Problems solved by technology

The existing biological turntable technology is currently mainly used in the treatment of urban sewage and industrial wastewater, but it also has the following disadvantages: 1. The disk is flat, and it is difficult for general microorganisms (such as indigenous microorganisms) to attach and reproduce on it. special microbial strains
If it is used in the water purification of rivers and lakes, the addition of microorganisms may cause the imbalance of the original biological population, resulting in ecological risks; 2. The disc has a two-dimensional structure, and the contact surface area between the disc and water is small, so the treatment efficiency is low; 3. The disc plane is parallel to the water flow direction, so the water flow energy cannot be effectively used to drive the turntable to rotate, and power consumption is required

Embodiment Construction

[0021] figure 1 , three turntables are coaxially assembled together. Such as figure 1 , 2 As shown, the turntable for photocatalytic and biological treatment of water includes a rotating shaft 1 connected to the blade 2 and the baffles 3 on both sides of the blade through a flat key, the inner surface of the blade 2 is planted with bionic aquatic plants 4, and the outer surface of the blade 2 is coated with titanium dioxide 5 The shape of the blade 2 is designed to be streamlined according to the principle of hydrodynamics, so that the impeller can rotate under the action of water flow energy. Titanium dioxide 5 is plated on the inner side of the baffles on both sides of the blade, and the outer side is corrugated, and bionic aquatic plants 4 are planted on it.

[0022] Will figure 1 The turntable for photocatalytic and biological treatment of water is installed on the sewage treatment device, and the treatment device is parked in the water area of ​​the river (lake) to be...

Abstract

A rotational disk mechanism for treating water by photocatalytic and biological method is composed of rotary shaft and blade wheel fixed to said rotary shaft. Said blade wheel consists of blades and barrier plates at both side of blades. The bionic waterweed is planted on external surface of barrier plate. The internal surfaces of barrier plates and blades are plated by TiO2. It features the integration of biochemical, aerating, photocatalytic and adsorptive techniques for higher treating effect.

Description

technical field [0001] The invention relates to a water treatment device and method, more particularly to a bionic aquatic plant turntable used in a water pollution device and a water treatment method thereof. Background technique [0002] Biological turntable sewage treatment technology was founded in Stuttgart Institute of Technology, Germany (Li Shizhang. Biological turntable sewage treatment—analysis of sewage treatment project of Shenyang fur factory. Journal of Shenyang Institute of Architecture and Engineering, 1994, 10(1): 40-44). The biological turntable is a kind of biofilm wastewater treatment equipment. A conventional biological turntable is composed of many small-spaced discs or polygonal discs fixed on a shaft. The disc is made of polyvinyl chloride, polyethylene, foam polystyrene, glass steel, aluminum alloy and other materials. Discs are flat, spot corrugated or combined. The turntable rotates under the drive of the motor (edited by...
