By accompanying drawing as can be known, the present invention includes sedimentation and filtration ditch, clean water basin 8, aerobic biochemical pond, equalizing tank 7, air-floating apparatus 9, sludge concentration device 10, wherein sedimentation and filtration ditch comprises one-level sedimentation and filtration ditch 1, two-stage precipitation filtering basin 2, the aerobic biochemical pond comprises one section Aerobic Pond 4 and two sections Aerobic Ponds 5, establish 1, two section Aerobic Pond 5 one side of one-level sedimentation and filtration ditch between one section Aerobic Pond 4 and the two sections Aerobic Ponds 5 and establish two-stage precipitation filtering basin 2; Clean water basin 6 connect aerobic biochemistry pool and air-floating apparatus 9; Equalizing tank 7 connects air-floating apparatus 9 and sludge concentration device 10.
One-level sedimentation and filtration ditch 1 of the present invention and two-stage precipitation filtering basin 2 connect sludge pump 11 for awl bucket spoil disposal structure at the bottom of the pond.Comprise with pipe connection roots blower 12, by roots blower air blast oxygen supply in described one section Aerobic Pond 4 and two sections Aerobic Ponds 5.Described clean water basin 8 comprise reuse water pump 13, are used for connecting the splicer reuse, and reuse water pump 13 is provided with switch valve, and clean water basin 8 are connected to the aerobic biochemical pond.The floating device 9 of described vapour comprises dregs scraper 14, air dissolved pump 15, flocculation agent dispenser 16, coagulant aids dispenser 17, wherein dregs scraper 14 is located at the top of air-floating apparatus 9, air dissolved pump 15 is located at the bottom of air-floating apparatus 9, and flocculation agent dispenser 16 is connected air-floating apparatus 9 and sludge concentration device 10 with coagulant aids dispenser 17.Described sludge concentration device 10 comprises mud concentration tank 18 and sludge dewatering equipment 19, and clear water output is established on mud concentration tank top, and the bottom is established the thickened sludge outlet and connected sludge dewatering equipment 19.Described equalizing tank 7 adopts the form of upward flow sedimentation and filtration, is awl bucket spoil disposal structure at the bottom of the pond, and workshop waste water enters from top, and the bottom connects sludge pump 11.
Technological process of the present invention and principle:
The waste water of production plant discharging of the present invention is all measured homogeneous through oblique net of 200 purposes or the laggard equalizing tank of taper net wheel receipts slurry, and by promoting the pumping shallow air-floatation, equalizing tank also plays the effect of preliminary sedimentation then, and sedimentary mud regularly send concentration basin by sludge pump.The shallow air-floatation technical equipment is used for the floc sedimentation that separating suspension and dosing are separated out.Shallow air-floatation is a kind of advanced person's of reasonable utilization " shallow pool theory " and " zero velocity " principle a quick airfloat equipment, only needs about 3 seconds, and the molten gas concentration of the dissolved air water of its outlet reaches theoretical maximum, and the more common air supporting of molten gas efficient doubles.Because its water-distributing device advanced person can be full for the treatment of pond by ten minutes equably with the full and uniform blended bubble of sewage in advance, nothing " dead band ", " inhomogeneous district ", thus greatly improved purification rate, to paper waste middle section water CODC
CrClearance 60-70%, SS clearance 80%.The catalytic oxidation technology is a kind of aerobic biological film method technology.Be provided with filler in the contact-oxidation pool, the part microorganism grows in filling surface with biomembranous form set, and part then is that cotton-shaped suspension growth is in water.Therefore it has the two characteristics of activated sludge process and biological filter concurrently.
Contact-oxidation pool is established two sections, utilizes the life habit of microorganism to cultivate multiple class dominant microflora, finishes the efficient removal to organic pollutant.Microorganic adhesion bed (filler) is set in each section increases kind and the quantity of microorganism.By filler the bubble that rises is sheared simultaneously, the specific surface area that increases bubble improves oxygen transfer rate.Contact oxidation method is to pollution load BOD
5The sewage that is lower than 30mg/L still has high clearance, and other aerobic process but is difficult to accomplish.The residuum of contact oxidation method is biological demoulding, so sludge output is very low, and surplus sludge volume is less, and dehydration property is good, can reduce the sludge treatment cost.
Mixed solution gravity flow after aerobic enters second pond and carries out the separation of mud liquid, finish denitrification process by returned sluge, the gravity flow of post precipitation supernatant liquor enters clean water basin, and mud is back to the acidication import to improve removal effect by air-lift device, and excess sludge send water extracter to handle.
Clean water basin are actually the water reservoir of enterprise's water of productive use, and the clear water after the processing is directly mended production system by topping-up pump and used.For guaranteeing paper machine quality, behind clean water basin, establish heavy filter tank.Heavy filter tank is designed to the upward flow slag and filters soon, and hybrid reaction dosing facility is housed, and adds flocculation agent and coagulant aids in right amount.Its process characteristic is the filtration velocity height, and water outlet SS content is lower, and filtrate (slag) enterprise can be self-supporting, need not back flushing, and effluent quality is good, and construction is low with running cost, and heavy filter back water quality can satisfy the requirement of paper machine water.Filter back clear liquid is an emission compliance water, and gravity flow enters also paper supply machine use of clear water, residue discharging.
Embodiment of the present invention only is the description that preferred implementation of the present invention is carried out; be not that design of the present invention and scope are limited; do not breaking away under the preceding topic of design philosophy of the present invention; engineering technical personnel make technical scheme of the present invention in this area various modification and improvement; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection all is documented in claims.
