Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an automatic dosing device for water treatment. Background Art

[0002] Industrial wastewater refers to wastewater containing harmful substances discharged during the industrial production process. If not treated in time, it will cause great harm to the environment and human health. Therefore, it is very important to treat industrial wastewater. The impurities in industrial wastewater include floating objects on the water surface, suspended objects in the water, sinkable objects at the bottom, and solid substances dissolved in the water. According to the hazard characteristics, pollutants in industrial wastewater can be divided into floating objects, suspended solids, petroleum, aerobic organic matter, refractory organic matter, plant nutrients, heavy metals, acids and alkalis, radioactive pollutants, pathogens, thermal pollution, etc. The prior art uses a purifier to react with impurities in wastewater to purify water quality. For example, the patent with the announcement number "CN216458254U" proposes an automatic dosing device for water treatment. By setting a timing structure, when using a dosing box to dosing, the use of a solenoid valve, a control panel and a timer can achieve automatic and accurate control of the dosing time. For example, the patent with the announcement number "CN 213976996 U" proposes an automatic dosing device for water treatment. By controlling the dosing pump and the solenoid control valve through the control box, the time and accuracy of drug addition can be accurately controlled. The above two prior arts further enhance the accuracy of the dosing link.

[0003] However, industrial wastewater also contains floating matter and suspended matter, among which inorganic floating matter or suspended matter mainly refers to granular or flaky materials such as gravel, silt, dust, iron filings, and metal residues that are floating or suspended in sewage, most of which come from domestic sewage, initial rainwater, surface water for washing, and industrial wastewater such as coal washing, ore dressing, and metallurgy. Inorganic floating matter or suspended matter itself is generally non-toxic, but it can absorb organic poisons, heavy metals, etc. to form more harmful composite pollutants; organic floating matter and suspended matter mainly refer to long strips and block materials such as fibers, plastic products, branches and wood blocks, and paper products that are floating or suspended in sewage, most of which come from domestic sewage, initial rainwater, and surface water for washing. After sewage with a high content of inorganic suspended matter enters the treatment plant, it will increase the burden of sedimentation tanks and sedimentation tanks, and even cause siltation, reduce the effective volume of the tank body, and affect the treatment effect; after organic suspended matter enters the water treatment system, it will have an adverse effect on the normal operation of various equipment in the water treatment system. The above two existing technologies are unable to treat floating matter and suspended matter in industrial wastewater. Utility Model Content
