The utility model for the technical scheme that solves its technical problem and adopt is:
A kind of water color ink wastewater treatment equipment, according to wastewater treatment process be provided with successively equalizing tank, soon mix the pond, mix pond, pressure filter, reservoir, reaction tank, air flotation pool, two-stage A/O biochemical treatment system and settling tank slowly, pass through pipe connection between the adjacent pond, the pressing filtering liquid of described pressure filter enters described reservoir, and described air flotation pool is equipped with dissolved air release and slag scraper.
The utility model for the further technical scheme that solves its technical problem and adopt is:
Be preferably, according to wastewater treatment process, be provided with collecting tank before the described equalizing tank, described collecting tank and equalizing tank pass through pipe connection.
Be preferably, described pressure filter is chamber-type press filter.
Be preferably, described equalizing tank is interior according to aerator is arranged.
Be preferably, on described equalizing tank and the described fast pipeline that mixes between the pond and on the pipeline between described reservoir and the described reaction tank pump is installed all.
Be preferably, on the pipeline between described collecting tank and the described equalizing tank pump be installed.
Be preferably, the described fast pond of mixing is higher than the described pond of mixing slowly, and described reaction tank to described settling tank has height fall from high to low.
The beneficial effects of the utility model are: water color ink wastewater treatment equipment of the present utility model mainly is to handle water color ink waste water with " mix soon pond+mix slowly pond+pressure filter+air flotation pool+two-stage A/O biochemical treatment system " combination, has following advantage:
1, the utility model can satisfy the requirement of waste water decoloring, and can remove the organism more than 98%, handles water outlet and can satisfy the requirement of national sewage comprehensive emission standard (GB8978-1996) first discharge standard, realizes qualified discharge;
2, need not coagulative precipitation tank or acid precipitation pond, so construction investment is few, floor space is little;
3, do not have oxidation processing technique, reduced operating devices such as the pH meter of control reaction conditions and ORP meter, facility investment is few;
4, only need to regulate in the coagulation and filtration process pH to 8～9 of waste water, later operation need not to carry out pH and adjusts repeatedly, has therefore reduced dosing pump and day-to-day operation reagent consumption;
5, reduced ferrous sulfate (FeSO
4), hydrogen peroxide (H
2O
2) and sulfuric acid (H
2SO
4) wait medicament to add, above medicament is acid medicine, has also reduced the usage quantity of liquid caustic soda (NaOH) simultaneously, therefore can reduce the operation medicament expense greatly and use;
6, do not need to add a large amount of chemical agents, therefore limited to the increasing amount of the total dissolved solid of waste water, be conducive to the middle water reuse of waste water up to standard;
7, reduce oxidation processing technique, no longer added ferrous sulfate (FeSO
4), and the polymeric aluminium chlorohydroxide that adopts (PAC) amount ratio common process consumption is few, so the mud generation also can reduce significantly.

Fig. 1 is the principle schematic of the water color ink wastewater treatment equipment of the utility model embodiment.
Embodiment
Below by specific specific examples embodiment of the present utility model is described, those of ordinary skills understand advantage of the present utility model and effect easily by the content that this specification sheets discloses.
Embodiment: a kind of water color ink wastewater treatment equipment, be provided with collecting tank 1 successively according to wastewater treatment process, equalizing tank 2, the fast pond 3 of mixing, slowly mix pond 4, chamber-type press filter 5, reservoir 6, reaction tank 7, air flotation pool 8, two-stage A/O biochemical treatment system 9 and settling tank 10, pass through pipe connection between the adjacent pond, the pressing filtering liquid of described chamber-type press filter enters described reservoir, described air flotation pool is equipped with dissolved air release and slag scraper, described equalizing tank is interior according to aerator is arranged, on the pipeline between described collecting tank and the described equalizing tank, on described equalizing tank and the described fast pipeline that mixes between the pond and on the pipeline between described reservoir and the described reaction tank pump is installed all, the described fast pond of mixing is higher than the described pond of mixing slowly, and described reaction tank to described settling tank has height fall from high to low.
The step that the water color ink wastewater treatment equipment of use present embodiment carries out the water color ink wastewater treatment is as follows:
A, with the water color ink wastewater collection to collecting tank, the water color ink waste water in the collecting tank is pumped in the equalizing tank, waste water carries out aeration in equalizing tank; To pump into fast mixing in the pond through the water color ink waste water that equalizing tank water quality is mixed well, quantitatively add the coagulant polymeric aluminium chlorohydroxide (PAC) of 0.3～0.5g/L and stirring fast with mechanically actuated diaphragm metering pump, can when adding coagulating agent, add coagulant aids (as sodium hydroxide) simultaneously; Waste water enters slowly and to mix in the pond then, is adding flocculation agent polyacrylamide (PAM) under the stirring condition at a slow speed again, and organic contamination suspended particle such as the acrylic resin in the waste water and colloid are changed into macroscopic macrobead suspended substance.
B, will all squeeze into chamber-type press filter through the pretreated printing ink wastewater of steps A with pneumatic diaphragm pump, utilize canvas press cloth can hold back the ability of particle diameter particulate matter more than 30 microns, the macrobead suspended substance that reaction in the A step generates is all held back, the filter cloth permeate water is carried out subsequent disposal, and pressing filtering liquid enters reservoir.
C, the processing water after handling through step B contain dissolved organic matter and particle diameter and exist less than 30 microns colloid, make waste water still have certain colourity.Waste water in the reservoir is pumped in the reaction tank, in reaction tank, successively add a spot of coagulant polymeric aluminium chlorohydroxide (PAC) and flocculation agent polyacrylamide (PAM), the process of adding will stir, utilize the compression double electric layer of coagulating agent and flocculation agent, the precipitation net is caught and adsorption bridging mechanism, colloid less than 30 microns in the waste water is changed into the bigger suspended particle of particle diameter, and the micro-bubble and its adhesion that utilize dissolved air release in the air flotation pool to produce, form global density less than the buoyancy aid of water, thereby rely on buoyancy to float to the water surface, struck off by the slag scraper that is arranged on the water surface, thereby the colourity of making and COD are further removed.
In D, the waste water after step C handles, colourity has reached national sewage comprehensive emission standard (GB8978-1996) first discharge standard, mainly contains solvability organic pollutant (COD), it is carried out bio-oxidation handle.Bio-oxidation adopts two-stage A/O(aerobic/anaerobic) biochemical treatment system, can allow organism conversion back and forth in the microorganism growth environment of aerobic/anaerobic/aerobic/anaerobic in the waste water, avoid in the common process problem in the one-level A/O treatment process the problem includes: denitrification not thoroughly, the waste water denitrification produces in second pond mud scum problem, can in two-stage A/O biochemical treatment system, add nutritive salt according to the water quality needs in this process.
In the printing-ink waste water treatment engineering trial run of Kunshan package packing supplies company limited, stably reaching standard discharges the water color ink wastewater treatment equipment of present embodiment at present.Following table 1 is the change of water quality table before and after handling.
