(5) embodiment:

Embodiment one:

Referring to Fig. 1, the utility model comprises treating pond 19 and medicine storing pot 1, its gordian technique is that filter cylinder 18 is installed in treating pond 19, filter cylinder 18 is made of the compound screen membrane 17 of stainless steel, filter cylinder (18) is made of round end and inboardend, round end is connected by rotating disk (13) with inboardend, the other end of round end is installed break-in wheel disc 20, the opposing party's opening of inboardend, one side of opening is installed on the inwall for the treatment of pond 19 1 ends, forms passage between the inwall of all the other tripartite outer walls of filter cylinder and treating pond 19.Be provided with chemicals feeder 16 in the inboardend of filter cylinder 18, be provided with cover tube 14 above chemicals feeder 16 imports, medicine storing pot 1 links to each other by chemical feed pipe 7 with chemicals feeder 16.The entrance end of chemicals feeder 16 connects chemical feed pipe 7, and exit end is a clear water output 15, valve tube 6 is installed on chemical feed pipe 7 is inserted in the inboardend of filter cylinder 18, and valve tube 6 is concordant with the bottom of cover tube 14 in filter cylinder 18.End at treating pond 19 is vertically installed automatic sludge discharge pipe 21, and the height of scum pipe is higher than the height of chemicals feeder 16, and the import of scum pipe is lower than the import of chemicals feeder, and the diameter of scum pipe is greater than the diameter of clear water output 15.The ingress fixed installation cover plate 10 for the treatment of pond 19, have wash-out hole 9 and air inlet port 11 on the cover plate 10, chemical feed pipe 7 and valve tube 6 are provided with sump pump interface 12 through cover plate 10 in the ingress, wash-out hole 9 is used to insert wash tube and running water pipe, is convenient to cleaning pond 19; On the pool wall of the same end of automatic sludge discharge pipe 21, be provided with artificial scum pipe 22 and venting hole 23.Be provided with upflow tube 5 and blow-off pipe 8 on the tank skin of medicine storing pot 1 one ends, link to each other with blow-off pipe 8, when upflow tube 5 is convenient to water treatment agent above rated liquid level, overflow from here, blow-off pipe 8 is convenient to the cleaning of medicine storing pot 1; Be provided with water sprayer 4, pore 3 and liquid level instrument 2 on the tank skin of the medicine storing pot the other end, water sprayer 4 is used to prepare water treatment agent, and pore 3 is consistent air pressure and the normal atmosphere in the container, liquid level instrument 2 be convenient to observe water treatment agent height, what.Here treating pond 19, filter cylinder 18 and medicine storing pot 1 be shaped as cylindrical.

Embodiment two:

Other structure of present embodiment is identical with embodiment one structure, and different is that filter cylinder 18 is closed filter cylinder, forms passage between the inwall of the outer wall of filter cylinder and treating pond 19.

The shape for the treatment of pond 19, filter cylinder 18 and medicine storing pot 1 also can be square.

Principle of work of the present utility model is as follows:

Treating pond 19, filter cylinder 18, medicine storing pot 1 all are containers of sealing, and medicine storing pot 1 main storage water treatment agent is standby, air inlet port 11 external high pressure positive blowers.Sewage from sump pump interface 12 by the water pump suction, after at first intersecting (aeration) with the high-pressure air that enters from air inlet port 11, air is discharged from venting hole 23, sewage is blown into treating pond 19, sewage slowly goes up from the treating pond bottom, enter in the filter cylinder 18 by compound screen membrane 17 diafiltrations of stainless steel, the zone in the filter cylinder 18 is a clear water zone, and the passage area that forms between cartridge exine and the treating pond inwall is the contraminated zone.Chemicals feeder 16 is " L " type and uprightly is installed on the inwall of filter cylinder 18, leave passage between the inwall of chemicals feeder import and cover tube, treat that the clear water in the clear water zone rises when covering the tube overhead height above the chemicals feeder import, clear water enters chemicals feeder 16 along the inwall of cover tube 14, force current to change direction twice, make water generates eddy current and negative pressure, make chemical feed pipe 7 and clear water output 15 produce siphonage simultaneously, produce negative pressure in the chemicals feeder, utilize pressure difference, medicament in the medicine storing pot 1 is sucked chemicals feeder through chemical feed pipe 7, chemicals feeder work, medicament and water are at the inner thorough mixing of chemicals feeder, water is through sterilization, purifying the back discharges from clear water output 15, thereby finish the process of draining simultaneously and dosing, when clear water was discharged, the round end that break-in wheel disc 20 drives filter cylinder 18 slowly rotated.Whole process is finished from pneumatic aeration, Automatic Dosing, automatic filtration work, thereby finishes the self-purging work to water.

When stopping to extract sewage, when the clear water in the filter cylinder 18 is reduced to cover tube bottom height, clear water output 15 anhydrous rows, air admission valve tube 6 and chemical feed pipe 7, medicament can not be sucked out, and chemicals feeder quits work.This process is finished and is stopped dosing work automatically.

When the suspended substance in the sewage sticks to when screen membrane is stopped up, the contraminated zone sewage level goes up, when sewage floods whole scum pipe 21, sewage and filter residue are discharged from automatic sludge discharge pipe 21, produce negative pressure in the scum pipe 21, raw sewerage is also together discharged, because the import of scum pipe 21 is lower than the import of chemicals feeder 16, be discharged from sewage, in the process that descends, clear water in the clear water zone is by 21 sucking-offs of automatic sludge discharge pipe, because water (flow) direction changes, break-in wheel disc 20 drives the round end opposite spin of filter cylinder 18, at this moment adherent mud on the screen membrane, suspended substance, particles etc. are washed away totally repeatedly by clear water.Thereby finish the automatic cleaning and the work for the treatment of pond automatic sludge discharge of screen membrane.Can enable artificial scum pipe 22 in case of necessity.
