Description
Technical field
The utility model relates to gas-liquids to be crushed refinement technology field more particularly to a kind of high efficient gas and liquid mixing arrangement.
Background technique
Natural water body has certain self-purification capacity, and wherein the oxygenolysis of microorganism is the main path of the self-purification of water.
If dissolved oxygen content is lower in water body, aerobic microbiological will be suppressed, and anaerobe is in active state.Work as entrance
When the total amount of pollutant is more than water body self-purification ability in water body, dissolved oxygen can be depleted by aerobic microbiological in water body, leads to water
Anaerobic state is presented in body, and contaminant remaining is broken down into ammonia, methane, carbon dioxide, vulcanization under the action of anaerobe
Ammonia etc. has the gas of toxic to aquatile.Meanwhile hydrone be combined into the metabolite of various microorganisms it is biggish
Pollutant of the polymerizable molecular group further by way of absorption and in water body is combined closely, and the self-purification capacity of water body is finally caused
The generation for phenomena such as losing, and fouling along with water body nigrescence, brings strong influence to ambient enviroment.It is how efficient to water body
Oxygenation is to repair the key point of water body.
During the aerobic treatment of stain disease, aeration is an important link in processing system, it is therefore an objective to be
The content of dissolved oxygen in reaction tank is kept, dissolved oxygen needed for guaranteeing aerobic microbiological decomposing pollutant, and make in reaction tank
Microorganism, pollutant, dissolved oxygen are sufficiently fused and are contacted, and provide optimum condition for microbial degradation pollutant.Traditional
Dissolved oxygen mode mostly uses greatly blast aeration, and blast aeration mostly uses greatly the porous diffusion tip of submerged or air nozzle to generate gas

This, improves dissolved oxygen efficiency and oxygen utilization rate is the important measures for reducing sewage treatment plant's operation energy consumption.
To its biodegradability, (also referred to as biology can drop reciprocation in water body between pollutant and environmental matrices and pollutant
Xie Xing, that is, the complexity being degraded by microorganisms) have a significant impact.Solubilised state or particulate form are naturally organic in organic matter and environment
Matter combines, and causes it freely to dissolve form and largely reduces, and the interaction in water body between pollutant, which is allowed to combine, forms big point
The contact area of subset group or the very strong molecule of polarity, pollutant and microorganism greatly reduces, it is difficult into the cell of organism
Film is absorbed by Institute of Micro-biology, is reduced so as to cause the biodegradability of pollutant.Even if improving the dissolved oxygen concentration in water body at this time,
The removal effect of pollutant is also extremely difficult to require.Therefore while realizing water body compared with high-solubility oxygen concentration, how to water
Pollutant carries out cutting refinement in body, has the function of to raising pollutant Biochemical Treatment very positive.
