Wastewater treatment device capable of realizing quantitative feeding of medicinal liquid

Abstract

The invention provides a wastewater treatment device capable of realizing quantitative feeding of medicinal liquid, which includes a stirring tank, wherein the stirring tank is provided with a stirring chamber with the top opened, a plurality of medicinal liquid adding cylinders are circumferentially arranged in the stirring chamber, a medicinal liquid outlet is arranged at the bottom of each medicinal liquid adding cylinder, a quantitative medicinal liquid discharging mechanism includes a fixed ring, a toothed ring, a plurality of sealing sheets, a gear and a first driving mechanism, the central axis of the fixed ring coincides with those of the medicinal liquid outlets, the toothed ring is arranged at the outer part of the fixed ring and the central axis of the toothed ring coincides with that of the fixed ring, the plurality of sealing sheets are in circumferential uniform distribution with the center of the fixed ring as a center, one end of each sealing sheet is articulated with the fixed ring, the toothed ring is circumferentially articulated with a plurality of connecting rods, each connecting rod is articulated with one end of the corresponding sealing sheet, the gear is arranged outside the toothed ring and is engaged with the toothed ring, and the first driving mechanism is connected with the gear to drive the gear to rotate. The quantitative feeding of the medicinalliquid is achieved by setting the medicinal liquid adding cylinders and the quantitative medicinal liquid discharging mechanism, so as to achieve the best effect of wastewater treatment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a sewage treatment device for quantitatively feeding liquid medicine. Background technique [0002] The topic of water pollution, especially groundwater pollution, is constantly being brought up. As of the end of 2012, the number of enterprises in my country's sewage treatment and regeneration industry reached 213, with total assets of 84.413 billion yuan, an increase of 11.43% over 2011, and sales revenue of 23.664 billion yuan, an increase of 16.16% over 2011. The expansion speed Faster and higher level of development. [0003] The sewage treatment process needs to go through many complicated procedures and a lot of complicated equipment. Sewage treatment tanks are commonly used equipment in sewage treatment. However, when the existing sewage treatment tanks are used for solid-liquid separation of sewage, it is troublesome to add liquid medicine. , The stirring effect...
