Description

A kind of blodisc integrated domestic sewage treatment device
Technical field
The invention belongs to domestic sewage treatment device technical field.
Background technology
At present, wastewater treatment in China rate is low, pollutant discharge amount is large, causes water pollution serious, and the eutrophication of water body is particularly outstanding.The environmental quality that State Environmental Protection Administration announces shows, although the pollution situation in the important water system of China and lake takes a turn for the better to some extent, situation is sternness still.
Along with the continuous increase of economic fast development and urban population, especially Small Urban is developing faster, and sewage work does not catch up with the needs of development, causes a large amount of sewage not obtain processing completely and just enters water body, more accelerates the process of body eutrophication.Therefore how solving sanitary sewage, controlling body eutrophication is the task of top priority.
Blodisc is a kind of biomembrance process wastewater processing technology, tank and the rotation disk body being partially submerged in sewage, consists of, and the microbial film of disc surfaces growth contacts sewage and the airborne oxygen in tank repeatedly, and sewage is purified.Existing blodisc rotor forms side by side for being much parallel to the disc of axle, has the shortcoming of short stream, in addition simultaneously, blodisc difficult processing, cost is high, processing power is low and easily produce foul smell drawbacks limit this technology applying in China.
China has had some for blodisc, to propose improved innovation and creation and utility model patent technology at present, but owing to there is such or such problem, does not all fundamentally overcome the shortcoming of blodisc.
Summary of the invention
The object of this invention is to provide a kind of blodisc integrated sewage treating apparatus, solve small-sized sanitary sewage exhaust emission environmental problem, reduce the energy consumption that the unit water yield is processed water, reduce manual operation amount.
Blodisc integrated sewage treating apparatus of the present invention is comprised of equipment box, denitrification pond, biological processing unit, inclined tube second pond and mud storage pool.Described equipment box skeleton part is formed by carbon steel square tubes soldering, and equipment box wallboard is partly glass reinforced plastic, and casing is not containing lid.
A kind of preferred version as blodisc integrated sewage treating apparatus of the present invention, in described denitrification pond, 3 D elastic filler is housed, filler has huge specific surface area, filling surface many microorganisms that growing, and wherein a part is denitrifying bacterium.
As a kind of preferred version of blodisc integrated sewage treating apparatus of the present invention, described biological processing unit has adopted unique composite bio-chemical technology, can be under less energy-consumption condition efficient degradation pollutent.Whole biological processing unit is comprised of three grades of (three) rotating biological rotors, each rotating biological internal rotor adopts multi-stage biological rotating disk, on each rotating disk, be provided with again radial thin slice biozone in large quantities, biozone comprises bacterium, fungi, protista and artifact.
As a kind of preferred version of blodisc integrated sewage treating apparatus of the present invention, above described inclined tube second pond, be provided with yarn synthetic fibre filtering net, can filter suspended substance; Below inclined tube second pond, be provided with sludge pump, the mud of inclined tube second pond bottom settlings can be moved into mud storage pool.
As a kind of preferred version of blodisc integrated sewage treating apparatus of the present invention, described denitrification pond and mud storage pool bottom communicate, and the mud that whole treatment system produces is all stored in mud storage pool, facilitates us regularly to process.
Blodisc integrated sewage treating apparatus workflow of the present invention is, first sewage enter denitrification pond by water-in, after the sewage refluxing with biological processing unit mixes, by fully contacting with the bacterium on filler in denitrification pond, some nitrate that contain in sewage are reduced into nitrogen by the denitrifying bacterium on filler, thereby the excessive degraded to realizing sewage total nitrogen in atmosphere, and the impurity sedimentation such as some suspended substances in sewage and grit is to the bottom in denitrification pond, and flow into mud storage pool; Sewage through degraded flows into biological processing unit, under the drive of electric motor, three rotating biological rotor synchronous rotations, air (oxygen) enters by biological rotor case tapping, mix with sewage, oxygen, sewage, microorganism are in contact with one another effect, finally realize organic degraded in sewage; Ammonia nitrogen is nitrate and nitrite by microbial transformation under the state of aerobic, then is back to denitrification pond, by the denitrifying bacterium in denitrification pond, is reduced into nitrogen, also can regulate sewage peak load simultaneously; Simultaneously on rotating biological rotating disk biozone by sewage, washed away, remove aging microbial film, reach self-cleaning object; In the water of biological processing unit, contain and come off microbial film aging and flow into inclined tube second pond, at the bottom of precipitating these microbial films and sinking to inclined tube second pond, through sludge pump, be transplanted on mud storage pool; Sewage also contains part fine suspension after tube settling, is provided with yarn synthetic fibre filtering net above inclined tube second pond, can, by this part suspended substance removal, use clarification of water.Finally by crossing the water purifying, from water outlet, flow out.
