Description
Technical field
The utility model relates to technical field of sewage, particularly relates to the buried sewage treatment equipment that a kind of low noise sound pitch is integrated.
Background technology
Along with the quick propelling of modernization of the country process, life in the countryside level improves year by year, the sanitary sewage that every day produces increases than the water yield before 10 years, Pollutant levels increase equally, surmount the self-purification capacity of water body and soil nearby far away, eutrophication process is accelerated, and Rural Water Environment causes anxiety, and domestic sewage treatment is extremely urgent.
But domestic sewage in rural areas is difficult to enter municipal wastewater pipe network, carry out specialty sewage disposal up to standard after enter physical environment.Therefore the sanitary sewage produced in rural development sewage disposal process rural area is needed, process to the first discharge standard in first discharge standard in " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) or local sewage drainage standard, enter physical environment, to rural economy levels to a certain extent, planning have municipal wastewater pipe network and supporting construction of municipal effluent plant to debug rear access city planting ductwork.
Arable land growing tension can be used in current rural area, and residential area is crypto set more, and civil engineering condition is poor, so a kind of low noise, high integrated, that floor space is little integrated sewage treating apparatus need the device type of active development just.
Summary of the invention
For the existing sewage disposal device in rural area exist noise high, take up an area many, to install inconvenience defects, the utility model provide a kind of lower noise, occupation of land less, the buried sewage treatment equipment that easy for installation, treatment effect is good.
For achieving the above object, the utility model adopts following technical scheme:
The buried sewage treatment equipment that a kind of low noise sound pitch is integrated, comprise housing, anaerobic pond, anoxic pond, stair oxidation pond, secondary oxidation pond, MBR membrane cisterna, sludge sump is separated into successively in described housing, submerged water gas blower is installed bottom described anaerobic pond, in anaerobic pond, anoxic pond, stair oxidation pond, secondary oxidation pond, biological hanging filler is installed respectively, in MBR membrane cisterna, MBR membrane stack is installed.
Low-concentration organic wastewater enters anaerobic pond by lift pump or gravity flow, utilizes the effect of anerobe, organism is hydrolyzed, acidifying and methanation, removes the organism in waste water, and improves the biodegradability of sewage, be conducive to follow-up aerobic treatment; Water after anaerobic pond process flows into anoxic pond, builds the environment (dissolved oxygen is being less than 0.5) of anoxic, is beneficial to lack to support microorganism growth, and its effect is activated sludge absorption, degradation of organic substances.Usually the nitrite nitrogen in backflow mixed liquor and nitrate nitrogen are generated under the effect of denitrifying bacteria nitrogen release; Anoxic pond muddy water mixed solution flows into stair oxidation pond and secondary oxidation pond, and mixed solution flows through biological hanging filler with certain flow rate after oxygenation, and with biofilm contact, the active sludge acting in conjunction of microbial film and suspension, reaches the effect of purifying liquid waste; Secondary oxidation pond mixed solution flows into MBR membrane cisterna, and adopt MBR membrane cisterna to replace the second pond of traditional technology, the water outlet of MBR film is discharged to product water tank, then film standard water discharge discharge or as Treated sewage reusing.
MBR membrane module biological reaction tank is adopted to replace traditional secondary sedimentation basins, it is little that MBR membrane cisterna compares secondary sedimentation basins area occupied, muddy water can reach thorough separation, discharge water water quality is excellent, sludge concentration higher in biochemical system can be accomplished, microorganism culturing is quicker, and make whole system degradation effect of organic compound higher, denitrogenation dephosphorizing efficiency is higher.
The integration mode of integration makes equipment transport to well working-yard in factory-assembled can directly to install, and convenient operating maintenance, the advantage of large-scale production is had more than buried type integrated equipment in the past.
Submerged water gas blower is adopted to replace conventional roots blower and rotary type blower fan, prevent second time public hazards, reduce the noise that gas blower body produces, in running, submerged water gas blower is placed in water, therefore sound is refracted in water at the interface of air and water, and do not import in air, simultaneously water and cell wall also same refraction go back and reach the effect of the sound that goes out; Must not make defense against sound equipment, submerged water gas blower, because putting in what water, namely reaches the effect of the sound that goes out, Gu do not need separately to make sound break or soundproof factory building, gas blower is put in what tank simultaneously, does not take up room, so effectively can utilize space; Construct solid, practicality of feeling at ease, motor and body are direct type (not having the puzzlement of traditional adjustment belt), and motor and board itself close envelope with O type ring, the anxiety of absolutely not water inlet entirely; The design of submerged water gas blower can reduce the pressure of adverse current to rotor, relatively also can reduce the loss to the energy; The vibrations that blower wheel transmits reduce, and must extend bearing life and reach 20%.
As preferably, in described secondary oxidation pond, mixed-liquor return pump is set, mixed-liquor return pump be used for will the mixed-liquor return that flow through to anoxic pond.Through backflow, a nearly step improves the effect of process.
As preferably, the biological hanging filler being positioned at anaerobic pond is anaerobe filler, and the biological hanging filler being positioned at anoxic pond is anoxic biologic packing material, is positioned at stair oxidation pond, the biological hanging filler in secondary oxidation pond is aerobic biologic packing material.Conventional biologic packing material selection is enriched, and type is various, comprises semi soft packing, combined stuffing, elastic solid filler, suspension type filler etc.Adopt the distinctive filling system of biological contact oxidation process, active sludge is attached to filling surface, not with water flow, because microbial film is directly subject to the strong agitation of upstream, constantly updates, thus improves decontamination effect improving.Biological contact oxidation process have that the treatment time is short, volume is little, good purification, effluent quality are good and stablize, the advantage such as power consumption is little.
As preferably, described anaerobic pond, anoxic pond, stair oxidation pond, secondary oxidation all arrange aerating apparatus bottom pond.
As preferably, the top of described housing arranges multiple access hole.Conveniently overhaul.
The integrated buried sewage treatment equipment of a kind of low noise sound pitch of the present utility model is by the design of height integrated integration, easy for installation, can save floor occupying area, by arranging submerged water blower fan in anaerobic pond, not needing, defense against sound equipment is set in addition and greatly can reduce noise, traditional secondary sedimentation basins is replaced by MBR membrane module biological reaction tank, not only save floor space, also substantially increase the effect of sewage disposal, there is the advantage that noise is low, floor space is little, easy for installation, treatment effect is good.
