The invention discloses a river channel comprehensive treatment method and relates to the technical field of river channel ecological treatment. The river channel comprehensive treatment method comprises the following steps of intercepting
water flow, specifically, manufacturing
cut-off dykes at the two ends of a river channel to conduct interception on the river channel;
water pumping, specifically, pumping off
river water in a river channel cleanout section; dredging, specifically, conducting comprehensive flushing on the river bottom through a water
torch to enable water to be mixed with
sludge to form mud-water mixed liquid and pumping the mud-water mixed liquid into a buffer
pool; separation, specifically, separating the mud-water mixed liquid in the buffer
pool into flowing water, sundries, gravel particles and
sludge through a multi-stage
filter system; treatment, specifically, firing part of the gravel particles and the
sludge into dyke protection bricks; flow-through, specifically, dismantling the
cut-off dykes. The sludge flushing and cleaning speed of high-pressure water is high, cleaning is comprehensive, and time and labor are saved. Meanwhile,
water resources of non-dredging sections are utilized, and the water impounding pressure of the upstream of the river channel is also reduced. The gravel particles and the sludge are manufactured into the dyke protection bricks to protect two sides of the river channel and facilitate ecological remediation. The treatment method has the advantages of being high in efficiency, environment-friendly, capable of saving resources and beneficial to continuous remediation of the river
ecology.
