Description

Technical Field

[0001] This utility model belongs to the technical field of sewage thickening tanks, and specifically relates to a sewage thickening tank. Background Technology

[0002] There are three main sludge thickening processes: gravity thickening, flotation thickening, and centrifugal thickening. Gravity thickening is currently the most widely used in China.

[0003] Gravity thickeners can be classified into two types according to their operation mode: intermittent and continuous.

[0004] Intermittent operation, with discontinuous sludge feeding and discharging. After entering the thickening tank, the sludge settles under gravity, with interstitial water being pushed to the surface and the thickened sludge settling. During operation, the supernatant is discharged first to free up tank space before sludge is added. Therefore, supernatant discharge pipes are installed at different concentrations at different tank depths.

[0005] In a continuous process, the sludge to be concentrated enters the thickening tank continuously through the sludge inlet pipe and guide tube in the center of the tank. The supernatant is discharged through the overflow weir. The concentrated sludge is slowly scraped into the sludge hopper at the bottom center of the tank by a sludge scraper and then discharged through the sludge discharge pipe. The sludge scraper is equipped with an agitator. The micro-vortex formed by the grid bars rotating with the scraper promotes sludge particle flocculation and creates cavities, allowing pore water and air bubbles in the sludge particles to escape, thus enhancing the thickening effect.

[0006] Currently, wastewater thickening tanks occupy a large area and are not suitable for small-area sludge thickening sites. Therefore, a wastewater thickening tank that is easy to assemble is proposed.

[0007] Therefore, in view of the shortcomings of the above-mentioned solutions in actual production and implementation, this utility model was created by making corrections and improvements, and a wastewater thickening tank is provided to solve the above-mentioned problems. Utility Model Content

[0015] Using the above scheme, the clamp is used to fix the flocculant injection pipe, and the tightness of the fastening bolts can be adjusted to allow the clamp to slide and adjust, thereby adjusting the position of the flocculant injection pipe.

[0016] In a preferred embodiment of a wastewater thickening tank, the sleeve and the mounting bracket are an integral structure, and the sleeve is inclined.

[0017] By adopting the above scheme, the inclined arrangement of the flocculant injection pipe can greatly reduce the impact of water-containing sludge.
