Compared with the prior art the present invention has following distinguishing feature and positively effect: the present invention is arranged on the car body of the below of sweeper foul water tank, take full advantage of the intrinsic space of environmental sanitation sweeper, rational deployment, the single that employing with the Sewage treatment systems of sectional type purpose ceramic-film filter significantly improves sweeper is washed and is swept the activity duration, reduce sweeper backhaul to add water and the sewage effluent time, the sweeper reduced in fundamental operation area is purchased and use cost.The employing of purpose ceramic-film filter mainly utilizes the cross flow filter principle of ceramic membrane, vitrified pipe gathers pore, during filtration, diameter is less than the partial impurities in pore aperture and part clear water can pass through pore, remaining most of impurity is then flushed to outside purpose ceramic-film filter by high velocity flow, the impurity flowed through in ceramic membrane can be made to be attached to ceramic membrane surface, keep good filter effect for a long time, filtration efficiency is high, and maintenance cost is low.
The purpose ceramic-film filter of sectional type adopts between multiple segment filters section by the fixing composition one of coupling device, compared to the monoblock type purpose ceramic-film filter of same length, while meeting filtering requirement, replacement charge when ceramic-film tube whole breakage and blocking can be reduced, be convenient to dismounting and maintenance, reduce use cost.
In foul water tank, set up liquid level sensor and set up valve in Sewage treatment systems; when the sewage in foul water tank can be made to reach liquid level sensor position; Sewage treatment systems starts automatically; easy to operate;, add the level of automation of system, when sewage is lower than liquid level sensor; Sewage treatment systems is closed automatically, can protect water pump and filtration unit.
Ceramic-film tube in purpose ceramic-film filter erects to be put with the tilting sewage that can effectively prevent through the precipitation of ceramic-film tube and blocking, and the lateral arrangement of ceramic-film tube can utilize the finite space of sweeper better.
The Seepage of sewage when the seal shock-proof device that between ceramic-film tube in the purpose ceramic-film filter of sectional type and the two ends of fillter section are provided with can effectively prevent from filtering, sealing device is rubber, silica gel elastomeric material, have the effect of damping concurrently, reduce the breakage that ceramic membrane produces because of vibrations.
Sectional type purpose ceramic-film filter is horizontal, oblique or longitudinally arrange and can carry out according to the finite space of sweeper the adjustment that cloth is set up, its decoration form is not limited to above-mentioned three kinds, can also laterally, longitudinally, oblique three kinds use simultaneously, on the basis in intrinsic space, farthest improve effective working length of purpose ceramic-film filter, longitudinally and oblique layout then effectively can prevent precipitation in strainer of rubbish in sewage and blocking.
The transverse uniaxial of sectional type ceramic membrane, laterally different axle, longitudinally coaxial, longitudinal different axle, oblique coaxial, oblique different axle all can adjust according to the finite space of sweeper, farthest improve effective working length of purpose ceramic-film filter.
Sectional type purpose ceramic-film filter shell adopts the corrosion resistant material such as stainless steel, macromolecular material and matrix material effectively can prevent purpose ceramic-film filter corrosion in use and oxidation, improves the work-ing life of purpose ceramic-film filter.
Every section of fillter section of sectional type purpose ceramic-film filter all arranges back flushing mouth, be convenient to utilize pressurized air and current to carry out counterflush to purpose ceramic-film filter, more effectively can remove the impurity be blocked in ceramic-film tube internal surface pore, high-pressure air is used to carry out back flushing by back flushing mouth to purpose ceramic-film filter, flush efficiency is high, and saves the water yield needed for cleaning; Use High-Pressure Water to carry out back flushing by back flushing mouth to purpose ceramic-film filter, flush efficiency is high, and the cleaning time length is more permanent, and cleaning performance is good.
Sewage treatment systems with sectional type ceramic membrane can also have strong cleaning function, by adding strong acid solution and strong base solution in strong cleaning case, the organic impurity that ceramic membrane internal surface grows because of not using for a long time can be removed, organic impurity is generally liver moss and phycophyta, and conventional purging method is difficult to remove.
Sewage treatment systems with sectional type ceramic membrane can also be provided with automatic vibration filtering net, the sewage be pumped in foul water tank due to suction disc comprises leaf, the bulky refuses such as plastics bag, if do not carry out coarse filtration, be easy to blocking ceramic membrane filter system, therefore automatic vibration filtering net can by the bulky refuse in sewage, medium-sized rubbish and small-sized rubbish classified filtering, thus avoid the blocking of purpose ceramic-film filter, when the rubbish that filtering net adheres to is more, water pump can because suction causes producing negative pressure in pipeline less than enough water, and when the pressure switch in pipeline detects the negative pressure signal of setting, feedback signal starting shock pump, rubbish on filtering net will be attached to shake off, make the filtration condition that filtering net remains good.
