Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is treatment of dyeing wastewater reclaiming system structural representation of the present utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to accompanying drawing 1, a kind for the treatment of of dyeing wastewater reclaiming system, comprise catchment equalizing tank 1 and workshop reclaiming system, at the bottom of described equalizing tank 1 pond of catchmenting, be provided with boring aeration pipe and can carry out homogenizing and preoxidation to dyeing waste water, owing to containing more fiber in dyeing waste water, in order to remove floating matter larger in waste water, suspended substance, water pump and pipeline with protection rear end or setting are avoided wearing and tearing and stop up, before entering the equalizing tank 1 that catchments, mechanical grille well 2 is set, suspended substance in water and foreign material are cleared up, waste water after treatment enters into the equalizing tank 1 that catchments again, in the described equalizing tank 1 that catchments, be provided with sewage pump and pass through sewage pump ligation preliminary sedimentation tank 3, the described equalizing tank 1 that catchments is also connected with cooling tower 4 with reacting between preliminary sedimentation tank 3.Reaction preliminary sedimentation tank 3 tops connect pharmacy slot 5 by medicament pipe, reaction preliminary sedimentation tank 3 adopts siphon type pulse water device to connect hydrolysis acidification pool 6, then hydrolysis acidification pool 6 connects charcoal pond 7, described charcoal pond 7 is by contact-oxidation pool 8 connecting secondary settling tanks 9, described second-level settling pond 9 is provided with Sewage outlet, wherein, second-level settling pond 9 also connects workshop reclaiming system; Described system also comprises sludge thickener 10 and membrane compressor 11, and described sludge thickener 10 is connected with membrane compressor 11, and described sludge thickener 10 also connects respectively hydrolysis acidification pool 6, charcoal pond 7 and secondary sedimentation basins 9; Described workshop reclaiming system comprises the physico-chemical precipitation pond 12 that connects second-level settling pond 9, follow-up valveless water filter pond 13 and the sewage storage pool 14 of also connecting successively in described physico-chemical precipitation pond 12.
Dyeing waste water enters into by collection the equalizing tank that catchments; owing to containing more fiber in dyeing waste-water; in order to remove floating matter larger in waste water, suspended substance; with protection water pump and pipeline, avoid wearing and tearing and stop up; mechanical grille well is set before entering the equalizing tank that catchments; suspended substance in water and foreign material are cleared up, and waste water after treatment enters into the equalizing tank that catchments again, at equalizing tank, boring aeration pipe is set waste water is carried out to homogenizing and preoxidation.
Consider that waste water finally needs reuse, therefore front end is supporting, reaction preliminary sedimentation tank carries out colour of camel's hair pre-treatment to waste water, reaction preliminary sedimentation tank is processed and is adopted iron-based flocculating agent and lime coagulant aids to be used for removing the most of colourity of water, temperature need first pass through cooling tower high season, through materialization processed waste water, gravity flow enters into hydrolysis acidification pool, hydrolytic tank adopts siphon type pulse water device to carry out water distribution, because siphon type pulse water device can reach the effect of pulse in the short period of time, stir the mud at the bottom of pond, it is constantly fully mixed with sewage in pond, organism in anerobe and sewage obtains sufficient contact reacts.By acidication, make the macromolecular substance dissolving in water become small molecules, significantly improve the biochemical of waste water, acidication water outlet is flow automatically and is entered charcoal pond.
In charcoal pond, add Powdered Activated Carbon, form a certain proportion of mix suspending solid, owing to considering the anxiety in on-the-spot place, in biological carbon pond, adopt pure oxygen aeration pattern, the feature of pure oxygen aeration is exactly that processing efficiency is apparently higher than air method, by same sewage disposal, to same level, the required aeration time of oxygen method is generally only 1/3 left and right of air method.This is because the concentration of pure oxygen is 4.7 times of oxygen concn in air (21%), therefore the dividing potential drop of oxygen in oxygen method system, that is the impellent of dissolved oxygen, also higher 4.7 times than air method, at the saturation value CS of oxygen in water, also increased by 4.7 times, rate of oxygenation has also increased by 4.7 times, has significantly improved the transfer rate of oxygen, thereby the concentration of aerobic microbiological and activity are all improved, obviously improved the deficiency of traditional activated sludge process.By charcoal pond, water outlet enters into contact-oxidation pool again.
The removal of contact-oxidation pool strengthening to the hard-degraded substance of waste water and colourity, can resistance to overload shock, in the situation that changing greatly, water quality and quantity keeps relative stablizing, thereby guarantee that effluent quality reaches predetermined treatment effect, contact-oxidation pool water outlet gravity flow enters into secondary sedimentation basins and realizes mud-water separation, in pond, sludge part is back to reaction preliminary sedimentation tank front end, to supplement the sludge concentration in pond, secondary sedimentation basins water outlet enters into workshop reclaiming system and processes reuse, and secondary sedimentation basins part water outlet meeting standard discharge.
The sludge part of secondary sedimentation basins is back to hydrolysis acidification pool and charcoal pond, to supplement the sludge concentration in those ponds, excess sludge drains into sludge thickener, the mud of reaction preliminary sedimentation tank drains into sludge thickener by mud discharging system by mud, after gravity concentration, mud is sent by pumping to diaphragm filter press and carries out processed.
Comprehensive above-mentioned structure of the present utility model and principle are known, treatment of dyeing wastewater reclaiming system of the present utility model, solved the treatment system of printing and dyeing in prior art for some complicated components, large dyeing waste water, the alkali decrement waste water of decolouring difficulty, also be difficult to accomplish qualified discharge, process the problems such as recovery utilization rate is low, avoided the technical matters of dyeing waste water to the waste of the pollution of environment and water resources.
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 modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
