A micro-nano aeration treatment equipment for black and odorous water

Abstract

The invention relates to the technical field of sewage treatment, in particular to black and odorous water body micro-nano aeration treatment equipment. A pressurizing mixing device is used for mixingwater and gas, the mixed water and gas are stored in a gas-liquid mixing pressure tank, a detection system detects the pressure of water entering the pressurizing mixing device and the pressure of gas entering the pressurizing mixing device and detects the internal temperature and water outlet dissolved oxygen amount of the pressurizing mixing device in real time, a control system adjusts the water inlet amount and the gas inlet amount according to detection data of the detection system, a water diversion device is controlled to be started, the water diversion device is used for water diversion before the pressurizing mixing device is started, and a distribution device is connected with a gas-liquid mixing pressure tank, and used for multi-pipeline multipoint distribution and transportation of mixed liquid; a release device releases the mixed liquid transported by the distribution device in a micro-nano bubble mode. Through the action of the black and odorous water body micro-nano aeration treatment equipment, the gas released by a releaser prolongs the oxygen dissolving time in the water body disturbance process, and bubbles are broken to form more uniform tiny bubbles, thereby effectively improving the oxygen dissolving efficiency.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a micro-nano aeration treatment equipment for black and odorous water. Background technique [0002] At present, the main reason for the black and odorous water body is that the self-purification ability of the water body is reduced, organic pollutants are discharged into the water body, and the aerobic decomposition of microorganisms makes the oxygen consumption rate in the water body faster than the reoxygenation rate, and the dissolved oxygen is gradually exhausted, resulting in the water body being hypoxic. In anoxic water, organic pollutants are anaerobically decomposed to produce different types of black and odorous substances, presenting black and odorous water bodies, and black and odorous substances produce strong black and odorous substances, which have a great impact on the environment. [0003] In view of the foregoing, the inventor actively researches and in...
