Abstract

The invention provides an integrated non-gradient activated sludge sewage treatment device which includes a reactor shell body. The reactor shell body is provided with an accommodating space of which a top end is opened. A lifting cylinder is disposed in the accommodating space in the vertical direction and is provided with a channel of which an upper end and a lower end are opened. An air diffuser is arranged in the channel and is communicated with an external air pump through an aeration pipe. The reactor shell body is also provided with a water inlet, a sludge discharging outlet and a water outlet which are communicated with the accommodating space, wherein the water outlet is arranged above the water inlet and the sludge discharging outlet. The sewage treatment device can enhance a mass transfer effect and increase treatment efficiency, can enable a treatment range of sewage to be enlarged, can improve an anti-impact capability of an activated sludge system, can increase density of microorganism in a reaction zone, can increase a sewage treatment load, can save an occupied area and reduce cost, and meanwhile is convenient to operate and manage and is easy to control.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to an integrated non-gradient activated sludge sewage treatment device. Background technique [0002] Activated sludge method is an important sewage treatment method. For organic wastewater with good biochemical properties, activated sludge method has been widely used because of its advantages such as good treatment effect, low operating cost, and simple equipment. However, the traditional activated sludge plant is generally divided into two independent units, the aeration tank and the secondary sedimentation tank, so it has the characteristics of a large area, and the increasingly tight land use limits the use of this method to a certain extent; A sludge return pump needs to be installed between the aeration tank and the secondary sedimentation tank, which increases operating costs; the concentration of activated sludge in the aeration tank is low, so it cannot achieve a high treatm...
