Detailed Description
The technical solution of the present invention is further described below, but the scope of the claimed invention is not limited to the described.
As shown in figure 1 and figure 2, a system for promoting river course quality of water, including river course 1, aeration mechanism, sedimentation tank 6 and blowdown subassembly 7, aeration mechanism installs in river course 1 to span river course 1, sedimentation tank 6 is established in the bottom of river course 1, and sedimentation tank 6 spans river course 1 to be located aeration mechanism's upstream side, blowdown subassembly 7 is arranged in discharging the silt in sedimentation tank 6 outside river course 1. When the sedimentation tank is used, the sedimentation tank 6 is lined with concrete, and the slope position of the sedimentation tank 6 does not influence the stability of the support column 3.
Aeration mechanism includes many support columns 3 and air pump, and many support columns 3 are installed side by side in the bottom of river course 1, and many support columns 3 link together through MBR membrane 2, and the gas outlet of air pump passes through the trachea and is connected with MBR membrane 2. Air is pumped to the MBR membrane 2 by an air pump to perform aeration.
The MBR membrane 2 is arranged in a vertical direction. Compare with the mounting means with MBR membrane 2 tiling on river course 1 bottom surface, with MBR membrane 2 vertical arrangement, because it does not contact with river course 1 bottom surface, so MBR membrane 2 is bigger with the area of contact of water, has alleviateed the disturbance of air current to river bed suspended matter in the aeration process simultaneously.
The supporting columns 3 are also connected together by a cross beam 5. In use, it is determined whether the addition of cross beams 5 is required according to the lateral spacing of the support columns 3.
