Technical field
The utility model relates to a kind of buried sewage treatment equipment, relates in particular to a kind of efficient buried sewage treatment equipment of many uses; It is mainly used in the processing of the sanitary wastewaters such as the processing of the sanitary sewages such as hotel, school, residential quarters, motorway, railway and livestock source mill, fresh milk source mill.
Background technology
The buried sewage treatment equipment that generally adopts in the market adopts acidication-bio-contact oxidation-depositing technology mostly, and equipment is body structure, and the centre is divided into three lattice by dividing plate.The first lattice are for filling Packed hydrolysis acidification pool, and the effect in this pond is the small organic molecule that the larger molecular organics of difficult for biological degradation in the sewage is hydrolyzed to easy degraded, is beneficial to the carrying out of subsequent biological treatment; The second lattice are biological contact oxidation pond, fill filler in the pond, by gas blower aeration in the pond, make filling surface cover with microbial film through the effluent stream of aeration through filler grids, the organism removal that is degraded by microorganisms in sewage and the process that microbial film contacts; The 3rd lattice are settling tank, contain the microbial film and a small amount of suspended substance that come off in the water outlet of biological contact oxidation pond, and in settling tank, the microbial film that comes off and suspended substance are deposited at the bottom of the pond, discharge by spoil disposal, and clear water flows out by overflow weir, and sewage is purified.This apparatus and process is ripe, investment is less, of many uses, deeply is subjected to user's welcome.Recent years, along with the raising of country to environmental requirement, some local requirement is processed water outlet and is reached " urban wastewater treatment firm pollutant emission standard " GB18918-2002 one-level A standard, to satisfy the needs of environmental requirement or user's reuse, but because integration apparatus adopts traditional two stage biological treatment process, it processes water outlet can only reach GB18918-2002 one-level B standard, can't satisfy the requirement of environmental protection, these characteristics so that the use of integration apparatus be restricted.
The utility model content
Can not reach the deficiency of one-level A standard in order to overcome existing buried sewage treatment equipment, the utility model provides a kind of efficient buried sewage treatment equipment of many uses, it is good that this equipment is not only processed stable effluent quality, satisfy the requirement of sewage discharge and reuse, and cost and working cost are low, and management maintenance is simple and convenient.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
Efficient buried sewage treatment equipment of many uses, this equipment are body structure, and the centre is divided into three lattice by dividing plate; The first lattice are for filling Packed hydrolysis acidification pool; The second lattice are biological contact oxidation pond, fill filler in the pond, by gas blower aeration in the pond, make filling surface cover with microbial film through the effluent stream of aeration through filler grids, the organism removal that is degraded by microorganisms in sewage and the process that microbial film contacts; The 3rd lattice are settling tank, contain the microbial film and a small amount of suspended substance that come off in the water outlet of biological contact oxidation pond, and in settling tank, the microbial film that comes off and suspended substance are deposited at the bottom of the pond, discharge by spoil disposal, and clear water flows out by overflow weir, and sewage is purified; It is characterized in that behind existing settling tank, adding again a lattice casing, as filtering cloth filtering pool, be laid with the fiber filter disc in the filter tank, header, mobile mud system, the mud drainage slot inhaled.
In the utility model, described fiber filter disc is the ion fiber filter disc.This filter disc can be tackled the flco that absorption is not removed through settling tank in a large number, improves the solid-liquid separation capability of equipment, and effluent quality is improved, and stable water outlet is good.
In the utility model, described filter cloth has added wear-resisting brush ionic charge for can hold back the filter cloth specialized that particle diameter is micron-sized particle on this filter cloth specialized material structure.The shortcoming of having avoided conventional filter cloth that the surface charge coating is only arranged and having been washed away easily makes filter effect better, cleans cleaner thorough.
In the utility model, described filter cloth is located on the filter frame, and described header is located at outside the described filter frame, and it is excavating pump that the mud system is inhaled in described movement, also is provided with the flushing driving in the described filter tank.
In the utility model, described filter cloth is located at the bilateral of filter frame.
The ion fiber filtering cloth filtering pool designs by special construction, greatly increases filtration area, adopts the bilateral filtered model, can save the required space of filtering layer, supporting layer and water gathering system in conventional filter tank, filtration area is enlarged, greatly reduce floor space, the volume of integration apparatus is minimized; The ion fiber filtering cloth filtering pool adopts the mode of wire moving flushing, so that cleaning process and filtration procedure can carry out simultaneously, during filter cell rinse, adopt driving drive excavating pump to sweep as wire and wash, negative pressure-pumping is attached on the dirt on the filter disc, has saved the conventional backwashing equipments such as high powered water pump.
Generally, at the structure that keeps existing buried sewage treatment equipment, behind the settling tank of existing installation, add again a lattice casing, as the ion fiber filtering cloth filtering pool, lay fiber filter cloth in the filter tank, sewage self-flowing through precipitation process enters filtering cloth filtering pool, current filter by filter cloth from outside to inside from the filter disc both sides under pressure, tackled by filter cloth without the microbial film flco of settling tank removal and the suspended substance in the water, sewage is purified, sewage after the purification is collected by the rising pipe of the aperture in the filter frame and bottom, overflows into water outlet by effluent weir at last, realizes improving the purpose of effluent quality.Along with the carrying out of filtering, in the accumulation of filter cloth surface, filtration velocity reduces suspended substance gradually gradually, rises gradually in the pool inner water position.When water level rises to predetermined water level, begin to carry out the negative pressure-pumping back flushing, filter disc maintains static during back flushing, along with the movement of moving flushing driving and the startup of excavating pump, begin that the mud on the filter disc is carried out wire and sweep suction, the muddy water of sucking-off enters sludge sump by water pump, behind the mobile stroke of driving, filter cloth is cleaned totally, but system's fully automatic operation.
In sum, the beneficial effects of the utility model are:
(1) stable effluent quality is good, with this device processes sanitary sewage and with the trade effluent of sanitary sewage similar performance, need not to increase other treatment facilities, can make water outlet reach " urban wastewater treatment firm pollutant emission standard " GB18918-2002 one-level A standard, the scope of application is wider;
(2) device structure integrated design, simple compact, auxiliary facility is few, and all parts are compared with traditional civil engineering pond in workshop processing assembling, and construction is not subjected to weather effect, and the duration is short, and construction costs is low;
(3) equipment total installed capacity power is low, and working cost is low, and the back flushing water loss is few, inhales to wash water consumption rate less than 1%, and equipment can continuous filtration when back flushing, reduces filtration time, saves backwashing equipment, reduces the support equipment cost;
(4) the filter disc assembly in the filler in the biological contact oxidation pond and the ion fiber filtering cloth filtering pool adopts stdn, modular design, and setting accuracy is high, safeguards that replacing is simple and convenient, and extensibility is strong.
