Abstract

The invention relates to the technical field of integrated sewage treatment devices, in particular to an integrated sewage treatment device based on an A3O + MBBR process, which is characterized in that an aerobic cavity and a precipitation cavity are respectively arranged at the upper part and the lower part of the middle part of a cylindrical box body, an anoxic cavity, an anaerobic cavity and a pre-denitration cavity are sequentially arranged outside the aerobic cavity, and a clear water cavity is arranged outside the precipitation cavity; a stirring rod rotationally sleeved at the center of a top cover is fixedly sleeved with the center of a disc, the bottom of a stirring shaft fixedly sleeved on the disc respectively corresponds to each cavity, a valve is arranged at the top end of a cylindrical shell fixedly sleeved at the center of the bottom surface of the aerobic cavity, a spiral conveyor is used for discharging sludge from the bottom of the precipitation cavity, and a spherical filler is filled in the aerobic cavity. The proportion of sewage injected into the pre-denitration cavity, the anaerobic cavity, the anoxic cavity and the aerobic cavity through a stirring shaft or a sewage straight pipe is 5: 2: 2: 1, a mechanism for returning sludge to the pre-denitration cavity and the anaerobic cavity is arranged in the precipitation cavity, and a mechanism for returning nitrification liquid to the anoxic cavity is arranged in the aerobic cavity; the sewage treatment efficiency is improved, and the occupied area is small.

Description

technical field [0001] The invention relates to the technical field of integrated sewage treatment devices, in particular to a 3 Integrated sewage treatment device of O+MBBR process. Background technique [0002] With the development of my country's economy and society, the crisis of water resources and the pollution of the water environment are intensifying, and the discharge of various sewage / wastewater has increased significantly, which seriously threatens the water environment and has become one of the hot spots in the field of environmental protection at home and abroad. The state has intensively issued a number of environmental protection and management related policies, and its focus has gradually shifted from industrial and urban pollution control to comprehensive environmental management in villages and towns. Village and town sewage treatment has become an environmental protection problem that needs to be solved urgently. Combined with the characteristics of scatt...
