Embodiment Construction

[0023] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing: Figure 1~7 As shown, a plug-flow type water wheel drives a biological turntable, including a reaction tank 1, a water baffle 2 connected to the tank body, and a water outlet box 8 located below the tank body; Divided into drive area 3 and biological turntable area 4; the bottom of drive area 3 is slightly higher than the bottom of biological turntable area 4, so that the biological turntable areas 4 on both sides are connected, and the entire biological turntable area 4 is approximately a U-shaped groove. A water wheel 31 driving device is installed in the drive area 3, and the vertical baffle 42 divides the biological turntable area 4 into a plurality of compartments 9, and a biological disc 41 is installed in each compartment 9; A number of baffles 42 parallel to the direction of the biological disk 41 are arranged; the biological rotating disk area...

Abstract

The invention discloses a push-flow type waterwheel-driven biological turntable, which includes a reaction tank, a water retaining plate connected to the tank body, and a mud discharge bucket; the reaction tank includes a drive area located in the middle of the tank body and a The biological turntable area communicated with each other; a water wheel is provided in the driving area; a biological disc and a baffle are arranged in the biological turntable area, and the biological disc and the water wheel are connected through the same rotating shaft. The baffles are placed up and down from left to right; a water outlet weir and a water distribution plate are arranged on the wall at one end of the biological turntable area; a mud discharge hopper and a mud discharge pipe are arranged at the bottom of the reaction tank; The addition of baffles in the middle optimizes the hydraulic flow state of the water in the contact reaction tank, effectively prevents the short flow phenomenon in the reaction tank, averages the actual hydraulic retention time in the reaction tank, and improves the contact efficiency between the sewage and the biological turntable, thus enhancing the aerobic environment. Nitrification performance of the biorotor.

Description

technical field [0001] The invention belongs to the technical field of water pollution control, in particular to a push-flow type water wheel-driven biological turntable. Background technique [0002] The existing centralized urban sewage treatment process is relatively mature, but it needs to be equipped with a complete sewage collection pipe network, and the treatment scale is large, and the construction and operation costs are high. It is of great practical value to develop treatment processes and facilities with low energy consumption, small investment, simple operation and management, and strong adaptability to solve the scattered domestic sewage in villages. [0003] Biological turntable technology is a kind of biofilm method, which has the characteristics of large microbial mass, strong impact load resistance, and no need for aeration. Microorganisms adhere to the disk and gradually form a layer of biofilm. Between the air and the sewage, oxygen is obtained from the ...
