A heavy metal adsorption purification system

Abstract

The invention discloses a heavy metal adsorption and purification system, which includes a sedimentation tank, a filter box, a first filter screen, a support base, a first water pump, a water suction pipe and a drain pipe, the first filter screen is fixedly arranged in the filter box, and the A quantitative dosing structure is connected to the outside and back of the sedimentation tank, and an adsorption structure is installed in the filter box. The present invention relates to the technical field of wastewater treatment equipment. The quantitative dosing structure will automatically discharge the medicine into the sedimentation tank through the second water pump. When the medicine When the discharge reaches the preset value, the flowmeter will control the second water pump to shut down through the quantitative controller, and the heavy metals in the wastewater in the sedimentation tank will react with the drug. After the reaction, the heavy metals in the wastewater will precipitate, and the quantitative drug delivery structure The setting replaces the traditional method of manual dosing by staff, which reduces the labor intensity of staff and increases the accuracy of dosing.

Description

technical field [0001] The invention relates to the technical field of wastewater treatment equipment, in particular to a heavy metal adsorption purification system. Background technique [0002] Water resources are an indispensable natural resource for human life and an environmental resource for the survival of living things. In recent years, with the enhancement of people's health awareness, the degree of attention to water resource protection and water pollution control has also increased. Moreover, with the rapid development of the economy, environmental pollution has intensified, especially the amount of heavy metal-containing wastewater discharged into the environment has increased, leading to the increasingly serious problem of heavy metal pollution in my country. In my country, lead poisoning in drinking water in Yancheng, Jiangsu, and chromium pollution in Qujing, Yunnan, broke out continuously. , Guangxi Liuzhou chromium pollution and many other serious heavy meta...

Problems solved by technology

Generally, general organic pollutants can be degraded and purified physically, chemically or biologically in nature to reduce or eliminate their hazards; however, heavy metal pollutants cannot be biodegraded after entering the environment and will participate in the food chain cycle, eventually leading to Accumulate in organisms and destroy the normal physiological metabolism of organisms, which will cause many environmental and health problems. At present, the most commonly used adsorption devices for heavy metal ions in water are incomplete in removing heavy metals, and the effect of adsorption and purification of heavy metals is not good. The filter screen is often clogged and needs to be cleaned manually, which greatly reduces the cleaning efficiency of the adsorption device. In view of this, in view of the above problems, in-depth research led to this case.
