Description
Technical field
The utility model belongs to sewage treatment area, is specifically related to a kind of integrated wastewater recycling treatment system.
Background technology
First AB method technique developed by German professor BOHUKE.Aeration tank is divided into high underload two sections by this technique, respectively has independently precipitation and sludge recirculation system.High loading section (A section) residence time is about 20--40 minute, act as master with biological treatment, and incomplete oxidation reaction occurs simultaneously, and biology is mainly the bacterial flora of short generation, removes BOD and reaches more than 50%.B section is similar to conventional activated sludge method, and load is lower, and mud is longer for age.
AB method A section efficiency is very high, and has stronger surge capability.B section plays the water outlet effect of checking on, and Treatment Stability is better.For the sewage disposal of high density, AB method has fine suitability, and has a higher energy-saving benefit.Main processing structures in AB method technique has A section aeration tank, intermediate sedimentation pond, B section aeration tank and secondary sedimentation etc., does not usually establish primary sedimentation pond, with A section for coagulation system.A section and B section have sludge recirculation system only separately, therefore have microbial population unique separately, are conducive to the stable of system function.
But AB method sludge yield is comparatively large, and A section mud organic substance content is high, and the follow-up stabilization treatment of mud is necessary, by the certain investment of increase and expense.Therefore, a large amount of mud how effectively processing the generation of AB method become problem demanding prompt solution.
Utility model content
The utility model object is to provide a kind of integrated wastewater recycling treatment system, solves the problem needing to process a large amount of mud after existing AB method is disposed of sewage and cause cost to improve.
The technical solution of the utility model is: a kind of integrated wastewater recycling treatment system, comprise pretreatment pool, adsorption tank, first stage precipitation tank, aeration tank, second-level settling pond, sludge anaerobic fermentation vat, thermal power generation system, fertilizer packaging system, described pretreatment pool, adsorption tank, first stage precipitation tank, aeration tank, second-level settling pond connects successively, the sludge outlet of pretreatment pool, the sludge outlet of adsorption tank, the sludge outlet of first stage precipitation tank, the sludge outlet of aeration tank, the sludge outlet of second-level settling pond is all connected with sludge anaerobic fermentation vat, sludge anaerobic fermentation vat is connected with thermal power generation system and fertilizer packaging system respectively.
Further, the water outlet in described pretreatment pool is provided with the grid for floating matter in filter sewage.
Further, sludge agitator is provided with in described aeration tank.
Further, described aeration tank is made up of the anaerobism aeration tank of leading portion and the aerobic aeration pond of back segment.
Further, described sludge anaerobic fermentation vat has venting port, slag-drip opening, and thermal power generation system is connected with venting port, and fertilizer packaging system is connected with slag-drip opening.
Further, described fertilizer packaging system is made up of platen press machine and wrapping machine.
The operation logic for the treatment of system of the present utility model is: adopt AB method to process rear discharge to sewage, collect the mud that each processing section produces, the mud of collection is dropped into sludge anaerobic fermentation vat and carry out anaerobically fermenting generation biogas, the biogas of generation input thermal power generation system is generated electricity, residue after fermentation is carried out making fertilizer, residue contains a large amount of moisture, dewatered by platen press machine, carry out solid-liquid separation, by wrapping machine, liquid packaging is become liquid fertilizer, solids package becomes solid fertilizer.
The utility model compared with prior art tool has the following advantages:
The utility model carries out recycling by mud AB method being run to the generation of each stage, improves economic benefit, thus reduces processing cost.

Fig. 1 is structured flowchart of the present utility model.
Embodiment
Embodiment 1
A kind of integrated wastewater recycling treatment system, comprise pretreatment pool, adsorption tank, first stage precipitation tank, aeration tank, second-level settling pond, sludge anaerobic fermentation vat, thermal power generation system, fertilizer packaging system, described pretreatment pool, adsorption tank, first stage precipitation tank, aeration tank, second-level settling pond connects successively, the sludge outlet of pretreatment pool, the sludge outlet of adsorption tank, the sludge outlet of first stage precipitation tank, the sludge outlet of aeration tank, the sludge outlet of second-level settling pond is all connected with sludge anaerobic fermentation vat, sludge anaerobic fermentation vat is connected with thermal power generation system and fertilizer packaging system respectively.Water outlet in described pretreatment pool is provided with the grid for floating matter in filter sewage.Be provided with sludge agitator in described aeration tank, owing to stirring mud, prevent adsorption tank anoxic and produce foul smell.Described aeration tank is made up of the anaerobism aeration tank of leading portion and the aerobic aeration pond of back segment, and the sewage through first stage precipitation tank precipitation successively carries out anaerobic treatment and aerobic treatment, thus makes discharge water quality reaching standard.
Described sludge anaerobic fermentation vat has venting port, slag-drip opening, and thermal power generation system is connected with venting port, and fertilizer packaging system is connected with slag-drip opening.Described fertilizer packaging system is made up of platen press machine and wrapping machine.Collect the excessive mud of each stage generation, focus on sludge anaerobic fermentation vat and carry out anaerobically fermenting, the biogas of generation enters thermal power generation system by venting port and generates electricity, and remaining residue contains a large amount of inorganic salt, can be used as Fertilizer application.By platen press machine, residue is carried out solid-liquid separation, the liquid after separation and solid containing a large amount of inorganic salt, can be used as Fertilizer application.Respectively liquid and solid are carried out being packaged to be liquid fertilizer and solid fertilizer.
By above-mentioned process, substantially achieve the zero release of mud, effectively solve the problem that AB method is maximum, be i.e. the problem of lignin-sludge.
The above embodiment only have expressed the embodiment of the application, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the application's protection domain.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from technical scheme design, can also make some distortion and improvement, these all belong to the protection domain of the application.
