The invention relates to a method for purifying river water. By constructing a slow-release structure for purifying river water, stacking gabion gabion nets on a plain soil compaction layer, and filling the lower part of the gabion gabion net with stones to form a stone layer, The water purification slow-release agent is packaged in a fiber non-woven plastic bag and then filled with the remaining space of the gabion mesh. After that, the opening is locked and sealed with a spiral iron wire, and the fiber non-woven plastic bag is regularly replaced. By sealing and filling the slow-release agent into the gabion gabion net, the invention can strengthen the protection of the river bank and slope, and at the same time realize the early implementation of river water purification during the flood period, and ensure the continuity and longevity of the purification effect. , to achieve the effect of purifying the water quality of the river during the flood period, and greatly reduce the engineering difficulty and manpower and material resources, have a low impact on the surrounding environment, and have a positive ecological environment effect. |
