Problems solved by technology

This method is classic and reliable, and is the current national standard method, but it has disadvantages such as complicated operation, time-consuming, and inability to monitor continuously
[0007] β-ray weighing is to use β-rays to irradiate the measured particles. The β-rays will collide with the particles and lose energy. In the case of low energy, the degree of absorption of β-rays depends only on the quality of the medium. Compared with the changes in the intensity of β-rays before and after irradiation Amplitude can be used to calculate the quality of haze. The Chinese invention patent document with application number 201510878762.6 discloses a detection method for haze particles, using the β-ray method and light scattering method for simultaneous detection, and the method of internal reference to realize the calibration of the detection results , this method does not require a conversion process and has high measurement accuracy, but there are problems such as bulky and slow detection speed

Embodiment 1

[0048] A method for ecological environment dynamic monitoring and early warning, comprising the following steps:

[0049] 1. The external air to be tested is extracted through the sampling pump, and the external air enters the air storage chamber through the intake pipe, and is diverted to the air filter membrane through the guide tube. Filter through the filter membrane, and the tail gas that passes through the filter membrane is discharged through the outlet pipe.

[0050] A better solution is that the sampling pump and the filter pump work synchronously to complete the collection and filtration of the air to be tested, so as to improve the detection efficiency.

[0051] 2. After step 1 has been carried out for a certain period of time, stop the sampling pump and the suction filter pump, the transmission device drives the filter membrane to move, and transfers the part of the filter membrane attached to the object to be tested to the detection area, and the β-ray generator e...

Abstract

The invention relates to the field of the monitoring, and provides an ecological environment dynamic monitoring and early-warning method. The method comprises the following steps: collecting externalenvironment to-be-monitored air through a sampling pump, depositing atmospheric suspended matters on a filter membrane through a suction filter pump, wherein the filter membrane is quickly transferredto the beta-ray detector through a transmission device, the beta-ray detector determines the particulate matter mass adsorbed to the filter membrane, a flowmeter meters the collected air volume, andthe controller determines the current haze concentration, and predicts the haze concentration of the future time according to the haze concentration change; the filter membrane is a composite thin-film modified by adopting inorganic material, and has high tension strength. Through the monitoring method disclosed by the invention, the dynamic monitoring and early-warning on the haze pollution in the ecological environment can be realized through the quick and automatic detection on the atmospheric pollutants.

Description

technical field [0001] The invention relates to the field of environmental monitoring, in particular to a method for dynamic monitoring and early warning of an ecological environment. Background technique [0002] Ecological environment refers to the general term for the quantity and quality of various natural resources that affect human survival and development. It is related to the sustainable development of social economy. , the damage to the natural environment and the various negative feedback effects of pollution that endanger human existence are prominently manifested in air pollution, soil erosion, and vegetation degradation. [0003] In recent years, smog weather has occurred in areas with high population density, especially in large and medium-sized cities, which has seriously threatened the health of the people. Smog is a general expression of the excessive content of various suspended particles in the atmosphere and an intuitive indicator of air pollution. Perfo...
