Abstract

The invention discloses an adding equipment of a post-ozone air ejector. The adding equipment comprises an ozone generator, an ozone distribution pipeline and an ozone contact pool, wherein an aerating disc is installed at the bottom of the ozone contact pool, and the ozone gas enters into the aerating disc through the distribution pipeline; a bypass pipeline consisting of the air ejector is additionally arranged on the distribution pipeline, and one-off valves are respectively arranged on the distribution pipeline and the bypass pipeline; besides an ozone gas inlet, the air ejector further comprises a mixed gas inlet connected with an air blower; the mixed wind outlet of the air ejector is connected with the aerating disc through the distribution pipeline. The adding equipment disclosed by the invention can be used for solving the technical problem that a post-ozone adding system of a water plant has different demands on the ozone adding rate in different seasons and the operating cost is effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of municipal water supply treatment. Background technique [0002] Ozone activated carbon technology plays an important role in removing micro-polluting organic matter, reducing disinfection by-products and improving sensory indicators such as smell and taste in the water purification process. With the deterioration of raw water quality and the gradual improvement of effluent standards, ozone activated carbon technology has broad application prospects in China. The ozone system mainly includes three parts: gas source, ozone generation and ozone dosing. The specifications of the ozone generator are generally determined according to the maximum dosage rate and the high daily water supply. There are two types of ozone dosing: pre-ozone dosing and post-ozone dosing. The post-ozone dosing system includes an ozone gas distribution pipeline and an ozone contact pool. The effective water depth of the rear ozone ...
