Abstract

Cage-like biological contact cleaner device comprises a multiangular cage (1) provided with number of intersections (4) disposed between the horizontal joint edges of the cage surfaces (7) said intersections (4) including three horizontal rows of circular orifices (5). Along the planes perpendicular to the axis of the cage rotation the tube sections (6) are disposed which have a form of open loops the arrangement thereof being such that the bend top of each loop passes through an orifice (5) made in particular intersection (4) and is placed closely to the cage surface periphery. One end of each tube section (6) is inserted into an orifice (5) placed approximatively in the mid point of each intersection height while the second end of the same tube section (6) is inserted into still another orifice (5) made in the adjacent other intersection (4) this orifice being placed nearest to the axis of cage rotation whereby both ends of each tube section (6) are set up with their openings in direction of the cage rotation. The space between said tube section (6) is filled with a loose material (8) comprising pieces of cut tubes, ceramical rings or polystyrene pellets, respectively.

Description

CAGE-LIKE BIOLOGICAL CONTACT CLEANER DEVICE FOR WASTE WATER TREATMENT
The present invention relates to biological contact cleaner device designed for treatment of waste water.
Description of the Prior Art
It is a primary task in the development of the biological contact cleaner designed for waste water purification to attain an increased air volume delivered into the waste water which means to achieve an enlargement of the particular active surfaces of said biological contact members serving to sedimentation of bacteria stimulating the process of water aeration.
Said task has been pursued, for instance, in relation to de sign of the biological contact disc members formed from a number of perforated tubes wound in a spiral as it is disclosed in CS Pat. No.257 847, EP No. 198451, EP No. 247 5 and DE Pat. No. 2 919221, these devices being adoptable for joing with a shaft cover as it is disclosed, for example in CS Pat. No. 270 100 and analogical EP No. 339 907. These disclosuresrefer to the biological contact cleaner devices the surfaces thereof being enlarged by inside and outside wall surfaces of the tube sections of relatively greater diametr into which still another tubes of lessen diametr may be inserted.
Summry of the Invention
The cage-like biological contact cleaner device according to the invention presents a substantial improvement in providing maximum of an active contact surface and thus in delivering as much of air into the treated water as possible. Said device cage body is rotatebly mounted about the horizontal axis in the inside of the waste water tank the multiangular cage being provided with a number of intersection disposed between the horizontal surface joint edges and the shaft cover, said intersections being provided with three rows of circular orifices and in the planes perpendicular to the axis of cage rotation a number of plastical tube sections may be fabricated, for example, from corrugated electrical conduit and are arranged in a form of open loops the bend top of each of them being passed through a circular orifice made in particular intersection closely to the cage periphery. One end of said open loops is inserted into an orifice made approximatively in mid point of each intersection while the second end of the same tube loop is inserted into another circular orifice made in the nearest next intersection and closely to the axis of the cage rotation, whereby the both ends o:f each tube section are let open in the direction of the cage rotation. The remaining space between the tube sections is filled with plastic tube cuttings, ceramical rings or polystyrene pellets.
The efficiency of the described biological contact cleaner device providing an unusually enlarged functional surface and therewith an increased capacity of air. delivery into the purified water has been tested by the Institute of Hydrological Research in Prague. In comparision with the result of tests carried out in relation to the biological contact cleaner device according to the prior art CS Pat. No. 271 819 the tests proved that although the waste water volume was reduced to the half the present invention was capable of double oxygen generation as it will be shown by the following average test results.
Average results of the tests:
I ..... prior art according to CS Pat.271 819
II .... device according to present invention

Fig.2 ... a plan view of the same device as above
Description of an exemplary Embodyment
The cage-like biological contact cleaner device comprises an octahedron cage 1 mounted rotatebly within the waste water tank 9 about horizontally disposed shaft 2, said cage 1 being divided by a number of intersections 4 disposed between the horizontal joint edges of the surfaces 7 and the cover 3 of said shaft 2. The tube sections 6 passed through circular orifices 5 made in the body of said intersections 4 as shown on Fig. 2 take in air by their open ends turned in the direction of the cage rotation as indicated by arrow, while emerging from the waste water and thereafter, release the obtained air into same water in form of bubbles when the lowes point of rotation has been overcome.
In addition, a substantial volume of air is delivered into the waste water supply by loose filling 8 of plastic tube cuttins, ceramical rings or polystyrene pellets placed in the space between the single tube sections 6 of the cage 1. The se fillings multiply to considerable extent the active surface of the biological contact cleaner.
