Abstract
The invention discloses an ecological desilting method and a desilting device thereof. An ultrasonic depth finder is used for measuring the lake bottom depth, the depth of a sucking head buried in the silt is regulated according to the measured lake bottom depth, a high-pressure water pump is started for absorbing lake bottom water, and feeds the water into the sucking head so that the sucking head begins to work, the silt sucked by the sucking head is conveyed to a silt cabin arranged on a desilting operation ship, and finally, the silt in the silt cabin is conveyed to a silt filter press for filter pressing. The invention belongs to the ecological desilting method with the advantages of thorough desilting effect, no damage to the ecological environment of the lake and no secondary pollution generation on a water body. The invention simultaneously creates conditions for the subsequent biologic technology intervening when clearing contaminated sediment to the furthest degree.
Description
Technical field
The present invention relates to a kind of removing lake silt, administer the method for lake water pollution, and for implementing the Accrete clearing device that this method designs.

Its further technical scheme is: the rear portion of described suction nozzle 2 is equipped with underwater camera device 8.
Useful technique effect of the present invention is:
The present invention implements ecological dredging to Taihu Lake and other shallow lakes, is final purpose with the restoration of the ecosystem in lake, when removing pollutants in sediments to greatest extent, for the intervention of follow-up biotechnology creates conditions.On the basis of ecological dredging, by integration engineering and non-engineering measures such as engineering measure, environmental improvement, ecological engineering and management, repair the ecosystem, ensure lake, river self-purification capacity, ecology recovering health and sustainable development, characteristics are as follows:
(1) suction nozzle of the present invention's employing utilizes hydromechanical Coanda effect, can prevent effectively that the mud diffusion from causing the secondary pollution to water body, reaches the ecological dredging purpose.
(2) the high-pressure spray hydromining in the suction nozzle wherein contains a large amount of nitrogen phosphorus and poisonous and harmful substance with the eutrophy water layer on the mud, after draining by suction nozzle the eutrophic state of water body is improved.
(3) can better control the desilting precision by sounding gear and underwater camera device, under the prerequisite that does not injure the riverbed, carry out operation.
(4) mud that salvages is subtracted the appearance mummification, reduce to stack the space, be convenient to transportation, and can be used as the raw material use of organic fertilizer or constructional materials.
(5) binary dredging operation ship shallow draft of the present invention, can arrive lakeside or the river course that silts up in operation; Simultaneously, bigger floor space is convenient to the installation control of equipment and is regulated.
