Pneumatic honeycomb ceramic biological rotating disc

Abstract

The invention discloses a pneumatic honeycomb ceramic biological rotating disc. The biological rotating disc comprises porous honeycomb filling material (1), air grooves (2), a disc framework (3), a rotating shaft (4) and net covers (5), wherein the disc framework (3) is cylindrical; the net covers (5) are arranged on two sides of the disc framework (3); the rotating shaft (4) is arranged in the center of the disc framework (3); the air grooves (2) are formed in the outer circumference of the disc framework (3); the porous honeycomb filling material (1) is located in the net covers (5) on the two sides of the disc framework (3); the particle diameter of the porous honeycomb filling material (1) is 60-120 mm; the porous honeycomb filling material (1) is ceramic and comprises an inner-layer honeycomb body and an outer-layer honeycomb body, the outer-layer honeycomb body is a hollow honeycomb body shaped like a fishing net, the inner-layer honeycomb body is a transformation honeycomb body, the inner-layer honeycomb body and the outer-layer honeycomb body are strung and hung, so that the filling material (1) is large in specific surface area, easy for biological membranes to stick to, high in biomass and high in treatment efficiency.

Description

technical field [0001] The invention relates to sewage treatment technology in the discipline of environmental engineering, is an advanced technology applied to the treatment of small and medium-sized domestic sewage and industrial waste water, and specifically relates to the field of biofilm technology. Background technique [0002] With the acceleration of urbanization and the continuous growth of urban industries, industrial sewage has become an important source of pollution to the water environment, increasing the eutrophication of lakes in my country and the deterioration of the water environment, directly threatening the safety of drinking water for the people and the urban economy. of sustainable development. At present, biological treatment is the main method of sewage treatment, which can be divided into activated sludge method and biofilm method. Due to the mature technology and reliable equipment, the activated sludge method is widely used in large-scale sewage tr...
