Water distribution system of IC (internal circulation) anaerobic reactor

Abstract

The invention discloses a water distribution system of an IC (internal circulation) anaerobic reactor. The water distribution system comprises a tank. An inner water distributor is arranged at the inner bottom of the tank, an outer water distributor is arranged on the peripheral side of the inner water distributor, an inner backflow water distribution device is arranged between the inner water distributor and the outer water distributor and is connected with an inner backflow pipe of a gas-liquid separator, and water inlet devices are connected with the inner water distributor and the outer water distributor. The water distribution system has the advantages that the structure of the IC anaerobic reactor can be simplified, the equipment investment can be reduced, water can be uniformly distributed, water distribution dead spaces and sludge accumulating, calcifying and hardening phenomena can be prevented, microorganisms can be in sufficient contact with organic matters, and treatment effects can be improved.

Description

technical field [0001] The invention relates to an IC anaerobic reactor, in particular to a water distribution system for an IC anaerobic reactor. Background technique [0002] The water distribution system is the core of the IC anaerobic reactor. The uniformity of the water distribution is directly related to the treatment effect of the IC anaerobic reactor, especially the water distribution of the IC anaerobic reactor with a larger tank diameter is difficult to ensure Uniformity of water is easy to produce dead zone of water distribution. As time goes by, sludge will accumulate, calcify and harden sludge, affect the full contact between organic matter and microorganisms, and finally affect the treatment effect. And in order to distribute water uniformly, most of the existing large-diameter IC reactors use 4 gas-liquid separators, and each gas-liquid separator is equipped with an internal return pipe, and the internal circulation return water passes through 4 internal retur...

[0002] The water distribution system is the core of the IC anaerobic reactor. The uniformity of the water distribution is directly related to the treatment effect of the IC anaerobic reactor, especially the water distribution of the IC anaerobic reactor with a larger tank diameter is difficult to ensure Uniformity of water is easy to produce dead zone of water distribution. As time goes on, sludge will accumulate, calcify and harden sludge, affect the full contact between organic matter and microorganisms, and finally affect the treatment effect

And in order to distribute water uniformly, most of the existing large-diameter IC reactors use 4 gas-liquid separators, and each gas-liquid separator is equipped with an internal return pipe, and the internal circulation return water passes through 4 internal return pipes. The reflux pipe returns to the bottom of the reactor, and increases the hydraulic load together with the raw water and the external circulation reflux water. The function is to make the organic matter fully contact with the microorganisms, so as to improve the degradation effect of the microorganisms on the organic matter. It is too complicated to be easy to use, and the investment in equipment is large
