Device for movably testing pollutant intercepting efficiency of riverside band

Abstract

The invention provides a device for movably testing the pollutant intercepting efficiency of a riverside band, and belongs to the technical field of environment monitoring. The device comprises a water distributing reservoir, a flow generating tank, lateral water stop plates, underground seepage flow collecting devices, surface runoff collecting devices, a water pump, water pipes and a flow generating spraying head. The water distributing reservoir is connected with the flow generating tank through the corresponding water pipe. A switch is arranged at the portion where the water distributing reservoir is connected with the corresponding water pipe. The lateral water stop plates are connected with the two ends of the flow generating tank and are perpendicular to the flow generating tank. The multiple underground seepage flow collecting devices and the multiple surface runoff collecting devices are arranged between the two lateral water stop plates according to requirements. The water pump pumps river water into the water distributing reservoir through the corresponding water pipe. The water distributing reservoir is connected with the flow generating spraying head through the corresponding water pipe. The device is simple in structure and convenient to move and can be assembled according to requirements, and disturbance in soil and vegetation of a test site is small; even flow is generated through the water pump, the flow generating tank and the flow generating spraying head, and flow control can be carried out according to experimental requirements.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a mobile device for measuring the efficiency of intercepting pollutants in a riverside zone. Background technique [0002] Non-point source pollution has been paid more and more attention by the state due to its wide pollution range and large impact area. The construction of riverside belts is considered to be an important means to remove non-point source pollution. The riverside belt refers to various vegetation belts built along the banks of rivers, lakes, streams and valleys. It is an important part of the small watershed ecosystem of rivers entering the lake and the last barrier to protect the water environment of rivers and lakes. It can effectively control the low-pollution water entering the river, and is suitable for water and soil conservation, control of non-point source pollution protection and improvement of river water quality. [0003] There are ma...
