at present, the market technology and the existing defects and shortages are mainly as follows:

firstly, the engineering quantity of revetment and dredging is large, the cost is high, and secondary pollution is easily caused by improper treatment of the cleaned sludge;

secondly, the complete interception of the pollution cannot be realized, and because rivers and lakes are open systems, pollution sources like atmospheric sedimentation cannot be completely intercepted;

thirdly, the treatment of symptoms and root causes are not permanent, the water quality of the changed water after dredging can not be maintained, and as the micro-ecosystem of the surface water is damaged along with the removal of the bottom mud, the self-purification capacity of the river and the lake is reduced, and the water body will be deteriorated again once meeting exogenous pollution;

and fourthly, a plurality of earth surface water areas belong to closed semi-closed water areas, such as lakes, reservoirs, harbors, large lake branches, dead river branches, urban dead water riverways and the like, and the water bodies are closed, slowly flow and unsmooth in exchange with the outside, are in a dead water state, are extremely low in self purification capacity, even if a small amount of pollution sources enter the water bodies, and can not be decomposed and purified in time, so that the water quality can be gradually eutrophicated in daily and monthly accumulation, and then the foul water is caused to form a vicious circle.
