Abstract
The invention discloses an SBR method intermittent sewage treatment device and a water purification method thereof. The SBR method intermittent sewage treatment device is composed of a buffer tank, a water delivery device, a reaction tank, stirring devices, a drainage device, an aeration device, a sludge discharge pipe, a support and a control system. The water delivery device delivers raw water to the upper portion of the left side of the reaction tank from the buffer tank, the aeration device continuously delivers air to the bottom of the reaction tank, and the stirring devices located in the middle in the reaction tank stir mixed liquor; when the water level reaches a critical value, the water delivery device stops delivering water, and the stirring devices and the aeration device also stop working after continuing operating for a period of time; after standing and setting of the mixed liquor are completed, the drainage device is started, and clean water is drained out of the reaction tank from a main drainage pipe on the upper portion of the right side of the reaction tank; after the clean water is completely drained, the drainage device is shut off, and the water delivery mode is started again. In this way, the process is conducted in an intermittent circulating mode.
