The sewage treatment complete equipment provided by the utility model can ensure discharge after reaching standards under the condition of discordance in proportions of carbon, nitrogen and phosphorus and large change in water yield and is low in running cost.
Description
Technical field
The utility model relates to a kind of waste disposal plant, is specifically related to the sewage disposal suite of equipment for Expressway Service.
Background technology
Domestic sewage to Expressway Service takes to be equal to the treatment process of sanitary sewage at present, i.e. conventional adjusting+anaerobism+aerobic technical process.Generally take full underground structure, automatic operating, unmanned.The sewage of service area can belong to sanitary sewage in nature, and organic content is not high, and the biological nutrition source is abundanter, and biodegradability is good.But electricity has some self unique features:
1) the ammonia nitrogen total phosphorous is very high, and chemical requirement is relatively low, can cause two unfavorable factors, and the one, the ammonia nitrogen total phosphorus adopts biochemical process to be difficult to reach processing requirements; The 2nd, the ratio of carbon, nitrogen, phosphorus is very inharmonious, has a strong impact on biochemical treatment, unless add carbon source, but this can cause the increase of running cost.
2) during Holidays, sewage quantity obviously increases, and the anti impulsion load of biochemical system is limited.
3) Spring Festival, wastewater treatment efficiency descends, and the volume of the flow of passengers during spring transportation is maximum, thus form a sharp-pointed contradiction, the obvious grow of the unstable of sewage disposal.
Prior art proposes to take to increase the way of carbon source, namely as adding glucose in order to solve the anti-problem of transferring of carbon N∶P ratio, complex operation, main is that running cost is too high, and service area can't be born this expense usually, finally causes equipment progressively in paralyzed state.Therefore, conventional treatment process can't guarantee that technique in the normal operation of service area, more can not guarantee qualified discharge.Owing to often there is no city planting ductwork near service area, and emission request must improve in local Environmental Protection Agency, and contradiction highlights more.
Summary of the invention
Do not consider the characteristics of service area sewage for prior art, its treatment process does not accomplish to suit the remedy to the case, and the utility model proposes a kind of suite of equipment that is specific to Wastewater Treatment in Expressway Service Center according to speciality and the discharging rule of service area sewage.This equipment can guarantee that qualified discharge and running cost are low in the situation that the carbon N∶P ratio is inharmonious, the water yield changes greatly.
The technical solution adopted in the utility model is as follows:
The Wastewater Treatment in Expressway Service Center suite of equipment comprises successively the septic tank that connects, pump well, equalizing tank, integrated biochemical system, flocculation sedimentation system, cartridge filter, intermediate pool and MBR pond; A water pump all is set in described pump well, equalizing tank and intermediate pool; Described integrated biochemical system inside is provided with anaerobism filler, aerobic filler and blower fan; Described flocculation sedimentation system is furnished with administration system; In described cartridge filter, environment-friendly filler is housed; Described MBR is furnished with membrane module and Aeration fan in the pond; Described septic tank, pump well, equalizing tank, integrated biochemical system and intermediate pool are positioned over underground, and described flocculation sedimentation system, cartridge filter and MBR pond installation are on the ground.
The utility model has following some beneficial effect with respect to prior art: (1) total nitrogen total phosphorus removal effect is definite, existing processing effluent index can only reach the GB8978-1996 secondary standard, technology of the present utility model can reach one-level B standard, especially ammonia nitrogen, total phosphorus can reduce very low level.(2) because materilization freatment method is the main technique of removing the ammonia nitrogen total phosphorus, therefore do not worry the impact of low temperature in winter, do not worry the large Yin Suo of volume of the flow of passengers Holidays yet.(3) film processing effluent quality is good.(4) need not to increase carbon source, running cost is low.(5) existing similar engineering is all underground type, and operation inconvenience can't be accomplished fine-grained management.Suite of equipment of the present utility model carries out organic combination according to the characteristics of the unit of each, and being placed in of having is underground, and what have is placed on the ground, workable, guarantees that fully treatment effect reaches the expection requirement.
Description of drawings
Fig. 1 is sewage disposal suite of equipment structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1, at first sewage enter septic tank, and this pond is complete underground steel and concrete structure, builds its function according to the national standard drawing: remove the ight soil sediment, and tentatively sewage is carried out acidifying.Septic tank effluent enters pump well, and this well is complete underground steel and concrete structure, and a water pump is set, its function: at any time sewage suction equalizing tank.Equalizing tank is complete underground steel and concrete structure, and a water pump is set, its function: regulate water inlet pH value, concentration, temperature.Integrated biochemical system is complete underground steel and concrete structure, contain anaerobic treatment and aerobic treatment, it is the combination of traditional treatment method, its inside is provided with anaerobism filler, aerobic filler and is equipped with a cover blower fan, function: the organism to sewage carries out inorganicization processing, but water outlet can not reach national emission request.Flocculation sedimentation system is Steel structure equipment on the ground, a supporting cover administration system, function: sewage aerobic is processed contained a large amount of ammonia nitrogens in the mud that produces and sewage and total phosphorus is effectively removed.Cartridge filter is the ground type Steel structure equipment, and quartz sand and the active carbon filler of plurality of specifications is equipped with in the inside, function: remove remaining non-solubility organism and dissolved organic matter.Intermediate pool is the underground type steel and concrete structure, a supporting water pump, function: the transition pond of sewage.
The MBR pond is the ground type Steel structure equipment, at pond body positioned inside one cover Immersive hollow fiber membrane sheet (curtain type membrane), this film adopts external pressure type hollow fiber separatory membrane fiber to make, following characteristics are arranged: 1. membrane material is polypropylene, this mechanical property of materials is good, contamination resistance is strong, and easy cleaning is particularly suitable for sewage disposal.2. stable chemical performance, acid and alkali-resistance, anti-bacterial corrosion, long service life, generalized case can 〉=3 years.3. the aeration process that can utilize biochemistry pool cleans the membrane fiber surface, keeps stable water production rate.4. specific surface area, unit volume packing density are large, and the permeable amount of diaphragm is large.5. the film surface micropore is even, and rejection effect is higher than circular hole film.In addition, the microbial growth breeding is kept in the outside supporting Fans oxygen supply in this pond.Function: remove remaining organism, suspended substance, ammonia nitrogen, total phosphorus, guarantee the sewage qualified discharge.
The mud of septic tank regularly drags for clearly processing by municipal sector.The mud that flocculation sedimentation system produces enters sludge thickener, then enters the plate-and-frame filter press press filtration and becomes mud cake, and the unit that mud cake is transferred to qualification disposes.Leaching water is got back to into water collecting basin and is processed, does not have secondary pollution.
