The invention provides a method for repairing
eutrophication water by utilizing aquatic plants and microorganisms together. The method specifically comprises the following steps: a, river channel cleaning: removing various floating foreign matters on water surface through manual salvaging, and reserving volunteer plants of the water; b,
aquatic plant-
microorganism combined purification sections: adopting a stereoscopic structure of an
aquatic plant floating
bed, reasonably distributing in the water, and forming a zonal
plant net wall having certain width and traversing a river channel; c, aerobic
microorganism repairing sections: utilizing microbial
flora, distributing in downstream water zones of the
aquatic plant-
microorganism combined purification sections after
domestication, moderately aerating, and increasing the dissolved
oxygen in the water of the river channel; d, sequentially distributing the aquatic
plant-microorganism combined purification sections and the aerobic microorganism repairing sections along the river channel in a reciprocating and serial connection way, and forming a purification
system of continuous batches. According to the method provided by the invention, the
self cleaning capacity of the water can be improved while the
water quality is purified to the maximum, the effect of beautifying the water is also integrated, secondary
pollution cannot be generated, and the characteristics of environment protection,
energy conservation and reclamation are integrated.
