Description
Technical field:
The present invention relates to remove the treatment unit of COD, grease, colloidalmaterial and suspended solid (SS) in industry and the municipal effluent.
Background technology:
Air supporting is to utilize the microbubble of the air generation that enters in the water attached to forming the dirty mixture of gas on the pre-treatment pollutent, between dirty mixture of gas and the liquid because the imbalance of density, produce buoyancy, reach a kind of water technology of purifying waste water thereby take pollutent to water surface removal; Air supporting is a kind of solid-liquid separation technique fast and efficiently.In recent years, be able to a large amount of uses at water treatment field, it can replace precipitation, clarification process in the water treatment, and especially to the removal of those frivolous flcos, effect is more obvious.More advanced air-floated water treating apparatus is a CAF cavitation air flotation device at present, its structural principle as shown in Figure 1, this product is the product of being developed by american wheat king eco-friendly power source group, it is by pond body 1, water-in 2, air flotation turbo 3, slag-treating machine 4, worm conveyor 5 and water outlet 6 are formed, left side at pond body 1 inner chamber is provided with left clapboard 11, form zone of action 13, be provided with right clapboard 12 on the right side, form treatment zone between left clapboard 11 and the right clapboard 12, slag-treating machine 4 is arranged on the upper end of treatment zone, be fixed on the pond body 1, worm conveyor 5 is installed in the right side of slag-treating machine 4, its effect is that slag-treating machine 4 is drawn together the dirty slag output that ejects, and treated district treated water then overflows from right clapboard, discharges from water outlet 6.This waste disposal plant is simple in structure, and Operation and maintenance are very easy to, and in industry have a wide range of applications at present.But this air-floated water treating apparatus can only be used for the pre-treatment of sewage, can not handle comparatively completely sewage separately, and it can't replace sedimentation processing technology fully, and use range is subjected to bigger restriction.
Summary of the invention:
The purpose of this invention is to provide a kind of air-floated water treating apparatus, it is to the improvement of CAF air flotation turbo and perfect, is special in removing the treatment unit of COD, grease, colloidalmaterial and suspended solid (SS) in industry and the municipal effluent.
The technical scheme that the present invention takes is:
A kind of air-floated water treating apparatus, comprise pond body 1, water-in 2, air flotation turbo 3, slag-treating machine 4, worm conveyor 5 and water outlet 6, left side at pond body 1 inner chamber is provided with left clapboard 11, and left clapboard 11 forms zone of action 13 with the left end of pond body 1, and air flotation turbo 3 is installed in the zone of action 13; Be provided with right clapboard 12 on the right side, be treatment zone between left clapboard 11 and the right clapboard 12, slag-treating machine 4 is arranged on the upper end of treatment zone, and be fixed on the pond body 1, worm conveyor 5 is installed in the right side of slag-treating machine 4, and water outlet 6 is arranged on the bottom righthand side of pond body 1, it is characterized in that: set up mixing section 8 at the left end of pond body 1, water-in 2 is arranged on the left upper end of mixing section 8, and dosing mouth 9 is arranged on the upper end of mixing section 8; In treatment zone, be provided with and separate swash plate 14 and sludge hopper 15, sludge hopper 15 is arranged on the below of separating swash plate 14, form pool 16 between right-hand member that separates swash plate 14 and right clapboard 12, the bottom of the bottom of air flotation turbo 3 and exhalant region 16 is interlinked by return line 7.
Further, below separation swash plate 14, be provided with three sludge hoppers 15.
Treating processes and advantage are as follows:
Pending sewage is introduced into mixing section 8 from water-in 2, handle medicine (coagulating agent and coagulant aids) and add mixing section 8 from dosing mouth 9, sewage and liquid medicine are realized the short mix reaction by the helical flow path that is provided with in the mixing section 8, enter the zone of action 13 that air flotation turbo 3 is housed after the hybrid reaction, the pre-treatment pollutent 13 fully contacts with the defeated microbubbles that come of return line 7 in the zone of action, microbubble is attached to forming the dirty mixture of gas on the pre-treatment pollutent, take pollutent to the water surface, wherein the dirty mixture of the gas of the overwhelming majority rises to Ji Zhaqu rapidly, along with the rotation of slag scraper 4, scum silica frost is scraped to spiral slot and is sent; The dirty mixture of the gas that small part is broken because of bubble in the uphill process or effect such as self gravitation is sunk then drop to and separates on the swash plate 14, and the coalescent then sludge hopper 15 that enters is removed.Set up return line between exhalant region 16 and zone of action 13, because of forming a negative pressuren zone in the zone of return line in air flotation turbo 3 start-up courses, this suction function can make the water of exhalant region be back to the zone of action at the bottom of the pond, returns the air supporting section.This process has guaranteed that about 40% water refluxes and do not have under the situation of water inlet the air supporting section and still can carry out work.
The present invention has overcome the shortcoming of original Air-float separator, set up mixing section 8 at feed-water end, water-in 2 and dosing mouth 9 are arranged on the mixing section 8 simultaneously, make it to become sewage and liquid medicine short mix district, enter the zone of action after the mixing, in treatment zone, set up separation swash plate 14, below separation swash plate 14, a plurality of sludge hoppers 15 have been set up, recessed whirlpool air supporting machine 3 has been installed in zone of action 13, link to each other with return line 7 between exhalant region 16 and the zone of action 13, the water inlet and the liquid medicine mixing time of existing CAF air-float water treatment device were reduced in 5 seconds by original 15 minutes, and this mixing section and Air-float separator-body structure; Set up at the treatment zone of existing CAF Air-float separator and to have separated swash plate 14 in the same way, mud pellet throw out in the water is sunk in separating on the swash plate, import then in the sludge hopper 15, the clear water that enters exhalant region 16 flows out from water outlet 6, the sewage treatment capacity of this air-float water treatment device and the scope of being received all increase than existing C AF air-float water treatment device, can the solid-liquid separation task can be born separately separately as sewage main body treatment facility, and the water treatment system of the overwhelming majority can be applicable to; Bottom, swash plate disengaging zone is provided with the multibuchet mud collection area, saves the equipment integral height, improves sedimentation effect, gets rid of sedimentary mud fast.
The present invention's its Inlet and outlet water major control index under normal running (operation) conditions is:
Water inlet: oil-containing≤250mg/L, suspended substance≤500mg/L
Air supporting water outlet: oil-containing≤15mg/L, suspended substance≤20mg/L, COD clearance 60～80%.
As adopting two-stage air supporting, the index of then intaking can correspondingly improve.
