Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Waste Water Treatment as shown in Figure 1, equalizing tank 1, screen cloth 2, coagulative precipitation tank 3, shallow layer flotation machine 4, anaerobic fixed film reactor 5, contact-oxidation pool 6 and second pond 7 that this Operation system setting has order to be connected, described coagulative precipitation tank 3, shallow layer flotation machine 4, contact-oxidation pool 6 and second pond 7 are all connected with sludge thickener 9, this sludge thickener 9 is connected with pressure mud machine 10, described screen cloth 2 is connected with stock tank 8, and described sludge thickener 9 is connected with described equalizing tank 1 with pressure mud machine 10.
Equalizing tank 1, for carrying out runoff investigation and water quality regulation, arranges 3 stirrers in this equalizing tank 1.Because paper industry is in the diversity of production process sewage discharge, makes the water quality of the sewage of discharge and the water yield have certain change in one day, therefore require to regulate sewage, balanced water quality, evenly can enter subsequent processing units, improve treatment effect.
Screen cloth 2 adopts waterpower screen cloth, and its mesh size is 60 orders, and the isolated paper-making fibre of screen cloth 2 and air-flotation scum enter in stock tank 8, are back to production with stock pump.The wool in waste water can effectively be removed and reclaim to screen cloth, the impurity such as cotton and man-made fiber, has simple, the advantages such as efficiently, do not add chemical agent, running cost is low, and floor space is little and easy to maintenance.
Coagulative precipitation tank 3 as shown in Figure 2 comprises reaction tank 301 and settling tank 302, be provided with in this reaction tank 301 with top the first dividing plate 314 in a distance and with bottom second partition 315 in a distance, described reaction tank 301 is divided into room I, room II and room III by this first dividing plate 314 and second partition 315, this room I is provided with water-in 311, is equipped with whipping appts in described room I, room II and room III; Described settling tank 302 is provided with baffle plate 321, described settling tank about 302 is divided into clear water zone A and settling region B by this baffle plate 321, the bottom of this settling region B is tapered and be provided with sludge outlet 323, this clear water zone A is provided with water outlet 322, described baffle plate 321 is provided with the some inclined tubes being communicated with clear water zone A and settling region B, this settling region B is connected with described room III, and described room I is provided with and adds flocculation agent device 312, and described room II is provided with and adds coagulant aids device 313.Sewage enters room I from water-in 311, add flocculation agent device 312 and add flocculation agent to room I, be condensed into floss through the suspended solids stirred in sewage and enter room II, add coagulant aids device 313 and add coagulant aids to room II, floss is grown further, room III is entered through stirring, stir further in room III, current, through turning back and stir for several times, promote particle flocculation, the residence time holds, and flocculating effect is good; After current enter settling region B, floss sinks under gravity, and clear water enters clear water zone A by inclined tube, and clear water is flowed into by water outlet 322 or water pump suction shallow layer flotation machine 4, sludge accumulation is bottom settling region B, and timing enters sludge thickener 9 from sludge outlet 23.
Shallow layer flotation machine 4 is advanced prior aries, change the pneumatically supported static state water inlet of tradition, dynamic water outlet is dynamically water inlet, static water outlet, namely when entering in air flotation pool containing the combined sewage with microbubble suspended particle, use stream device to move, it is zero that the horizontal flow velocity of composite waste goes out to flow device relatively, thus inhibit the turbulent flow in groove, thus stable dissolved air flotation (i.e. so-called " zero velocity principle ") can be carried out, flotation body lift velocity reaches or close to theoretical raising speed, drastically increase processing efficiency, the residence time of waste water in shallow gas floating trough is made to reduce to 3min by 30 traditional ~ 60min, and collection cohesion, skimming, draining, spoil disposal is integrated, it is a kind of wastewater treatment equipment efficiently.
The organism macromole of difficult for biological degradation is hydrolyzed into by anaerobic fixed film reactor 5 can biochemical degradable organism.Utilize returned sluge effectively to improve hydrolysis section concentration gradient, wastewater through organic matter can be good at degraded.Due within the different time periods, water quality is extremely uneven, and for ensureing the continuous operation of follow-up equipment, arrange diving mixer in pond, waste water is fully mixed, and homogeneous is all measured.
Contact-oxidation pool 6 makes sewage carry out oxidizing reaction, namely utilizes the air that gas blower provides, and is become by the organic substance decomposing in sewage carbonic acid gas and water also to breed the microorganism be attached on filler, thus reaches the object of process.
Second pond 7 adopts vertical sedimentation tank, sewage is utilized to flow into from settling tank pipe core, flow downward along pipe core, reflector through pipe core bottom is folded to top flowing, sewage is with the bottom-up flowing of flow velocity v, particle in sewage is with heavy fast u sedimentation, as u>v, particle starts to sink, during u=v in particle suspension sewage, during u<v, particle flows out with sewage, and the sewage prionodont V-notch weir overflow being located at settling tank surrounding rising to settling tank top enters water leg and discharges.
Sludge thickener 9 adopts perpendicular stream concentration basin, and pressure mud machine 10 adopts belt to press mud machine.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
