Method and device for optimizing a small sewage treatment plant by avoiding or reducing the output of sludge particles from the compressed air lifting system for clear water extraction

摘要

The invention relates to a device for optimizing a small wastewater treatment plant or small wastewater treatment plant by avoiding or reducing the discharge of sludge particles in wastewater treatment plants, small wastewater treatment plants and small sewage treatment plants, and other technical equipment by means of a simple device consisting of a compressed air lift (mammoth pump) for clear water discharge [24], to which a further compressed air lift (mammoth pump) [27, 39] is connected, which conveys the contained / deposited sludge particles [42] into the primary treatment [31] before the clear water discharge from the compressed air lift for the clear water withdrawal [24] or another container or Chamber promotes. Furthermore, the invention relates to a method for optimizing a small sewage treatment plants or small sewage treatment plant by avoiding or reducing the discharge of sludge particles, preferably in wastewater treatment plants, small sewage treatment plants and small sewage treatment plants, and other technical equipment characterized in that before the actual clear water withdrawal by a corresponding control command to the Compressed air lift for the clear water outlet [24] connected second compressed-air lift [27, 39] before the clear water outlet, the sludge particles contained in the air lift for the clear water outlet [24] promotes [32] in another treatment stage [31] or other container or chamber. The control command is characterized in that the activation of the second compressed air lift [27, 39] takes place in time before the actual clear water take-off.
