Example Embodiment

[0024] Embodiment 1 A kind of collection device of volatile gas in black and odorous water body

[0025] like Figure 1-Figure 3 As shown, a device for collecting volatile gases in black and odorous water is structured as follows:

[0026] It includes a column (1), and the column (1) is provided with a number of holes.

[0027] Several layers of metal frames (2) are arranged on the upright column (1), and five layers are arranged in this embodiment. Preferably, the optimal scale size of the metal frame (2) is 30cm×12.5cm×2cm, and the metal frame (2) is made of corrosion-resistant material.

[0028] A silicone resin tube (3) is installed in each metal frame (2), and a support spring (4) is inserted into the silicone resin tube (3). A silicone resin tube (3) is coiled in an S shape in the metal frame (2), so that the volatile gas in the black and odorous water body can be collected to the maximum and stably. The silicone resin tube (3) is made of silicone resin, which is a p...

Example Embodiment

[0031] Embodiment 2 A kind of detection method of volatile gas in black and odorous water body

[0032] Adopt the collection device of volatile gas in the black and odorous water body of embodiment 1, the method is as follows:

[0033] 1) According to the needs of collecting volatile gases of different depths in the black and odorous water body, after adjusting the distance between several layers of metal frames (2), fix the metal frame (2) and the column (1) by bolts;

[0034] 2) Place the bottom metal frame (2) on the interface between the black and odorous water bottom mud and the water body, and then fix the periphery of the collection device with steel plates to effectively prevent the collection device from being disturbed or damaged by other external conditions, and place it for 10-20 sky;

[0035] 3) When collecting volatile gases in black and odorous water bodies, connect the pipeline connected with the silicone resin tube (3) in the metal frame (2) of the layer corr...

Abstract

The invention relates to a collection device and detection method for volatile gas in a black and odorous water body. The device comprises a stand column and is characterized in that a plurality of layers of metal frames are arranged on the stand column, silicon resin pipes are installed in the metal frames, supporting springs are inserted into the silicon resin pipes, two ports of each silicon resin pipe are connected with one ends of two stainless steel pipes on the outer sides of the metal frames respectively, and the other ends of the stainless steel pipes are in sealed connection with oneends of plastic pipes respectively; the other ends of the two plastic pipes are connected with a first connector and a second connector of a three-way valve respectively, and a third connector of thethree-way valve is connected with a drying pipe and a flowmeter through pipelines. Volatile gas generated in the bottom mud can be measured, and the volatile gas generated in the black and odorous water body can be collected more comprehensively.

Description

technical field [0001] The invention belongs to the field of environmental technology, and relates to a collection device for volatile gas in black and odorous water bodies and a detection method thereof. Background technique [0002] In recent years, due to the acceleration of the industrialization process, the discharge of wastewater has increased year by year. Among various types of wastewater, black and odorous water bodies are the most difficult to treat. After a large number of studies, it has been shown that the mechanism of black odor in water is basically the same. It is caused by the lack of oxygen in the water and the decay of organic matter. When a large number of organic pollutants enter the water body, under the biochemical action of aerobic microorganisms, a large amount of oxygen in the water body is consumed, and the water body is transformed into an anoxic state, resulting in the proliferation of anaerobic bacteria, and the decay, decomposition and ferment...
