Description

Sewage lifting device and biochemical reactor

Technical Field

Background

Currently, biochemical methods are the most commonly accepted relatively economical main treatment methods in sewage treatment plants (stations) of various sizes, and are commonly known as AO, A2O processes and improved processes thereof. The A2O process is often provided with a pool body area with three different characteristics and functions of anaerobic, anoxic and aerobic. Wherein the anaerobic zone is a non-oxygenated zone of the biological reaction tank and no nitrate or nitrite exists, and the phosphorus accumulating microorganisms perform processes of absorbing organic matters and releasing phosphorus in the anaerobic zone; the anoxic zone is a non-oxygenated zone of the biological reaction tank and has a zone where nitrate or nitrite exists, and denitrification reaction can be carried out when sufficient organic matters are obtained; the aerobic zone is the oxygenation zone of the biochemical reaction tank, and the oxygen content in water is usually up to more than 1.0mg/L through aeration, and microorganisms in the zone can carry out degradation and nitration reactions of organic matters. The three areas are matched with each other, so that the sewage is subjected to denitrification and dephosphorization, thereby reducing BOD, COD and the like.

In the related art, in order to ensure the removal rate of total nitrogen, a relatively high nitrifying liquid reflux amount is generally required, nitrifying liquid at the tail end of an aerobic zone is refluxed to an anoxic zone for denitrification, and then sewage is required to be lifted to promote the directional flow of mixed liquid in a sewage tank. However, when the sewage is lifted by the lifting device, the size of the lifting channel in the lifting device is fixed, and the lifting efficiency of the sewage cannot be improved by changing the size of the channel according to the actual condition of the sewage.
