In-suit aeration device suitable for black and stinking water body

Abstract

The invention belongs to the field of river pollution treatment, and especially relates to an in-suit aeration device suitable for black and stinking water body. The in-suit aeration device suitable for black and stinking water body comprises a motor which is vertically arranged on the water surface, a gas source device, an automatic control system, an aeration diffusion chamber, and an aeration device; the aeration diffusion chamber is arranged in water right below the motor; the bottom of the aeration diffusion chamber is provided with an opening; a plurality of aeration diffusion holes arearranged in circular arrays at equal intervals on the side wall of the chamber body; a rotating shaft and a gas guide pipe are arranged to be vertical, and are designed to pass through the center of the aeration diffusion chamber and are connected with the aeration device at the lower end of the aeration diffusion chamber; the aeration device comprises gravity aeration heads, and telescopic gas guide pipes; the telescopic gas guide pipes are arranged on the rotating shaft and the lower end side wall of the gas guide pipe in circular arrays at equal intervals; the telescopic gas guide pipes arearranged to be horizontal; each telescopic gas guide pipe is provided with a gravity aeration head. The in-suit aeration device is capable of adjusting aeration semidiameter based on reoxygenation effects, and realizing aeration with different aeration influence semidiameters.

Description

technical field [0001] The invention relates to the field of river pollution control, in particular to an in-situ aeration device suitable for black and odorous water bodies. Background technique [0002] With the rapid development of industrialization and urbanization, a large amount of waste water is directly discharged into the river, coupled with the untreated discharge of agricultural and rural waste water, the amount of pollutants incorporated into the river exceeds the purification capacity of the water body itself, and the river course presents a black and smelly phenomenon. It continues to deteriorate and seriously affects people's production and life. The black and odorous water body is mainly due to the high content of pollutants in the water body. During the degradation process, a large amount of dissolved oxygen is consumed, resulting in a concentration of less than 2mg / L for dissolution. The water body is transformed into an anoxic or anaerobic state. The anae...

AI Technical Summary

Problems solved by technology

A too small influence radius will increase the oxygen-enrichment efficiency of the river, and some equipment at this stage use high energy consumption to enhance the influence radius

Therefore, there are problems such as unstable aeration effect, high energy consumption, and incomplete governance.
