Abstract

The invention relates to a chemical dosing device for chemical phosphorus removal for sewage treatment, which comprises a main machine for adding medicine, a medicine storage tank and a medicine delivery pipe connecting the two; The main shaft in the main shaft cover, the lower end of the main shaft is provided with a spiral impeller, the output end of the motor is connected to the main machine mounting seat and fixed to the pool wall through the frame; the lower end of the main shaft cover is open, and the upper end is sealed and fixed to the main machine for installation On the seat, the inner cavity of the main shaft cover forms a cavity with the upper end sealed and the lower end open. The lower half of the main shaft cover is provided with a drug suction port; It is connected to the drug suction port on the machine, and the correct drug dosing is realized through the adjustment of the vacuum degree control valve and the drug volume control valve. The present invention is different from the commonly used chemical dephosphorization method. It adopts the direct dosing of medicament, and can also use the dosing of the medicine liquid exported from the factory, which saves the complicated system of preparation and delivery of the medicine liquid, is simple and reliable, and has high practical value.

Description

technical field [0001] The invention relates to auxiliary equipment in the sewage treatment process, in particular to a chemical phosphorus removal agent dosing device. Background technique [0002] Due to the extensive use of pesticides, chemical fertilizers and phosphorus-containing detergents, the nitrogen and phosphorus content in the water body increases. Phosphorus is one of the main factors leading to eutrophication of the water body, which leads to the rapid reproduction of algae and plankton in rivers and lakes. Cause water quality to deteriorate, seriously endangering the living environment of human beings. my country's "Urban Wastewater Treatment Common Pollutants Discharge Standard" (GB18918-2002) clearly stipulates that since January 1, 2006, the first-level A discharge standard for the total phosphorus index of sewage treatment plants is 0.5mg / L. Therefore, Phosphorus removal is necessary in sewage treatment. [0003] There are mainly two methods of phosphorus...
