Abstract

The horizontal integrated three-phase internally circulating fluidized reactor has reactor box, guide plate and inclined precipitating plate to separate the rector box into three regions, lower filtering net, microporous aerator in the lower part of the upward flow region, water collector in the upper part of the mud-water separating region, and mud water valve in the lower part of the mud-water separating region. The bioreaction process inside the fluidized reactor includes: pumping organic waste water into the reactor and adding porous foamed sponge; introducing air into the microporous aerator for aeration; draining clear water via the water collector and depositing sludge to downward flow region; and draining rest sludge via the sludge exhausting valve.

Description

technical field [0001] The invention relates to a waste water treatment device and process, in particular to a horizontal integrated three-phase internal circulation fluidized reactor and a biological reaction process thereof. Background technique [0002] The research and application of biological fluidized bed wastewater treatment began in the early 1970s. In the 1980s, the biological fluidized bed process was used to treat industrial wastewater and began to be applied in engineering. The aerobic biological fluidized bed method can be divided into two-phase biological fluidized bed and three-phase biological fluidized bed according to the degree of mixing of gas, liquid and solid in the bed, as well as the difference in oxygen supply mode, bed structure, and film removal method. biological fluidized bed. Before the wastewater of two-phase biological fluidized bed enters the fluidized bed, it is pre-aerated with oxygen or air to make the wastewater...
