High dissolved oxygen generating device and application thereof

Abstract

The invention relates to a high dissolved oxygen generation device. The high dissolved oxygen generation device comprises an oxygen tank and an air inlet pipe, and is characterized in that one end of a variable-frequency high-pressure pump or a diaphragm pump is connected with one end of a low-pressure dissolved oxygen inlet pipe, the other end of the variable-frequency high-pressure pump or the diaphragm pump is connected with a high-pressure dissolved oxygen outlet pipe extending into a pressure tank, and a flat spray nozzle is mounted at the tail end of the high-pressure dissolved oxygen outlet pipe in the pressure tank; and an ultra-micro bubble dissolved oxygen outlet pipe is arranged at the bottom of the pressure tank, one end of the ultra-micro bubble dissolved oxygen outlet pipe extends into the bottom of the pressure tank, a valve is arranged at the tail end of the other end of the ultra-micro bubble dissolved oxygen outlet pipe, and the other end of the ultra-micro bubble dissolved oxygen outlet pipe is further connected with other devices or parts. The high dissolved oxygen generating device disclosed by the invention can not only solve the problem of low oxygen dissolution efficiency of a traditional oxygen-increasing way, but also prevent oxygen from escaping due to oversaturation and improve sewage treatment efficiency; and furthermore, the endogenous respiration effect of microbes can be improved, so that the high dissolved oxygen generation device can reduce the generation of residual active sludge during sewage treatment and degrade bottom sludge in ponds, lakes and reservoirs, and further has extensive social effects and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of oxygenation, and in particular relates to a high-dissolved oxygen generating device and its application. Background technique [0002] In aquaculture, sewage treatment, purification treatment of ponds or rivers and lakes, sludge degradation and other treatment processes that require oxygen, the dissolved oxygen status in water is an important factor affecting the effect. In aquaculture, the food intake of farmed fish and shrimp, the digestion and absorption rate of the feed after ingestion, as well as the growth rate and the bait coefficient are closely related to the dissolved oxygen in the water. Under the condition of low dissolved oxygen or anoxic, the material circulation in the water is destroyed. If the toxic substances cannot be transformed in time, it will not only reduce the aquaculture output of the water body, but also cause the death of a large number of aquatic animals. In modern sewage t...
