Description
Technical field
The present invention relates to a kind of industrial purifying device, specifically a kind of high-efficient metallurgical industry waste water purifying device.
Background technology
In century in 19th century to 20, in world industry process, steel and iron industry was once becoming one of industry of world's most growth, obtained swift and violent development.No matter at the output value, product structure, or industrial technology has had unprecedented raising.Enter 21 century, iron and steel remains the irreplaceable raw material of the mankind, is the important indicator of measurement national overall national strength and industrial level.Steel industry is use water rich and influential family, is again main environomental pollution source.Steel industry Wastewater Pollutant mainly contains: phenol, cyanide, petroleum-type, COD, suspension etc.Using water wisely, reducing blowdown, by the operating Mode of Circular Economy realizing minimizing, recycling, recirculation (3R) in water, is the more and more urgent task that the development of China's steel industry faces.
Do not have water stabilization measure in circulation, cause rate of water make-up large, displacement is large.Though there are the circulatory system and facility in present many enterprises, but its corresponding supplementing water and circulating water quality uncontrolled, lack again effective water stabilization measure, after making recirculated water use a period of time, suspension increases, and salt content increases, bacterium algae propagation etc., cause water quality can not meet user's requirement, moisturizing must be increased to reduce suspension and total salinity in recirculated water, thus cause rate of water make-up large.
Domestic steel-making wastewater treatment conventional method has flocculation sediment+filtration+sludge treating system.Wherein with regard to important pollutant SS(suspension) clearance analysis: by the level adding flocculant, flocculation aid postprecipitation water outlet ss suspended solid content can reach 150 ~ 200mg/L, 150 ~ 200mg/L can be reached by water outlet ss suspended solid content after improvement water inlet hydrocyclone and increase magnetic knockouts, have a long way to go, because this increasing filtration system with 50 mg/L reaching national water pollutions concentration of emission limit value at that time.Filter mainly uses double filtering filter tank (filtering velocity 5m/h), and along with development and the raising of domestic water treatment technology, filtering velocity can reach the gravity filtration of 10m/h or mechanical filter generally uses.
On 06 27th, 2012 national environmental protection portions and national quality supervision and inspection Quarantine Bureau have issued " steel and iron industry pollution discharge standard " (GB13456-2012), newly-built iron and steel enterprise Pollutant emission concentration limit value and the unit product base platoon water yield have had new requirement, water outlet ss suspended solid content 30mg/L, the unit product base platoon water yield is 0.1m
3/ t(makes steel).This improves further to the requirement of steel industry wastewater reduction, recycling, recirculation (3R).
Therefore adopt increase ion-exchanger to soften the waste water after filtration at present, reduce waste water hardness, the sludge quantity increased to reduce adding of milk of lime.After the method process of flocculation sediment+filtration+ion-exchange, mixing water can reach reuse standard like this.But in order to reduce the pollution of waste water to ion exchange resin, need to add chlorine dioxide, chemical feeding quantity will reach 2mg/L, regeneration of ion-exchange resin simultaneously can produce acidic and alkaline waste water, and it is 0.138 yuan/m that water softening system increases operating cost
3, also need to increase regenerative pump, regenerating unit etc., Waste Water Treatment floor space increases greatly, and hypervisor is more complicated, and investment improves greatly.
Summary of the invention
In order to overcome the shortcoming that prior art exists, for steel industry waste water characteristic, the invention provides a kind of life-span long, the efficient waste water purifying device that use cost is low.Key problem in technology of the present invention is: 1. adopt in single cover tank body and adopt 2 cover purification filter chambers, overcome the defect that common filtration backwash stops production; Purification filter chamber adopts center water inlet, and water inlet pipe is installed the energy dissipating of circular propagation cylinder, radiant type eddy flow water distribution, whole cyclone-flow water distribution is made up of steel plate or other high-abrasive materials.Waste water tangentially enters cylinder with the speed of 6m/s-10m/s, forms downward spiral vortex along wall.Weigh in efficient purifying device and large suspended particulate is thrown toward wall, and along wall slide downward under backspin water jet propulsion and Action of Gravity Field, finally form concentrate at the vertex of a cone and discharge continuously through underflow opening.Small and light suspended particulate is then rotated down with internal layer primary water and to a certain degree changes direction afterwards, forms secondary vortex flow.
2: mill run resistance is large, pressure drop large, the weakness of resistance to compression ageing resistace difference to adopt stainless steel spigot-and-socket filter cap to overcome, service life improves greatly, security performance is more reliable, integrated carrying ability is high, catchment effective, during backwash, water distribution is even, can not make filtrate unbalance stress and random layer or race are expected;
3. top, bottom (head) adopt rotary press modelling form intake pressure to increase, and filtering velocity improves greatly (20m/h); Particle diameter of filter medium reduces (0.5-1.0mm), and purifying efficiency improves greatly; Inlet and outlet water, backwash electrically operated valve, according to SECO, control purifying device by PLC and automatically run; All on-the-spot feedback signals are connected with control room PLC, can remote online operation supervise and control by HMI, carry out technical parameter setting, and realize fault alarm display, system reserves Ethernet interface, by network communication function, can realize data transmission.
4. can be used for outside steel industry wastewater treatment, also availablely extensively in electroplating wastewater, need in the Industrial Wastewater Treatment of deep layer purifying containing coal waste water, Metallurgical Waste Water, heavy metal wastewater thereby, power industry waste water etc., all should can make water outlet water quality reaching standard or reuse.
For realizing the object of the invention, provide following technical scheme: a kind of high-efficient metallurgical industry waste water purifying device, comprise tank body, the delivery port on tank body top, the drain of tank base, drain connects blow-down pipe, purification filter chamber is provided with in tank body, it is characterized in that described tank body center is provided with baffle for separating and becomes two the purification filter chambers in left and right, described left and right purification filter chamber is all arranged on porous plate, porous plate is provided with spigot-and-socket filter cap, filter material layer is provided with above porous plate, filter material layer is disposed with cobble bed course from the bottom up, one-level silica sand filter material layer and secondary silica sand filter material layer, left and right purification filter chamber is provided with independent cyclone-flow water distribution, cyclone-flow water distribution is arranged at purification filter chamber upper end, each cyclone-flow water distribution is all connected with a water inlet pipe and a backwash outlet pipe, purification filter chamber center, left and right is provided with and communicating pipe connects drain, described cyclone-flow water distribution comprises the cylinder that top cover is arranged at top, middle part is tapering transition section, bottom is the cylinder that Zhi Jing is greater than top, water inlet pipe is tangentially connected with top cylinder, backwash outlet pipe and bottom cylinder tangent.
