Ecological interception device and method for agricultural non-point source pollution remediation

Abstract

The invention discloses an ecological interception device and method for agricultural non-point source pollution remediation. The device comprises an interception channel body, a pretreatment assembly, a buoy interception assembly and an ecological interception assembly. The pretreatment assembly comprises an intercepting grid and a collecting box, wherein the intercepting grid is arranged at thehead end of the intercepting channel body, the collecting box is arranged on the outer wall of the intercepting channel body, and the buoy intercepting assembly comprises an installation cover plate,an adsorption cotton cylinder and a sliding installation block; the adsorption cotton cylinder is clamped to the installation cover plate, and the sliding installation block is clamped to the intercepting channel body and then clamped to the buoy intercepting assembly; the ecological interception assembly comprises a filler frame, a planting frame and an aquatic plant planter, the planting frame is clamped on the filler frame, and the aquatic plant planter is arranged on the planting frame. According to the device and method, the impurities in a water body are intercepted and collected throughthe pretreatment assembly, wherein organic pollutants in the water body are adsorbed through the buoy interception assembly, and the organic pollutants in the water body are adsorbed and fixed through the ecological interception assembly. The device is reasonable in structural design, high in pollutant intercepting efficiency and suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of non-point source pollution restoration equipment, in particular to an ecological interception device and method for agricultural non-point source pollution restoration. Background technique [0002] Agricultural non-point source pollution refers to dissolved or solid pollutants in rural life and agricultural production activities, such as organic or inorganic substances such as soil particles, nitrogen, phosphorus, pesticide heavy metals, rural poultry manure and domestic garbage in farmland , from a non-specific area, under the action of precipitation and runoff, a large amount of pollutants enter the receiving water body through farmland surface runoff, farmland drainage and underground seepage; pollution caused by rural solid waste in agricultural non-point source pollution Pollution is particularly serious. A large amount of solid waste can be seen everywhere in the flowing water sources in rural area...

Problems solved by technology

[0003] At this stage, in order to solve the pollutants floating on the river surface, most of them are intercepted on the river surface, and then the pollutants are caught artificially to keep the river surface clean and reduce the river pollution. However, the existing pollutant interception devices are widely available. The following problems: poor practicability, easy to cause secondary pollution in the process of treatment; single function, insufficient interception of pollutants; not stable operation of equipment, large economic investment
