Description

Chemical industry discharges sewage sampling detection device

Technical Field

The invention relates to the field of chemical wastewater, in particular to a chemical wastewater sampling and detecting device.

Background

There are various kinds of aquatic animals and plants in nature, the organisms and water, and the organisms and organisms exchange complex substances and energy, a dynamic balance relationship is maintained quantitatively, but under the influence of human activities, the balance is destroyed, when human discharges pollutants into water, some beneficial aquatic organisms are poisoned and die, some pollution-resistant aquatic organisms are propagated intensively, oxygen dissolved in water is consumed in a large amount, so that the beneficial aquatic organisms are forced to live in other places due to oxygen deficiency, or die, especially some toxic elements are difficult to dissolve in water and easy to accumulate in organisms, and cause great harm to human beings, such as low mercury content in water, high mercury content in aquatic organisms and high mercury content in fish bodies, and supposing that the mercury concentration in water is 1, the mercury concentration in benthic organisms (small organisms living in bottom mud of water) in aquatic organisms is 700, and the mercury concentration in the fish body is as high as 860, so that the water body is polluted, on one hand, the balance between organisms and water and between organisms is damaged, on the other hand, some toxic substances are continuously transferred and enriched, and finally, the health and the life of human beings are endangered.

Environmental protection is valued, the market of environmental monitoring is continuously expanded along with the environmental protection, the traditional environmental monitoring station cannot completely meet the social environmental monitoring requirement, the country gradually opens the channel of the environmental monitoring field, and for professional environmental monitoring, a social environmental detection mechanism with CMA environmental detection qualification is used as the vitality of third-party detection and becomes the first choice of environmental monitoring with social entrustment property.

At present, when a chemical emission sewage sampling detection device performs sampling detection on chemical emission sewage, a sampling bottle needs to be fixed through a rope, a sample is obtained from a ditch and then is transported to a laboratory for detection, but partial components (such as oxygen content, ammonia content and the like) of the sample are changed in the transportation process, so that the detection value of the sample is not consistent with the actual value, and the detection effect is influenced; when the traditional chemical discharged sewage sampling detection device samples sewage at different depths, only one depth of sewage can be sampled at one time, and sampling personnel often need to sample the sewage at different depths through the sampling bottle for one time, but the method has low efficiency and cannot accurately grasp the depth of the sewage during sampling; meanwhile, when the traditional chemical wastewater discharge sampling detection device is used for sampling wastewater, the traditional chemical wastewater discharge sampling detection device is used for detecting wastewater generally, and does not sample sludge at the bottom of the wastewater, so that a user who is inconvenient to use can detect the wastewater comprehensively.
