Oxygen enrichment equipment for accelerating restoration of ecological system of black and odorous water body

Abstract

The invention discloses oxygen enrichment equipment for accelerating restoration of an ecological system of a black and odorous water body. The equipment comprises a water inlet air pipeline, a gas-liquid mixing pump, a dissolved air tank, a dissolved air outlet water pipeline and a micro-bubble releaser, wherein the water inlet air pipeline is provided with a water inlet, an air inlet and a wateroutlet air port, the water outlet air port of the water inlet air pipeline is connected to an inlet of the gas-liquid mixing pump, the dissolved air tank is provided with a water inlet air port and adissolved air outlet water port, an inlet air port of the dissolved air tank is connected to an outlet of the gas-liquid mixing pump, an inlet of the dissolved air outlet water pipeline is connectedto the dissolved air outlet water port of the dissolved air tank, and the micro-bubble releaser is arranged at an outlet of the dissolved air water pipeline. The oxygen enrichment equipment has the advantages that micro-bubbles are made by combining a dissolved air precipitation type micro-bubble technology and an air-entraining bubble generating technology, and therefore the problems that the generating process and the operation are troublesome, the requirement for a bubble generator is high, the size of generated bubbles is not uniform, and the cost is high can be solved.

Description

technical field [0001] This article relates to the field of environmental equipment technology, especially an oxygen-enriched equipment that accelerates the recovery of black and odorous water ecosystems. Background technique [0002] With the rapid process of industrialization and urbanization, a large amount of waste water and polluted surface runoff have no time to collect and treat and are directly discharged into rivers. Coupled with the untreated discharge of agricultural waste water, the incorporation of river pollutants exceeds the purification capacity. There is a black and smelly phenomenon. The main treatment methods for black and odorous water bodies include physical methods, chemical methods, biological and ecological methods, and combined methods. River aeration technology, as a low-investment, quick-result river pollution control technology, is preferred in many countries. River aeration technology is based on the characteristics of anoxic rivers after being...
