Background
River pollution control is a difficult problem puzzling local governments at all levels, and industry specialists try different pollution control modes to treat sewage, but the effect is very poor. In recent years, a new pollution control mode is adopted, and bacteria control is realized. Bacteria such as nitrifying bacteria are cultivated in a river water body, organic matters in the water body are decomposed by the bacteria such as nitrifying bacteria, the oxygen content of the water body is required to be sufficient for cultivating nitrifying bacteria, in order to improve the oxygen content of the water body, technicians can inject oxygen into the water body, oxygen bubbles can be absorbed by water in the process of floating up in the water body, so that the oxygenation effect is achieved, in general, the oxygen is discharged into the water body through small holes, micro bubbles smaller than 2mm can be generated, the mutual contact area of gas (oxygen), water and solid (active sludge microorganisms) is enlarged, the gas, liquid and solid mass transfer efficiency is high, but in the practical situation, because most of river depths are shallow, the rising path of the oxygen bubbles is too short after entering the water body, the water body is not enough to absorb the air bubbles, the bubbles are already rising to the water surface, the test results show that the oxygen is introduced in the depth of 1M, the oxygen utilization rate is only 16%, and the oxygen utilization rate can reach 80% in the depth of 5M, so that the depth of water is deeper, and the oxygen utilization rate is higher. In order to enable the water body to absorb enough oxygen and enable the oxygen content to be enough, technicians can increase the depth of the water body and prolong the ascending path of oxygen bubbles by digging a deep river bed, but the mode is large in engineering and high in cost. The supply of pure oxygen is increased by technicians, so that the water body absorbs enough oxygen, but the consumption of oxygen is huge, the waste is serious, and the pollution control cost is increased.
