Problems solved by technology

[0002] The water body enclosure of the bioreactor of the existing water purification device generally adopts a concrete or steel structure pool body, and its structure is relatively complicated, which requires a large cost and construction time
I proposed a solution in the patent application "Water Purification Device and Base Construction System for Suspended Rotary Bioreactor" Application No. 2006101597439. Although the water purification device is very compact and economical, it absorbs oxidation ditch water It deals with the characteristics of low energy consumption operation, but it is only suitable for water purification in large wild natural waters; the submerged hollow fiber membrane bioreactor (hereinafter referred to as MBR membrane bioreactor) is used as an integrated water purification system for domestic sewage treatment The device has the characteristics of small size, high efficiency, stable effluent quality, low bacteria count and other indicators directly meet China's national recycled water standards. However, it is difficult to discharge dead sludge from the bottom of the flat tank of the reaction tank of the MBR membrane bioreactor. If it is used for a long time It cannot be ruled out that dead sludge will seriously affect the quality of produced water
In the north, there is a problem of severe cold in winter, system insulation problem with temperature below 10 degrees Celsius, and equipment antifreeze problem; another key problem is to reduce power consumption, reduce the total cost of the project and improve the level of automation, all need Further improve and enhance

Embodiment 2

[0078] In Fig. 8, 9, 12 and 13, the embodiment 2 after the present invention is shown as a whole;

[0079] The difference between this embodiment and Embodiment 1 is that the six purification elements in the water body S1 of the water purification device are arranged symmetrically on both sides of the water partition wall 37, and a row of purification elements is arranged on each side. The inclined plate settling tank SF for solid-liquid separation is arranged on the periphery of the water body S2, and the inclined plate settling tank SF is close to a rectangle; the inclined tube settler is used in the inclined plate settling tank SF; the inclined tube settler includes a water receiving tank 42 and a water purification tank Sd , sludge flow channel 52, water distribution pipe 50 and inclined pipe 40, the inlet of the water distribution pipe is connected to the water body S2, and the outlet of the water distribution pipe is through holes evenly distributed on the water distribut...

Embodiment 3

[0081] In Fig. 10, 11, 14 and 17, the embodiment 3 after the present invention is shown as a whole;

[0082] The difference between this embodiment and Embodiment 2 is mainly that the water purification device is provided with 12 purification elements, and the purification elements are symmetrically arranged on both sides of the water partition wall 37, and two rows of purification elements 8 are arranged on each side; the water body enclosure of the water purification device System C is to use a water barrier 46 to enclose at least one ditch outside the water body S2 to receive and discharge the water body S3. The water body S3 is a closed ring-shaped water body formed around the water body S2 respectively. Inlet; Raw water channel is set from water barrier 38 between water body S3 and water body S2 and becomes series system (open valve 6, 7 and 14, close valve 8, 10 and 13, or open valve 8, 10 and 13, close valve 6, 7 and 14), adopt continuous operation; or set the raw water...

Embodiment 4

[0088] In Fig. 15 and 16, the embodiment 4 after the present invention is shown as a whole;

[0089] The difference between this embodiment and Embodiment 3 is mainly that an annular suspended water partition wall 58 is set in the water bodies S2 and S3, and the upper part of the suspended water partition wall 58 protrudes from the water surface and is suspended on the horizontal platform 57b and the vertical platform 57a of the rigid frame. Above, the bottom of the suspended water partition wall 58 is in sliding contact with the foundation; the inner and outer sides of the ring-shaped suspended water partition wall 58 form two closed annular grooves; a mast 60 is set in the middle of the intersection of the horizontal platform 57b and the longitudinal platform 57a, and the mast 60 and the suspension Between the suspension point that water-blocking wall 58 top stretches out the water surface, connect cable part, and link cable part can be steel wire rope 59b. In this embodimen...
