Water quality processing system of diversion and drainage river channel

Abstract

The invention provides a water quality processing system of a diversion and drainage river channel. The water quality processing system is arranged on the diversion and drainage river channel between an external water body and a receiving water body, and comprises a diversion and drainage unit, a natural settlement unit and an interception and filtration processing unit, wherein the diversion and drainage unit, the natural settlement unit and the interception and filtration processing unit are sequentially arranged in a water diversion direction. The diversion and drainage unit is arranged at a water diversion port and is provided with a two-way pump and sluice. The cross section of the natural settlement unit is wider than that of the diversion and drainage river channel and is longer than that of the interception and filtration processing unit, and a bottom surface of the natural settlement unit is lower than that of the diversion and drainage river channel. The interception and filtration processing unit comprises multiple interception and filtration processing devices with filtration stuffing inside; in the length direction of the diversion and drainage river channel, the interception and filtration processing devices are parallel; in the width direction of the diversion and drainage river channel, the interception and filtration processing devices are sequentially overlapped; in the depth direction of the diversion and drainage river channel, the interception and filtration processing devices are sequentially staggered. The system can be used for purifying and processing the introduced water body comprehensively in the length, width and depth directions of the diversion and drainage river channel in a three-dimensional manner and effectively purifies the introduced water body.

Description

technical field [0001] The invention belongs to the technical field of ecological environment engineering, and in particular relates to a water quality treatment system for diversion and drainage channels. Background technique [0002] At present, some relatively closed water bodies such as lakes and rivers are polluted to varying degrees. While controlling pollution sources, diverting water from outside to increase the water exchange and hydrodynamic conditions of receiving water bodies has become an important control method. However, in practical applications, when the amount of water in the external water body is sufficient, the time and efficiency of water diversion are often limited by the water quality of the external water body. For example, when the sediment content of the external water body is high, diverting water into the receiving water body will reduce the transparency of the receiving water body, thereby affecting the health of the ecosystem of the receiving w...

AI Technical Summary

Problems solved by technology

[0003] The general sedimentation treatment system uses sedimentation ditch along the way, surface flow wetland interception system or filtration equipment, etc., but these systems all have certain deficiencies: the treatment efficiency of the sedimentation ditch is relatively low, and small particles and other pollutants cannot be removed; The treatment efficiency of the wetland interception system is relatively good, but the area is relatively large; the treatment efficiency of the filter equipment is relatively good, but it is not suitable for large-flow water diversion, and the energy consumption is high

The existing sedimentation treatment system technologies for water diversion have certain limitations, which limit the timeliness of water diversion to a certain extent
