Abstract

The invention discloses an underground medical sewage treatment device, which is characterized in that a water distribution area, an anoxic area and an aerobic area are arranged in the tank body, so that the sewage enters the anoxic area from the bottom of the tank body, and then rises to the aerobic area , The sewage after aerobic treatment is discharged up to standard through mud-water separation and disinfection. Compared with the prior art, the present invention has simple structure and convenient operation, effectively solves the problem that the upper part of the water cannot be treated with anoxic first and then aerobic treatment, and has low operating cost, floor space and convenient maintenance, and is especially suitable for small medical institutions sewage treatment.

Description

technical field [0001] The invention relates to the technical field of medical sewage treatment equipment, in particular to an underground medical sewage treatment device. Background technique [0002] At present, government functional departments have higher and higher requirements for the discharge water quality of small medical sewage. The original one-level intensive treatment + disinfection method is difficult to meet the current sewage discharge requirements, and small medical institutions are in short supply of land and have no professional management personnel. AO treatment is one of the typical methods of domestic sewage treatment, and the sewage of medical institutions is largely a kind of domestic sewage. However, due to the particularity of medical institutions, there are often a large number of pathogenic bacteria in the drainage, which needs to be disinfected before treatment. emission. The existing AO technology divides each functional area in the form of poo...
