Problems solved by technology

[0005] At present, the decanters produced by most domestic decanter manufacturers have large power consumption and complicated control methods. Moreover, for industrial wastewater with strong corrosiveness, most of the decanter materials can no longer meet the requirements. Our company overcomes the above-mentioned defects in the development process, so that this low-power air-injection buoy type decanter has a wider application range and higher cost performance

Abstract

The invention discloses a low-powered pontoon type decanting method and a low-powered pontoon type decanting device, and relates to a device for decanting supernatant in a reaction tank by adopting a sequencing batch reactor activated sludge process in a sewage treatment plant. The device is arranged at a water outlet of a sewage tank and performs decanting by means of the buoyancy of a pontoon per se; the device mainly comprises a slag trap, a fixed pontoon, a gas injection pontoon, a weir, a water discharging branch pipe, a water discharging main pipe, a telescopic pipe, an electric control box, a liquid level switch 1, and a liquid level switch 2, a catch pin and the like; and by means of the buoyancy, the device complete decanting, and can effectively follow the change of the liquid level, has strong adaptability to the change of water quantity, and is a high-efficiency and energy-saving sewage treatment device.

Description

technical field [0001] The invention provides a drainage device for sewage treatment, which is mainly suitable for the drainage device in the process flow of the CASS, ICEAS, DAT-IAT method and the like of the SBR process. It belongs to the technical field of water treatment. Background technique [0002] The main pollutants of urban sewage are organic matter, so biochemical methods are mostly used at home and abroad. In the biochemical method, there are two major categories of activated sludge method and biological filter. The vast majority. There are many forms of activated sludge process, and the most widely used are three types: traditional activated sludge process, oxidation ditch, and SBR process, among which oxidation ditch and SBR process have become the preferred processes for small and medium-sized sewage treatment plants in China. [0003] The decanter is the key equipment in the SBR sewage treatment process, and it plays the role of discharging the supernatant...
