Black and odorous water body treatment system and method

Abstract

The invention provides a black and odorous water body treatment system and a black and odorous water body treatment method applying the system. The black and odorous water body treatment system comprises a water inlet tank, an ozone generator, an oxidation tower, an MABR reactor, a water outlet tank and a tail gas destroying device, wherein a micro-interface generator is also arranged at the bottom of the oxidation tower and is used for crushing gas emitted by the ozone generator into bubbles. According to the invention, the micro-interface generator can smash bubbles into micron-sized bubbles, so that the phase interface area between a gas phase and a liquid phase is increased, and ozone gas can be better dissolved in black and odorous water to form a gas-liquid emulsion for increasing the reaction efficiency; and the ozone gas in the black and odorous water body is crushed into small bubbles, and the volume of the gas is reduced, so that the floating buoyancy of the bubbles is reduced, the retention time of the ozone gas in the black and odorous water body is prolonged, and the reaction efficiency is further improved.

Description

technical field [0001] The present invention generally relates to the field of black and odorous water treatment, and more specifically relates to a treatment system and method for black and odorous water. Background technique [0002] As a kind of advanced oxidation technology, ozone catalytic oxidation technology decomposes under the action of catalyst and synergistic oxidant to produce hydroxyl radicals, which non-selectively degrade the refractory pollutants in wastewater, so as to reduce the COD value of wastewater and improve The purpose of the biodegradability of wastewater, and at the same time no secondary pollution, has been widely promoted in the field of advanced treatment of industrial wastewater. [0003] Most of the existing ozone catalytic oxidation devices use the pump body to directly pump the ozone gas into the reactor. The residence time of the ozone gas in the reactor is short, and most of the ozone gas floats out of the reactor before fully reacting, wh...

Problems solved by technology

[0003] Most of the existing ozone catalytic oxidation devices use the pump body to directly pump the ozone gas into the reactor. The residence time of the ozone gas in the reactor is short, and most of the ozone gas floats out of the reactor before fully reacting, which not only reduces the reaction efficiency Also increased treatment cost, therefore, need a kind of treatment system and method thereof of black and odorous water body, to at least partly solve the above-mentioned problems
