In the past 10 years, the eutrophication of rivers, lakes and reservoirs in our country has been serious, and the phenomenon of "water bloom" has occurred from time to time, and it is gradually deteriorating. Sudden water pollution accidents refer to serious accidents in which a large amount of pollutants are discharged in an instant or in a short period of time, causing serious pollution and damage to the water environment, and causing heavy losses to people's lives and national property. Different from general environmental pollution, it has the characteristics of sudden occurrence, rapid spread and serious harm, and some pollutants are even unknown. All kinds of sudden accidents and abnormal operation of chemical plants will lead to unpredictable water pollution accidents. The accidental leakage of toxic and dangerous chemicals into the water environment will not only cause great harm to human beings, pose a threat to the survival of organisms, but also destroy the balance of the water ecosystem. Effective water quality early warning technology can not only reduce the damage of sudden environmental pollutants to the water ecological balance, but also help to ensure the safety of human drinking water.

Test object: the experimental group is the water quality situation of plant algae, zooplankton and fish after the device of the present invention is cultivated for 8 days, and embodiment 1, embodiment 2 and embodiment 3 of the present invention are respectively set as experimental group 1, experimental group 2, The experimental group 3 and the control group are the water quality of other common devices after 8 days of cultivation and the water quality of plant algae, zooplankton and fish. Except for the different experimental devices, the initial culture density and water quality were the same and comparable.

Test method: Collect 40 water samples from the control group, experimental group 1, experimental group 2, and experimental group 3 respectively, with 100ml of water samples in each group, and use the water quality detector to detect the average value of each index of the water samples;

Table 1 Average value of water quality indicators

As can be seen from Table 1, the water quality of the device of the present invention reaches the standard after 8 days of automatic cultivation, meeting the living conditions of animals and plants.

The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: it can still be described in the foregoing embodiments Modifications are made to the technical solutions, or equivalent replacements are made to some of the technical features; these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
