Selenium polluted river water governance device

Abstract

The invention discloses a selenium polluted river water governance device which comprises an activated sludge adding device, a magnetic field generating device and an intelligent controller. The activated sludge adding device comprises a water pump, an activated sludge acclimation tank and an activated sludge discharge pipe. One end of the water pump is connected with the activated sludge acclimation tank, and the other end of the water pump is connected with the activated sludge discharge pipe. Selenium addicted microorganisms are cultured inside the activated sludge acclimation tank. The magnetic field generating device comprises a magnetic field tester, a power source, a transformer, an iron core and a spiral coil. The iron core is wound by the spiral coil. The spiral coil is connected with the transformer. The transformer is connected with the power source. The induction end of the magnetic field tester is arranged inside river water, the other end of the magnetic field tester is connected with the intelligent controller, and the spiral coil is arranged on the two sides and the bottom of the river water. The device is simple in structure, a weak-change magnetic field is applied to riverway sludge area microorganisms, and biochemical reactions and magnetobiological effects are performed inside the riverway at the same time, so that the selenium adsorption and degradation performance of microorganisms is enhanced, and no other chemical reagents need to be added.

Description

technical field [0001] The invention relates to the field of river water purification, in particular to equipment for treating selenium-polluted river water. Background technique [0002] Selenium is used in the electronics industry to make selenium rectifiers; in the glass industry, it is used as a fading agent and coloring agent. There is a large amount of selenium contained in the wastewater discharged from electronics factories and glass industries, and these wastewaters are discharged into rivers, which will cause serious pollution. Selenium is a non-metallic element and an essential trace element for humans and animals. Trace amounts of selenium can prevent cancer and protect the liver. However, if the body absorbs too much selenium, it will cause poisoning and cause gastrointestinal disorders. [0003] According to the survey, nearly 50% of the 700 important rivers in China, and more than 90% of the waters along the rivers have been polluted. In biological treatmen...

However, if the body absorbs too much selenium, it will lead to poisoning and cause gastrointestinal disorders.

[0003] According to the survey, nearly 50% of the 700 important rivers in China, and more than 90% of the waters along the rivers have been polluted. Biological treatment, however, temperature has an important impact on the growth, reproduction, metabolism, species distribution and population number of microorganisms, which in turn affects the efficiency of sewage treatment
