Problems solved by technology

[0003] However, in the case of existing air diffusion devices such as microporous aeration devices, the small air bubbles produced by the microporous aeration devices are mostly distributed around the aeration device, and the bubbles interfere with each other. Fusion occurs, thereby reducing the specific surface area and affecting gas-liquid mass transfer

Abstract

The invention discloses a conical water injection nozzle for an activated sludge process, which comprises a conveying pipe, a mounting disc and a plurality of conical nozzles uniformly distributed onthe mounting disc. The mounting disc is mounted at one end of the conveying pipe. The conical water injection nozzle is arranged in an aeration tank that adopts an activated sludge method. The liquidoutlet direction of the conical nozzle is the horizontal direction. The conical nozzle is horizontally arranged in the aeration tank and is used for injecting liquid with a horizontal direction speedinto the aeration tank, so that the surface updating of the liquid is accelerated, the distribution range of bubbles in water in the aeration tank is larger, the distribution is more uniform, and thegas-liquid mass transfer pushing force is enhanced.

Description

technical field [0001] The invention relates to the field of activated sludge method, in particular to a conical water injection nozzle. Background technique [0002] The activated sludge method is an aerobic biological treatment method for sewage, which can remove dissolved and colloidal biodegradable organic matter, suspended solids and other substances that can be adsorbed by activated sludge from sewage, and can also remove some Phosphorus and nitrogen are collective terms for various methods of wastewater biological treatment of microorganisms suspended in water. An important part of the activated sludge method is the aeration tank. The aeration tank is the main body of the reaction. The sewage and the returned activated sludge enter the aeration tank together to form a mixed liquid. The compressed air sent from the air compressor station passes through the laying The air diffusion device at the bottom of the aeration tank enters the sewage in the form of fine air bubb...
