the cyclic part water yield, at the dense water system of dense water pump advance people, mixes with former aqueous phase.
The beneficial effects of the utility model are: the utility model adopts automatic pouring electrode systems at regular intervals, positive and negative electrode polarity is switched mutually, play cleaning ion automatically and change the dirt handing over film and electrode surface to be formed, to guarantee that ratio of desalinization is steady in a long-term, greatly reduce Financial cost and time cost, also there is the features such as ratio of desalinization is stable simultaneously.
