Dredging engineering refers to the use of dredgers or other implements and artificial underwater excavation for the purpose of widening and deepening the water and soil works. The dredging design of dredging project should try to change the internal structure of the water flow by changing the geometric boundary of the river flow, so that the newly formed flow structure can not only ensure that the sediment no longer silt up in the channel (at least before the next flood season), and can transport the sediment into the deep trough. To maintain the stability of the channel.
River Aeration Technology
The river aeration technology is based on the characteristics of the anoxia after the river is polluted, which is filled with air (or oxygen) artificially and accelerates the process of water reoxygenation, in order to improve the level of dissolved oxygen in water, restore and enhance the vitality of aerobic microorganisms in the water body, so as to purify the pollutants in the water and improve the water quality of the river. Aeration aeration technology combines the principle of aeration oxidation pond and oxidation channel, combining the characteristics of six and complete mixing, which is beneficial to oxygen transfer and liquid mixing. It is an effective sewage treatment method.
Bioremediation of contaminated soil refers to reducing the concentration of toxic and harmful substances in the environment or making it completely harmless by using biological metabolism activities under certain conditions, so that the contaminated soil environment can be partially or completely restored to the original state. In terms of soil pollution treatment, the biggest disadvantage of traditional physical and chemical remediation technology is that the removal of pollutants is not thorough. It leads to the occurrence of two pollution, which brings about a certain degree of environmental health risk. Bioremediation has the advantage of physical repair and chemical remediation: the cost of processing is low. The treatment effect is good. It has low impact on the environment. It will not cause two pollution. It is easy to operate and can be disposed locally.
