Problems solved by technology

The exogenous pollution of the lake is reduced and the water quality is improved, but the pollutants in the sediment will also be released to a certain extent, and the nutrients in the polluted sediment will be re-released into the water body, resulting in water pollution

Abstract

The invention discloses an integrated treatment system and method for lake water environment treatment. The system comprises a sludge suction net and aeration devices, wherein the sludge suction net is connected with sludge discharge pipes through sludge lifting pipes, sludge pumping pumps are arranged on the mud discharging pipes, and controllers are connected to the sludge pumping pumps; the sludge suction net comprises main mud conveying pipes and auxiliary mud conveying pipes, wherein the main sludge conveying pipes are horizontally distributed at equal intervals, and the auxiliary sludgeconveying pipe is arranged between each two parallel main sludge conveying pipes in a crossed mode; and the aeration devices are connected with the sludge suction net through chain ropes. The construction method comprises the steps of measurement lofting, lake bottom sludge removal, sludge suction net arrangement, aeration device installation and system test operation. According to the integratedtreatment system, sludge at the bottom of a lake can be cleaned periodically, deposition of the lake sludge can be reduced, so that nutrient substances in the bottom sludge are reduced to be releasedinto a water body, and maintenance cost is low; and the construction method is simple in steps, the treatment requirements of the lake bottom sludge of different sizes can be met, the good water quality of the water body can be kept for a long time, and meanwhile, the oxygen content in the water body is increased.

Description

technical field [0001] The invention relates to an integrated treatment system and method for lake water environment treatment. Background technique [0002] Due to the existence of endogenous pollution loads in heavily polluted lakes, even when the discharge of pollution sources from outside the lake, such as industrial and agricultural wastewater and domestic sewage, is effectively controlled, the pollution of the lake water is still not significantly controlled. The main reason is Pollution from endogenous loads. [0003] The release of TN from the lake sediment accounts for 18.5% of the total pollution, and TP accounts for 29.4% of the total pollution. Even if the external pollution into the lake is completely controlled, only the release of the lake sediment and the resuspension and dissolution under the action of power will also cause algal blooms. rapid reproduction. The exogenous pollution of the lake is reduced and the water quality is improved, but the pollutants...
