Abstract

The invention relates to an integrated facility for restoring the water environment of a low-flow-velocity hardened urban river. The integrated facility comprises a front flow-limiting baffle plate, a front overflow baffle plate, an upper limit water-passing baffle plate, suspended filler, a lower limit water-passing baffle plate, an air blower, an aeration pipeline, an aeration head, a rear flow-limiting baffle plate, a rear overflow baffle plate, a sludge storage hopper, a front vertical water-passing baffle plate, a meadow, a rear vertical water-passing baffle plate, a sludge discharge pipe and a sludge discharge pump. The integrated facility is simple in structure, convenient to assemble and disassemble, low in cost, simple and convenient to operate, time-saving, labor-saving, high in efficiency and suitable for popularization and application. Facilities are reasonably distributed at multiple points in the low-flow-velocity and hardened urban river according to the water pollution degree, and efficient reinforced restoration of the water environment can be achieved.

Description

technical field [0001] The invention relates to the technical field of water environment restoration facilities, in particular to an integrated facility for water environment restoration of low-velocity hardened urban rivers. Background technique [0002] With the expansion of my country's cities and the intensification of pollution discharge, the current situation of urban water environment is deteriorating. Among them, urban river water pollution is the most typical, and it is difficult to control it. The reason is that with the advancement of urban infrastructure construction, the population density of river basins has increased, and the river slopes have been transformed into hardened steep slopes. The biological niches that use natural rivers as habitats have been continuously occupied, and the original purification ability of rivers has gradually been lost. Urban rivers present the characteristics of slope hardening, low water flow velocity, high pollution load, and d...
