Embodiment
Before selecting this advanced treatment of wastewater electro-adsorption demineralization system for use, at first by calculating sewage quantity, detecting sewage quality, clear and definite effluent quality requirement etc., to select appropriate pretreatment filter type and electro-adsorption demineralization type of modules etc.Wherein pretreatment filters can be according to pretreatment filters such as the different choice sand filtration that comes the water water yield and water quality, multi-medium filtering, fibre-ball filtrations; The electro-adsorption demineralization module then can be according to different choice single-stage module of coming the water water yield and Inlet and outlet water water quality or twin-stage module, and its desalination rate and the rate of recovery can be regulated at 75%～85%.
As shown in FIG., the shell of pretreatment filters 2 and middle water pot 3 form by carbon steel or Low Alloy Steel Plate processing and manufacturing, inside and outside be coated with antifouling paste; Security personnel's strainer 6 is formed by the stainless material processing and fabricating; The major parts electrode of electro-adsorption demineralization module 7 is made by carbon material, and assembles complete by support and shell; Supporting with it pre-treatment promotes water pump 1, electro-adsorption demineralization module working shaft 4, regeneration wash-water pump 5 and cleans facility 8 and all carry out supporting setting according to treatment scale and flow process; Wherein pre-treatment promotes water pump 1, pretreatment filters 2, intermediate water tank 3, electro-adsorption demineralization module working shaft 4, regeneration wash-water pump 5, security personnel's strainer 6 and cleans facility 8 and is installed on the basis that is formed by concrete casting, and electro-adsorption demineralization module 7 is installed on the general frame that is welded by carbon steel material; Come waterpipe and the middle process pipe that connects to adopt anticorrosion Welded Steel Pipe, in-duct installation; Pipe blow-through can adopt vinyl tube, and pipe support lays; For guaranteeing the normal operation of system, except that above facility, also need supporting electric autocontrol facility and other water tank, pipeline, valve etc.; Plane and elevation combination water flow path direction are optimized layout according to practical situation.
Above structures construction is finished, after being in place, equipment can carry out zero load test run, water-filling debugging and commencement of commercial operation, roughly process is: come sewage to promote water pump 1 through pre-treatment and send into pretreatment filters 2, the removal of macrobead suspended substance and floating matter in this finishes water, to guarantee the long-term continous-stable operation of follow-up electro-adsorption demineralization module, strainer water outlet band is compressed into into middle water pot 3, promote through security personnel's strainer 6 by electro-adsorption demineralization module working shaft 4 again and enter electro-adsorption demineralization module 7, before entering the electro-adsorption demineralization module, 6 pairs of pretreatment filters water outlets of security personnel's strainer carry out secondary filtration, will effectively remove protection electro-adsorption demineralization module through the pollutent of pretreatment filters; The strong brine that the electro-adsorption demineralization module produces in desalting process washes regeneration continuously by regeneration wash-water pump 5; And electro-adsorption demineralization module 7 is cleaned by cleaning facility behind the operation certain hour, to improve the operational efficiency of electro-adsorption demineralization module.
Electro-adsorption demineralization module 7 forms electrostatic field planar water intermediate ion by carbon dioxide process carbon electrode negative pole 11 and carbon dioxide process carbon electrode anodal 12, thereby realizes desalination, and can realize the cyclic regeneration of electro-adsorption demineralization module.
Do not add any medicament in the operational process of electro-adsorption demineralization module, operate fairly simplely, during system regeneration, need not acid-alkali regeneration, only need get final product with the discharge of electrode short circuit and with former water flushing.Its operational process roughly is divided into three steps: workflow, regeneration flow process and blowdown flow process.Workflow: come water to send into the electro-adsorption demineralization module by electro-adsorption demineralization module working shaft 4, deliquescent salt is adsorbed removal in the water, and saltiness and specific conductivity reduce in the water.The regeneration flow process: be exactly the strong brine backwash process of module, be used for the module that water flushing short circuit leaves standstill, make electrode regeneration, the water after the back flushing can be admitted to and store the pond, waits until next cycle blowdown flushing and uses.The blowdown process: its essence of blowdown process is the same with regeneration, it is a backwashing procedures of module, but have any different in the water source, what the blowdown process was used is the water that stores the pond, the dense water after promptly regenerating, and this is an effective water saving process, because do not reach capacity as yet through the dense water after the regeneration, so with the back dense water that the produces wash module once more of regenerating, just saved the water consumption in the flushing process, improved producing water ratio.
Though described embodiment of the present utility model in conjunction with the accompanying drawings, those of ordinary skill in the art can make various distortion or modification in the scope of described claim.
