Abstract

The invention relates to a device for controlling an environmentally-friendly sewage aeration process and particularly to an energy-saving intermittent aeration control system which comprises an air blower which is connected by an air pipe and extends into an aeration pool. The control system is characterized in that the aeration pool is internally provided with three stages of aeration areas successively; each aeration area is internally provided with an efficient aeration nozzle and an aeration micro-stirring device; the efficient aeration nozzles are arranged on the air pipe; the aeration micro-stirring devices are arranged above the efficient aeration nozzles; and the air pipe is formed as an annular voltage-sharing spreading pipeline in each aeration area. According to the control system, the problems that the traditional aeration process has high requirements on the technology and experience of operation personnel, mistakes happens easily, a great deal of energy is consumed and the fault rate is high, are solved; the biochemical process efficiency is improved by controlling the dissolved oxygen in the aeration pool precisely and stably; the operation cost of sewage treatment plants is reduced greatly; and a tremendous electric charge is saved.

Description

technical field [0001] The invention relates to a device for controlling the aeration process of environmentally friendly sewage, in particular to an energy-saving intermittent aeration control system. Background technique [0002] At present, in the sewage dissolved oxygen treatment section of various domestic sewage treatment plants, the aeration tank process is generally used to increase the dissolved oxygen amount. At present, the manual adjustment method and the fixed value adjustment method are commonly used. [0003] Manually adjusting the aeration volume method is a method in which the operator adjusts the air volume of the blower every day or in a longer period of time according to experience and laboratory test data to make the aeration tank operate normally. Although this method can also make the aeration tank operate normally, and the effluent reaches the standard. However, this method cannot adapt to changes in the quality and quantity of influent water. In ord...
