Description
Technical field
The utility model belongs to technical field for the treatment of of organic waste, is specifically related to a kind of organic wastewater treating system from front-end processing biological sludge.
Background technology
At present, treatment of Organic Wastewater often adopts the combination process flow process of pre-treatment+main body process+advanced treatment, and main body processing unit often adopts anaerobism (anoxic)+aerobic treatment process.In the process that organic waste water is processed, anaerobism excess sludge and aerobic excess sludge can be produced, in the past few decades, people are " the light mud of heavy water " always, in recent years, sludge treatment is taken seriously gradually, but be the process of end mostly, mud by wastewater treatment process generation collects and is stored in sludge thickener, then by device for dehydrating sladge waste as belt filter press, centrifuge or plate-and-frame filter press carry out processed, then transport outward disposal, the mode of disposal has landfill, burning or recycling treatment.Fig. 1 is current conventional treatment of Organic Wastewater (treatment scale 300m
3/ d, influent COD
cr=80000mg/L, water outlet COD
cr< 50mg/L) system architecture and main process schematic flow sheet.
There are the following problems for this sludge treatment flow process: 1) sludge yield is large, anaerobic reactor clearance is by 75%, aerobic reaction pond adopts blast aeration system, whole treatment system produces the mud cake 22.5 tons that water ratio is 80% every day, sludge yield is comparatively large, and moisture percentage in sewage sludge is high, and calorific value is low, and the disposal options of mud cake is burn in our factory, add larger burden to refuse burning system; 2) sludge handling process frowziness produces; 3) sludge treating system is more complicated, sludge treating system comprises fresh feed pump, sludge dewatering equipment, air compressor and supporting air source purification system thereof, dosing tempering system, electric control system, sludge dewatering machine room, mud transportation equipments etc., system complex, has higher requirement to operational administrative personnel quality.
Utility model content
For above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of organic wastewater treating system from front-end processing biological sludge avoiding occurring above-mentioned technological deficiency.
In order to realize above-mentioned utility model object, the technical solution adopted in the utility model is as follows:
A kind of organic wastewater treating system from front-end processing biological sludge, comprise equalizing tank, dosing chamber, anaerobic reactor, aerobic reaction pond and second pond, wherein, described equalizing tank, dosing chamber, anaerobic reactor are connected by pipeline successively with second pond, described anaerobic reactor is efficient anaeration in normal temperature reactor, is provided with BIO integrated sewage water mud treating plant in described aerobic reaction pond.
Further, water distributor and triphase separator is provided with in described anaerobic reactor.
Further, described BIO integrated sewage water mud treating plant comprises microorganism reactor and aerating apparatus.
The utility model produces mud unit to each and transforms, it is made not produce mud or only produce a small amount of mud, excess sludge outlet is arranged on bottom anaerobic reactor, arrange outward with the form of granule sludge, can be used as the seed sludge of other treatment plant's anaerobic reactor, thus eliminate sludge treating system, simplify system architecture, and considerable economic benefit can have been created.Anaerobic reactor of the present utility model is power saving unit, and be responsible for degraded water major part organism, aerobic unit adopts integration apparatus, and single device installation is only had an appointment 2.3kW, and system cloud gray model expense is low; Sewage treatment systems does not produce stink, and equipment noise is little, can not produce secondary pollution, can not impact surrounding enviroment.
Accompanying drawing explanation
Fig. 1 is structure and the main process schematic flow sheet of current conventional organic wastewater treating system;
Fig. 2 is system architecture of the present utility model and process flow diagram.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 2, a kind of organic wastewater treating system from front-end processing biological sludge, it is characterized in that, comprise equalizing tank, dosing chamber, anaerobic reactor, aerobic reaction pond and second pond, wherein, described equalizing tank, dosing chamber, anaerobic reactor are connected by pipeline successively with second pond, described anaerobic reactor is efficient anaeration in normal temperature reactor, be provided with water distributor and triphase separator in described anaerobic reactor, in described aerobic reaction pond, be provided with BIO integrated sewage water mud treating plant.Organic waste water is successively through equalizing tank, dosing chamber, anaerobic reactor, aerobic reaction pond and second pond, then to sterilize again after film process reuse, in this process, a small amount of excess sludge in second pond can be back to the dosing chamber before system, further clears up process.
Anaerobic reactor adopts efficient anaeration in normal temperature reactor, choose reasonable processing load, well-designed core component water distributor and triphase separator, and sewage temperature controls at 33 ~ 35 DEG C, and processing efficiency can be promoted to more than 85% by original 75%.Anaerobic reactor is power saving unit, eliminate most organism in sewage, alleviate the processing load of Aerobic Pond, and sludge yield is low, the sludge yield of organics removal only has 5%, and compared with removing COD sludge yield 60% with aerobic unit, anaerobic unit is 1/12 of aerobic unit, improve the processing efficiency of anaerobic reactor, sludge reduction can be realized from source.
BIO integrated sewage water mud treating plant be a kind of by microorganism reactor with aerating apparatus group to all-in-one-piece revolutionary character innovative means, for suspension type equipment, install simple and convenient, be specially adapted to organic waste water, have efficient, low consumption, the features such as operational administrative is simple and convenient, it can dispose of sewage and mud simultaneously, the determination of number of devices, need according to sewage BOD in Aerobic Pond
5content and single device processing power are determined.This equipment, while improvement sewage, removes mud, removes the stench in pond and algae, and cleaning effect is firm for a long time, can eliminate stink (temperature is within 12-40 degree Celsius) in 3-7 days.
A small amount of excess sludge of second pond can be back to the dosing chamber before system, further clears up process.Whole system without the need to installing sludge treatment device, thus has simplified system architecture, and unnecessary mud is discharged with the form of granule sludge bottom anaerobic reactor, and granule sludge can be for sale, thus can produce certain economic benefit.
The utility model produces mud unit to each and transforms, it is made not produce mud or only produce a small amount of mud, excess sludge outlet is arranged on bottom anaerobic reactor, arrange outward with the form of granule sludge, can be used as the seed sludge of other treatment plant's anaerobic reactor, thus eliminate sludge treating system, simplify system architecture, and considerable economic benefit can have been created.Anaerobic reactor of the present utility model is power saving unit, and be responsible for degraded water major part organism, aerobic unit adopts integration apparatus, and single device installation is only had an appointment 2.3kW, and system cloud gray model expense is low; Sewage treatment systems does not produce stink, and equipment noise is little, can not produce secondary pollution, can not impact surrounding enviroment.
The above embodiment only have expressed embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
