[0028] A simulation device for the effect of vegetation on reducing emission of gas pollutants, the simulation device includes a lighting device, a humidity setting device, a temperature setting device, a vegetation incubator and a control device;

[0029] Vegetation incubator 1 wall is provided with sampling port 3 and sampling port 10, and sampling port 3 connects gaseous pollution source 4 through a sampling air pump 2 and air intake pipeline; Humidity setting device comprises water tank 6, water pump 8 and nozzle 9, and water tank The water pump 8 and the water inlet pipeline pass into the water outlet provided in the vegetation cultivation box 1, and the water outlet place is provided with a nozzle 9; The illumination device 5 is arranged on the top of the vegetation cultivation chamber 1, and the illumination installation 5 is provided with more than two light sources; The device is connected with the air pump 2, the lighting device 5, the humidity setting device, and the...

Embodiment 2

[0036] Optimized on the basis of Example 1.

[0037] The vegetation cultivation box 1 also includes a blast device connected with the control device. The blower device is also connected with the power supply and the programmable controller. The power supply supplies voltage to the blowing device, and the programmable controller controls the working condition of the blowing device, thereby adjusting the air flow in the vegetation cultivation box 1 and more realistically simulating the actual natural environment.

Embodiment 3

[0039] A method for realizing a simulation device for the effect of vegetation on reducing emissions of gas pollutants, the method comprising the following steps:

[0040] Step 1: Place the experimental vegetation on the plate, open the upper cover of the vegetation incubator, put the plate with the experimental vegetation into the incubator, and the wall of the incubator has multiple inlets from top to bottom And the sampling port is covered by the experimental vegetation, smear silicon grease on the upper cover of the incubator and the sub-port or the female port of the bottom case, and then close the upper cover and the bottom case;

[0041] Step 2: Turn on the power supply of the control device and select the automatic or manual control mode;

[0042]Step 3: In the selected working mode, connect the sampling gas pump to send the pollution source gas to the sampling port set on the wall of the incubator; then simulate the site conditions of the garbage dump to control the w...

Abstract

The invention is a device and method for simulating the emission reduction effect of vegetation on gas pollutants. The simulation device includes an illumination device, a humidity setting device, a temperature setting device, a vegetation incubator and a control device; the wall of the vegetation incubator is provided with a sampling port and a sampling port, and the sampling port is connected to a gaseous pollution source through a sampling air pump and an air intake pipeline; The humidity setting device includes a water tank, a water pump and a nozzle. The water tank is connected to the water outlet provided in the vegetation cultivation box through the water pump and the water inlet pipeline, and the water outlet is provided with a nozzle; More than one light source; the control device is connected to the air pump, lighting device, humidity setting device, and temperature setting device to realize the control of air intake, illuminance, humidity and temperature. The invention provides a real, reasonable and economical simulation device for vegetation to absorb gaseous pollutants, which can provide a platform for the pollution reduction effect test before large-scale vegetation construction by covering the end of the landfill site.

Description

technical field [0001] The invention relates to the field of environmental science experiment equipment, in particular to a device and method for simulating the effect of vegetation on reducing the emission of gas pollutants. Background technique [0002] Landfill is the final disposal site of domestic waste, and landfill treatment is currently the main treatment method for domestic waste in my country. The release of gaseous pollutants from landfills has caused relatively serious environmental pollution, especially the odorous compounds therein. Moreover, conventional closure and covering measures cannot prevent the release of gaseous pollutants. There are two common covering methods at present. One is compressed soil lining, which has a good waterproof effect but has a controlling effect on the escape of landfill gas from garbage dumps. very limited. The second is to cover temporarily or intermediately with HDPE film. Since the heat insulation effect of HDPE film is weak...
