An ecological interception control device and interception control method for agricultural non-point source pollution

Abstract

The invention discloses an ecological interception control device and interception control method for agricultural non-point source pollution. The device is installed at the rear of the interception channel body; there are two sets of collection tanks, which are respectively located at the positions corresponding to the inner wall of the interception channel and the position of the pre-interception device; the pre-interception device includes side plates, interception drums, and sewage tanks; the ecological interception device consists of planting It is composed of carrying net and plant planter. The device of the invention can effectively clean up the floating sundries in the agricultural waste water, and is energy-saving and environment-friendly.

Description

technical field [0001] The invention relates to the technical field of agricultural non-point source treatment, in particular to an ecological interception control device and interception control method for agricultural non-point source pollution. 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 on both sides of a large number of...

Problems solved by technology

[0003] However, the interception devices used in the prior art for agricultural non-point source pollution are often prone to clogging after being put into use in the medium and long term through the interception treatment of the interception net, which affects the subsequent interception effect and has a negative impact on the size of the intercepted water flow. impact, there are also some devices in the existing technology that can regularly clean the interception net, but its high energy consumption is not conducive to the use in rural areas. At the same time, the use of ecological planting for agricultural non-point source treatment has the advantages of green environmental protection

However, due to the unevenness of floating debris in the water flow, it is easy to gather at some aquatic plants at fixed points, resulting in slow growth or even death of aquatic plants; Dealing with agricultural non-point source pollution
