A black and odorous water treatment device for ecological restoration

Abstract

The invention relates to the technical field of black and odorous water treatment, in particular to a black and odorous water treatment device for ecological restoration, which includes a treatment tank, a water inlet pipe is fixedly connected to the bottom of the side wall of the treatment pool, an air inlet pipe is arranged above the water inlet pipe, and the air inlet pipe runs through the treatment tank. The tank extends into the inside of the treatment tank, the upper side wall of the treatment tank is fixedly connected with the outlet pipe, and the inside of the inlet pipe is fixed with a partition, which divides the inside of the inlet pipe into a heating chamber and a feeding chamber, and the feeding chamber is provided with a A dosing mechanism for adding microbial agents to the inside of the tank, a heating mechanism for introducing hot air into the treatment tank is installed in the heating chamber, and a blocking mechanism for sealing one side of the intake pipe is installed on both sides of the partition end The device first heats the sewage to raise the water temperature to the suitable temperature for the survival of aerobic bacteria, and increases the oxygen content in the sewage through the vibration mechanism, which is beneficial to the survival of the aerobic bacteria.

Description

technical field [0001] The invention relates to the field of black and odorous water body treatment, in particular to a black and odorous water body treatment device for ecological restoration. Background technique [0002] Black and odorous water is an extreme manifestation of organic pollution in water. The mechanism of black and odor in most waters is basically the same. It is caused by the lack of oxygen in the water and the corruption of organic matter. When a large number of organic pollutants enter the water body, under the biochemical action of aerobic microorganisms, a large amount of oxygen in the water body is consumed, and the water body is transformed into an anoxic state, resulting in the proliferation of anaerobic bacteria, and the decay, decomposition and fermentation of organic matter. Black and smelly. [0003] The existing black and odorous water treatment methods are mostly through manual cleaning of water surface garbage, or directly adding aerobic bact...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing black and odorous water treatment methods are to manually clean up the water surface garbage, or directly add aerobic bacteria or oxygen to the black and odorous water body, so as to increase the oxygen content of the water and the number of aerobic microorganisms in the water , to improve the black and odorous water body, but the improvement effect of this method on the black and odorous water body is not obvious

[0004] Especially in winter, due to the low water temperature, after the aerobic bacteria agent is passed into the water, the aerobic microorganisms cannot adapt to the water temperature, the survival rate is low, and the oxygen content in the black and odorous water body is scarce, so the aerobic bacteria agent is directly introduced into the water body, and the water body The number of aerobic microorganisms in the medium increases, and the oxygen consumption further increases, causing a large number of aerobic microorganisms to die due to hypoxia, and oxygen is directly passed into the water body, and it is not easy to combine with water, which is not conducive to the treatment of black and odorous water bodies. In view of this, We propose a black and odorous water treatment device for ecological restoration
