Problems solved by technology

[0004] Now the Environmental Protection Agency often conducts sampling and spot checks on the sewage discharged by chemical enterprises, and also conducts sampling and spot checks on the waters or seas where the sewage is discharged. However, when sampling, it is often only sampled on the water surface, often ignoring underwater sampling, and the storage device is not very good after sampling. Improve the partial volatilization of petroleum hydrocarbons and benzene series in water samples, causing deviations in the data of pollutant detection and evaluation

Embodiment 1

[0033] Such as Figure 1-7 Shown, a kind of in-situ preservation system of benzene series in water body, comprises:

[0034] Water surface collection module 200: used to collect water surface water samples and save them by the sewage collection and storage device 5;

[0035] Bottom collection module 300: used to collect bottom water samples and store them in the sewage collection and storage device 5;

[0036] Control module 100: used to control the water surface collection module 200 and the bottom water collection module 300 for water sample collection and information acquisition;

[0037]The sewage collection and storage device 5 includes a pile box body 501, the front and rear ends of the box body 501 are respectively connected with a water inlet pipe 502 and a water outlet pipe 503, and the box body 501 is provided with a water inlet chamber 507 and a filter chamber 504 sequentially from the water inlet end to the water outlet end , precipitation chamber 505 and water s...

Embodiment 2

[0050] When the system for in-situ storage of benzene series in a water body of the present invention is actually used: the acquisition module 200 and the underwater acquisition module 300 are respectively placed in the same water area, and the lifting device 8 puts the permeable tank 12 into the bottom of the water body, and then the water pump 4 controls the water body. The water and sediment at the bottom are pumped into the sewage collection and storage device 5. After the collection is completed, the Austrian equipment 8 is started to lift the water-permeable tank 12, and the water pump 4 on the floating block 7 directly pumps water to the water surface and sends the water body into the sewage collection In the storage device 5, after the collection is completed, the sewage collection storage device 5 in the collection module 200 and the underwater collection module 300 is sent to the laboratory for analysis. During the water sample collection process, the GPS6 in the colle...

Abstract

The invention provides an in-situ preservation system of water benzene series. The in-situ preservation system comprises a water surface acquisition module, a water bottom acquisition module, a control module and a sewage acquisition storage device, wherein the water surface acquisition module is used for acquiring a water surface sample, the water surface sample is stored by the sewage acquisition storage device, the water bottom acquisition module is used for acquiring a water bottom sample, the water bottom sample is stored by the sewage acquisition storage device, the control module is used for controlling the water surface acquisition module and the water bottom acquisition module and performing water sample acquisition and information acquisition, the sewage acquisition storage device comprises a pile box, a water inlet pipe and a water outlet pipe are respectively connected with a front end and rear end of the box, and a water inlet chamber, a filtering chamber, a precipitationchamber and a water storage chamber are sequentially arranged in the box from a water inlet end and a water outlet end. By the in-situ preservation system, water sample acquisition of a water surfaceand / or a water bottom of a monitoring water region can be achieved, the water samples are stored, acquisition information accuracy is stored, and the problem that petroleum hydrocarbon and the benzeneseries in the water sample volatile is solved.

Description

technical field [0001] The invention belongs to the field of sewage collection and storage equipment, and in particular relates to an in-situ storage system for benzene series in water. Background technique [0002] Atmospheric VOCs emissions from the petrochemical industry involve eight types of pollutants: aromatic hydrocarbons, halogenated hydrocarbons, alkanes, ketones, alcohols, and phenols, among which aromatic hydrocarbons and halogenated hydrocarbons are the primary VOCs pollutant categories in the petrochemical industry Among them, the detection rate of chloroform, p-(m)xylene, undecane, benzene, benzaldehyde, p-dichlorobenzene, cyclohexanone, and o-xylene is relatively high. [0003] At present, there are not many studies on the discharge of characteristic pollutants in the sea area of ​​the petrochemical industry. Although the current petrochemical industry is also undergoing enterprise transformation, it is committed to environmental protection and safety first. ...
