Background technology
Water resources has three kinds usually---surface water, underground water and municipal middle water.
Underground water and surface water mostly are drinking water sources, can directly use though underground water does not add process, but hardness is large, easy fouling, long-term drinking is harmful, make pure water with reverse osmosis process, due to useful being entirely filtered with harmful composition in water, long-term drinking is in the same old way unfavorable to human body; Surface water is by can be used as city tap-water source after dosing germicidal treatment, but traditional processing mode cannot tackle the pollution day by day at water source; Though middle water is advocated energetically be used for industrial circulating water, have that hardness is large and content of microorganisms high and many harm such as chlorine root etching apparatus, process means and processing cost limited, can not be fully used so far.
As the moisturizing water source of the recirculated water that process water rich and influential family adopts, surface water, underground water and municipal middle water all can use in principle, but certain technology need be adopted to process.
It is little that electro-adsorption water treatment method has investment, and operation and maintenance cost is low, water utilization rate advantages of higher.But the electro adsorption technology weak point adopted at present is also clearly: require high to flow, flow velocity, turbidity, unsuitable directly cycle for the treatment of water; Owing to adsorbing zwitterion simultaneously, need frequent discharge and recharge, water hardness reduces limited, increases electric desalination difficulty on the contrary; Because water treatment amount is limited, need drop into a large amount of carbon fiber electrodes and electric installation, operation and maintenance cost is higher; Quantity of wastewater effluent is comparatively large, waste water resource.
Summary of the invention
The problems such as the present invention is that deficiency, especially recirculated water hardness in order to solve existing electro-adsorption water treatment method are large, easily fouling, chlorine root are high, perishable, on the basis of electro-adsorption water treatment method, great innovation is made to the structure of equipment, has solved that ionic concn is high, the recirculated water problem of large discharge.
Isometrical many circle distributed electrical planar water treatment facilities comprise electric and mechanical two portions: electric part can provide the positive and negative electrode of 36 volts tradable low-voltage dc power supply; Mechanical part is the round tubular structure comprising multiple same size, adopt metallic substance to be made into, and home position places positive electrode; Equipment at least should comprise a unit for treating water composition; Specifically comprise as the positive electrode wire (003) connecting low-voltage dc power supply positive pole, positive electrode rod (002), negative potential cylinder (001), gate (006) and gate slot (005).
Isometrical many circle distributed electrical planar water treatment facilities at least comprise a unit for treating water, unit for treating water comprises a circular metal negative electrode cylinder (001) and a positively charged metal extremely rod (002), a positively charged metal extremely rod (002) is arranged in circular central position, each unit for treating water works alone, and does not disturb each other.
In normal work, the water-carrying section that the metal negative electrode cylinder (001) that pending water can flow through unit for treating water is formed, also can flow through the exterior slots between unit for treating water, the water body flowing through exterior slots between unit for treating water can not obtain the water treatment of electro-adsorption.
Pending water flow through unit for treating water positive electrode rod (002), water stream channel between negative potential cylinder (001), positively charged metal is rod (002) extremely, water body pending in metal negative electrode cylinder (001) and water stream channel forms current path, under the effect of galvanic current, calcium, magnesium ion flows to power cathode, make near its accumulating metals negative potential cylinder (001), define a very strong alkaline environment region, can accelerate to make carbonic acid gas soluble in water and calcium, magnesium ion generation chemical reaction, thus generate a large amount of calcium carbonate, magnesiumcarbonate precipitates, be adsorbed near negative electrode, make the calcium in water, magnesium ion reduces, reduce the hardness of water body, water quality is after treatment made to meet production requirement.
Under the effect of galvanic current, the chlorion contained in water can be become free chlorine or hypochlorous acid (OCL-) by electrolytic oxidation, can also play effect that is anticorrosion, sterilization.
A unit for treating water has certain water-carrying section and certain effective working length for water treatment, has corresponding water treatment capacity and water treatment quality.
The water yield of water treatment is relevant with water-carrying section, also relevant with the flow velocity in water-carrying section, and after determining the ability of water treatment, the relevant parameters according to canal for water conveyance can determine required water-carrying section; When the water treatment capacity of unit for treating water can not meet the demands, need to increase on water-carrying section to arrange corresponding unit for treating water; When the water treatment quality of unit for treating water can not meet the demands, need carrying out arranged in series unit for treating water along in water (flow) direction, the flexible arrangement of unit for treating water, different engineering of water treatment requirements can be met.
The increase of unit for treating water is relevant with the central position of isometrical many circle distributed electrical planar water treatment facilities, as will unit for treating water be increased, and should increase in batch successively from inside to outside.
Along the unit for treating water that the longitudinal serial of water (flow) direction is arranged, having identical section parameter should; Often organize unit for treating water and at least should have a pair water-in and water outlet gate, make the water body of unit for treating water inside after the water-in of unit for treating water and water outlet closing gate can be mutually isolated with outside water body.
The unit for treating water of normal work, intake-outlet gate all opens wide, and the water body in water stream channel, under the effect of low-voltage dc power supply, forms a large amount of calcium, magnesium ion near negative electrode, sedimentation gradually, be adsorbed in metal negative electrode cylinder (001), form the throw out of incrustation scale shape.
After water treating equipment run for some time, more incrustation scale shape throw out can be formed at metal negative electrode cylinder (001), carry out removing contamination having processed with regard to needs; Adopting the method put upside down of power positive cathode to be stripped down from negative pole board slot by incrustation scale is mixed in water, to be extracted into by the water containing incrustation scale to precipitate on the bank with water pump.
For ensureing the normal work of equipment, removing contamination and can divide into groups to carry out, once one or more groups unit for treating water group being processed.
When carrying out removing contamination process, need by the inlet gate of unit for treating water group and water outlet closing gate; Only need by water outlet closing gate during the process of falling pole, pilot circuit makes the positive and negative electrode of this group low-voltage dc power supply switch, under the driving of reversible circulation, the throw out be attached on metal negative electrode cylinder (001) comes off and enters in water, utilize the modes such as water pump sewage to be retracted to ground settling tank and carry out precipitation process, the primary water crossed through precipitation process after a few hours still can carry out recycle, improves the utilization ratio of water resources, accomplishes sewage zero-discharge.
