Variable-speed up-flow hydrolysis acidification reactor

Abstract

The invention discloses a variable-speed up-flow hydrolysis acidification reactor, which comprises a tank body. A central shaft is arranged at the center of the tank body, and the bottom of the central shaft is connected to a sewage inlet pipe and a tank bottom water distribution pipe. The top of the tank body is provided with a water distributor, the bottom of which is communicated with the central shaft. The water distributor is also connected with a reflux main pipe, the other end of which is connected to a multi-point water absorption reflux device located in the tank body. The reflux mainpipe is equipped with a flowmeter; a reflux pump is installed inside the reflux main pipe; water distribution ports are arranged on the tank bottom water distribution pipe; the tail end of each waterdistribution port is provided with a variable diameter plug; the top of the tank body is provided with an effluent catch basin; a sludge drain pipe is installed above the tank bottom water distribution pipe; and the sludge drain pipe is connected to a sludge pump outside the tank body. According to the invention, loss of activated sludge can be prevented, concentration of the effluent suspended substances is reduced, no mechanical stirring is needed, there is no power consumption, energy is saved and the environment is protected, water distribution is uniform, the water distribution pipelinesystem is prevented from being blocked, and the impact resistance is strong.

Description

technical field [0001] The invention relates to the technical field of sewage treatment technology, in particular to a variable-speed upflow hydrolysis acidification reactor. Background technique [0002] According to the difference in growth rate between methanogenic bacteria and hydrolytic acid-producing bacteria, the hydrolytic acidification process controls the anaerobic treatment in the first and second stages of anaerobic treatment with short reaction time, that is, under the action of a large number of hydrolytic bacteria and acidification bacteria, the insoluble organic matter It is the process of hydrolyzing into dissolved organic matter and transforming difficult biodegradable macromolecular substances into easily biodegradable small molecular substances, thereby improving the biodegradability of wastewater and laying a good foundation for subsequent treatment. Existing hydrolysis and acidification reactors are generally in the form of pools. Most of the water dist...
