Hydrolysis device adopting multi-point flow-ascending type water feeding and distributing and technology

Abstract

The invention discloses a hydrolysis device adopting multi-point flow-ascending type water feeding and distributing and a technology. The hydrolysis device comprises a water feeding pipe and a hydrolysis pool, flow-ascending type water distributing devices are arranged at the top of the hydrolysis pool through multi-point distribution, and each flow-ascending type water distributing device is connected with the water feeding pipe through a corresponding water feeding branched pipe and comprises a water equalizing barrel, a water feeding barrel, water equalizing holes and a water distributing pipe, wherein the water feeding barrel is located in the center of the water equalizing barrel, the water feeding branched pipe penetrates through the bottom or the side wall of the water equalizing barrel to be connected into the water feeding barrel, and water overflows from the top of the water feeding barrel; the water equalizing holes are located in the bottom of the water equalizing barrel and surround the water feeding barrel uniformly; the upper end of the water distributing pipe is connected with a corresponding water distributing hole, the lower end of the water distributing pipe extends downwards to the bottom of the hydrolysis pool, and water distributing holes are uniformly distributed in the water distributing pipe. The hydrolysis device is applied to realizing the equalization of water feeding for the flow-ascending type hydrolysis pool, effective utilization of a reaction region of the flow-ascending type hydrolysis pool is made maximum, and the effect of sewage treatment is optimal.

Description

technical field [0001] The invention relates to the technical field of materials and environmental engineering, in particular to a multi-point upflow water distribution hydrolysis process. Background technique [0002] The upflow sludge bed hydrolysis tank is a kind of sludge hydrolysis and acidification process, which evolved from the upflow anaerobic sludge bed, and the operation mode is changed to partial anaerobic, that is, the reaction is controlled in the hydrolysis and acidification stages. The process of treating urban sewage has the characteristics of short residence time, no need for fillers and mechanical stirring devices. And through the dual functions of physical retention and biodegradation of the suspended sludge layer, a good decontamination effect is achieved, which has advantages that other hydrolysis processes cannot match. [0003] The treatment effect of the upflow hydrolysis biological treatment tank (hereinafter referred to as the hydrolysis tank) dep...

AI Technical Summary

Problems solved by technology

[0005] Although the development of water distributors in hydrolysis tanks is relatively mature, the uniformity of water distribution in hydrolysis tanks still attracts the attention of the industry

Due to the long residence time and large pool capacity of the hydrolysis tank, the uniformity of sewage in and out must be considered; if the water distribution in the hydrolysis tank is not uniform, the reaction area cannot be fully utilized, which will affect the treatment effect
