Technical Field

The utility model relates to the technical field of decanter equipment, in particular to a siphon type decanter.

Background

The main pollutant of urban sewage is organic matter, so that at present, biochemical method is mostly adopted at home and abroad. In the biochemical method, there are two major categories, namely an activated sludge method and a biological filter, the biological filter has low treatment efficiency and poor sanitary condition, and only few biological filter urban sewage treatment plants in China exist, but the activated sludge method occupies the vast majority. The activated sludge process has a wide variety of forms, and there are three main types of processes that are most widely used: the traditional activated sludge method, oxidation ditch and SBR process are the first choice of the domestic small and medium-sized sewage treatment plants. The decanter is the most commonly used key equipment in the sewage treatment processes such as a CASS method, an SBR method, a CEAS method and the like.

The decanter is also called a decanter and is one of the most critical mechanical devices in the SBR process. Can be divided into a siphon type decanter, a rotary decanter, a self-floating type decanter and a mechanical decanter, and is widely applied in China (belongs to one of the mechanical decanters). The decanter is a device for periodically discharging clarified water used in the SBR process, and has the function of decanting the clarified water from the surface of a static pool without stirring sediment, so as to ensure the quality of effluent. Because the SBR process adopts intermittent reaction, water inflow, reaction, precipitation and drainage are completed in the same tank, a secondary precipitation tank and sludge reflux equipment are not needed, and the SBR process has the advantages of small occupied area, small investment, high efficiency, good effluent quality and the like; meanwhile, a plurality of SBR tanks are connected, the continuity (continuous water inlet) of the traditional sludge process can be realized, the intermittence of the typical SBR process is realized, and the method is suitable for the requirements of large water quality, water quantity and change, so that the method is widely applied at home and abroad.

In the prior art, the decanter is usually directly placed in sewage, and is not regulated by a regulating device, so that the starting of drainage is inconvenient to control, and when the water surface descends, the decanter is inconvenient to move downwards, so that the operation is inconvenient.
