Accompanying drawing explanation
Fig. 1 be in the utility model embodiment use system annexation block diagram.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, better to understand the utility model.
Electroplating waste water treatment system as described in Figure 1, comprise equalizing tank, equalizing tank is connected with lift pump, lift pump outlet is connected with reactive tank, be provided with settling bath in reactive tank, be provided with sand filtration and carbon filter system in settling bath, carbon filter system outlet is connected with ultrafiltration system, ultrafiltration system outlet is connected with reverse osmosis system, and reverse osmosis system outlet is connected with evaporator system.Be provided with swash plate in settling bath, swash plate top is provided with via hole.Be provided with quartz sand in Sand Filtration System, in carbon filter system, be provided with activated carbon filtration.Equalizing tank is provided with medicine system, and medicine system comprises dispensing groove and chemicals feed pump; Chemicals feed pump is arranged on equalizing tank box bottom, and dispensing slot is in equalizing tank top, and chemicals feed pump is connected with Controlling System by circuit, and the start and stop of chemicals feed pump are controlled by Controlling System.Reactive tank is provided with overflow port.
Said system specific works process is:
(1) waste water enters pond body by water inlet pipe, flows through the intake chamber be positioned in the middle of the body of pond downwards, is reflected, then enter swash plate by the water inlet water distribution mouth of the inside by flow deflector.Along with solution upwards flows, the solid particulate contained by it is just deposited on parallel type sloping plate component, then slips into the sludge bucket bottom the body of pond, in sludge bucket, is discharged after sludge condensation by sludge outlet.And its clear liquor leaves swash plate by the water outlet via hole at top flows out, then collected by adjustable water outlet weir flow, flowed out by rising pipe.Being make clear liquor by forming a pressure difference during braiding channel in the object of swash plate top design via hole, ensureing that between each swash plate, fluidized―bed furnace is even, thus whole area is all utilized.The reliability of such operation increases, and reduces the impact of solution fluidised form, also reduces the possibility of fouling alluvial.
(2) dissolved air flotation device is arrived from efficient inclined-plate clarifying basin water out.This device utilizes a large amount of microbubbles, makes the suspended substance in itself and water adhere to thus emerge, thus reach the technology of secondary solid-liquid separation technique
(3) sand filtration, carbon filter: sand filtration adopts quartz sand to be primary filtration media, and filtrate is homogeneous filtering material, the more traditional filtrate of particle is thinner, good filtration effect, and water outlet is more stable, avoids traditional filter tank because of the random layer problem of misoperation filtrate; Carbon filter is actual is activated carbon filtration.Primary attachment and the organism removed in water.Sand filtration, carbon filter are respectively equipped with back-purge system device interior and are provided with unique back-purge system and oil-sand separator, when backwash, sand filtration quartz sand filter media suspension rolling in making, filtrate becomes suspended state, backwash is more thorough, rinsed by big yield again, recover the filtration retention functions of quartz sand filter media.
(4) ultrafiltration membrance filter: ultrafiltration is a kind of screening process utilizing membrane separation technique, with the pressure difference of film both sides for motivating force, take ultra-filtration membrane as filtration medium, under pressure, when stoste flows through film surface, the many tiny micropore that ultrafiltration membrane surface gathers only allows water and small-molecule substance pass through and become permeate, the material that in stoste, volume is greater than film surface micropore footpath is then trapped within the liquid feeding side of film, become concentrated solution, thus realize the purification to stoste, isolation and identification.Ultrafiltration membrane filter device has back-purge system equally, and flush efficiency is high, and flushing cycle is long, has saved a large amount of wash waters.
(5) falling-film evaporator is under gravity and vacuum induced and airflow function, uniformly membranaceously flows from top to bottom.In flow process, heat vaporized by shell side heating medium, the steam produced and liquid phase enter the separate chamber of vaporizer jointly, vapour-liquid is through being fully separated, steam enters condenser condenses (single-action operation) or enters lower 1st effective evaporator as heating medium, thus realizing multiple-effect operation, liquid phase is then discharged by separate chamber.Its principal feature: material heated time is short, vaporization temperature low (evaporating under negative pressure state), is applicable to the evaporation concentration of heat-sensitive material; System can under automatic or manual condition handled easily, cleaning is easily, reliable.
Native system adopts Chemical Method for Waste Water of Electroplate.Technological principle is: throw alkali pump and throw between alkali tune waste water pH value 11-12, add calcium salt simultaneously, make the phosphate radical in waste water, Hypophosporous Acid, 50 root form calcium phosphate, calcium propionate precipitation.Add flocculation agent again, coagulant aids makes throw out in waste water form bulk suspended substance, carry out solid-liquid separation by efficient sloping-plate sedimentation equipment, supernatant liquor enters air-flotation system and carries out secondary solid-liquid separation.Because airfloat equipment is continuous processing technique, have small suspended particle in waste water unavoidably to flow out with current, further employing quartz sand filtration, charcoal absorption retain absorption waste water in suspended substance and organism, for better removing the small suspended substance in waste water, further employing ultra-filtration membrane membrane separation unit, from the solution that ultra-filtration membrane membrane sepn goes out, wherein as Treated sewage reusing, pus directly arrives evaporator system and cold Ling Shui waters and pours water to clear water.
The technical process of wastewater treatment: waste water lifting pump is promoted to electroplating wastewater reactive tank, throw alkali pump and add sodium hydroxide adjust ph, then by chemicals feed pump, calcium chloride is added in electroplating wastewater reactive tank, add flocculation agent simultaneously, coagulant aids, make the phosphate radical in waste water, Hypophosporous Acid, 50 root forms calcium phosphate, calcium propionate precipitates, waste water carries out solid-liquid separation through efficient sloping-plate sedimentation equipment, supernatant liquor after solid-liquid separation enters airfloat equipment, carry out secondary solid-liquid separating equipment, for making solid-liquid separation effect better, need in waste water to add molysite, flocculation agent, coagulant aids carries out coagulating.Waste water is after air supporting after sand filtration, carbon filter pre-treatment, then by ultrafiltration membrance filter, from the solution that ultra-filtration membrane membrane sepn goes out, wherein as Treated sewage reusing, pus directly arrives evaporator system and cold Ling Shui and waters and pour water clear water.
The above is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications are also considered as protection domain of the present utility model.
