Embodiment Construction

[0015] As shown in the figure, the shell 1, the cone mouth 2, the pressure water inlet pipe 3, the retaining ring 4, the spout or uniform slit 5, and the filler delivery outlets 6 and 7 are regulating devices. figure 2 Middle P is a pressure pump, a pool water outlet 11, a horizontal line suspension 12, an outlet 13 for output packing, a pressure pump water inlet 14, a packing inlet 15, a packing layer 16, and a propeller 17. . The present invention is based on the structure and principle of the annular jet, and uses or other pressure water flow (the pump is commonly used, the suction port of the pump) to inject water from the slit of the annular jet, thereby driving the surrounding water flow to move forward together. When implementing, It can be used alone, or two or more of them can be connected in series with pipelines to achieve the purpose of long-distance transportation of fillers.

[0016] The pipe or cylinder shell of the present invention can be cylindrical or rect...

Abstract

The invention relates to a non-paddle bypass type underwater pushing, transporting and stirring method, which pushes, transports and stirs floating packing by a bypass type underwater propeller. The structure of the bypass type underwater propeller is the structure of a pipeline or the structure of a cylinder. The pipeline or the cylinder is internally provided with a tapered port, the pipe diameter of which is gradually reduced; the pipeline or the cylinder is perpendicularly connected with a pressure water inlet pipe in a communicating way, or is connected with the pressure water inlet pipe in an angle in a communicating way, and the pressure water inlet pipe is communicated to the position of the tapered port with gradually reduced diameter; and water flow of the pressure water inlet pipe flows forward to the tip part of the outside of the tapered port, and drives packing water in the pipeline move forward along the tip part of the tapered port. The non-paddle bypass type underwater pushing, transporting and stirring method provided by the invention is hard to break the packing, the broken packing not only causes the biochemical efficiency reduction of the water body but also the cleaning cost enhancement, and micro-organism is also hard to rush down on the surface of the packing, thus the effects of the pushing, transporting and stirring functions are favorable. Moreover, the non-paddle bypass type underwater pushing, transporting and stirring method enhances efficiency of MBB process, and reduces energy consumption.

Description

technical field [0001] The invention belongs to the technical field of water treatment, and relates to a method and a device for realizing paddleless duct-type underwater pushing and stirring, so as to keep packing in an efficient working state and greatly reduce the loss of packing. Background technique [0002] In the biochemical water treatment process, the MBBR (Moving Bed Biofilm Reactor) moving bed biofilm reactor has the highest process effect and the best quality of treated water. Suspended fillers in MBBR can grow various types of organisms. The principle of MBBR process is to increase the biomass and biological species in the reactor by adding a certain amount of suspended carriers to the reactor, thereby improving the treatment efficiency of the reactor. Since the packing density is close to that of water, it is completely mixed with water during aeration, and the environment for microbial growth is gas, liquid and solid. The collision and shearing action of the ...
