Abstract

The invention relates to integrated sewage treatment equipment and method. The equipment comprises an inner barrel, a middle barrel and an outer barrel which are sequentially arranged from inside to outside, wherein an anaerobic zone is arranged inside the inner barrel; an anoxic zone is arranged between the middle barrel and the inner barrel; an aerobic zone is arranged between the outer barrel and the middle barrel; a through hole is formed in the side wall of the inner barrel; the through hole is used for introducing sewage in the anaerobic zone into the anoxic zone; a circulating hole is formed in the side wall of the middle barrel for realizing communication between the anaerobic zone and the aerobic zone; guide plates with adjustable deflection directions are separately arranged at the two sides of the circulating hole, and are used for controlling a circulating direction and circulating amount of sewage; the aerobic zone is provided with an aerator; and a film assembly is further arranged in the aerobic zone and is used for realizing solid-liquid separation in the aerobic zone. The equipment disclosed by the invention can conveniently and effectively treat sewage. Dischargedwater can reach primary standards of Town Sewage Treatment Plant Pollutant Discharge Standards (GB19818-2002). The invention further discloses a method for treating sewage by utilizing the equipment.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an integrated sewage treatment equipment and method. Background technique [0002] At present, centralized treatment is generally adopted for domestic sewage. The centralized treatment uses the sewage pipe network to collect the domestic sewage generated by residents, and uniformly discharges it into centralized domestic sewage treatment facilities for secondary biochemical treatment. This processing method is often used in cities or market towns, where many residents live together, but for the vast countryside, especially the rural residents in the southern hilly areas, due to the limitation of the terrain of the place of residence, they basically live scattered on the hillside or on the hillside. For the domestic sewage treatment of these residents in the river valley, if the centralized treatment method is adopted, the cost of the sewage collection pipe network will b...
