Embodiment

[0032] Step 1: Desilt the bottom of the river and ditches, widen the river, build a temporary retaining dam in the construction area on one side of the river, use a pump to drain the water in the construction area, and use a suction pump to drain the silt in the river to Clean the river bottom silt on the bank or use an excavator to pile it up to the bank to dry; wait for the silt on one side of the river to be cleaned up, and then clean up the river bottom silt on the other side in the same way;

[0033] Step 2: Build a stepped dam in the river or ditch from upstream to downstream, using brick and stone stacking, cast-in-place concrete or reinforced concrete to build the dam, leaving 3-5 water outlets in the dam, and the horizontal elevation of the water outlet Consistent, with a width of 30-50cm, choose 0-50cm, 50-80cm, 150-180cm three kinds of yellow wax stones to be stacked staggeredly on the front, top and back water surfaces of the dam. There are gaps or holes between the...

Abstract

The invention discloses a method for purifying water quality by constructing biodiversity in shallow water channels and ditches. The method comprises the steps of constructing a stepped water retaining dam, constructing natural revetments on both sides of a river bank and planting plants on slope soil layers on both sides of the river bank. According to the method, by utilizing processes such as physics, biology, water conservancy and the like, the water quality purification effect is remarkable and stable, and at the same time, through the combation with a beautification effect of artificialnatural landscape, the comfortable, safe and beautiful water environment concepts are fully embodied, and the method has a broad application prospect.

Description

technical field [0001] The invention belongs to the technical field of ecological environment management, and in particular relates to a method for purifying water quality of shallow water channels and ditches. Background technique [0002] Urban rivers and ditches are essential elements for the survival and development of cities. They play a very important role in the economic development and ecological environment of the surrounding areas of the city. The disasters that may be caused to the city are becoming more and more serious. Therefore, the improvement of the urban water environment has been paid more and more attention by all walks of life. People have transformed from the traditional flood control and drainage water conservancy construction to the concept of "comfortable, safe and beautiful" water environment. . [0003] However, for a long time there has been a common problem that the construction of urban rivers lags behind the speed of urban development. Urban r...
