MOVABLE LID TYPE SEWAGE SPRINKLER EQUIPPED WITH STREAM DISPERSER AND AUTOMATIC CLEANING MECHANISM

摘要

PPROBLEM TO BE SOLVED: To provide an improving technology of a water sprinkling filter bed apparatus subjecting organic sewage to an aerobic treatment wherein, when sprinkling sewage, clogging of the sprinkler by suspended matter in sewage is prevented, and sewage sprinkling is uniformized over the whole filter bed. PSOLUTION: This sprinkler is provided with a function of blowing off clogging matter by introducing compressed air from a compressor into a sewage flow-in pipe via a solenoid valve having a timer. A sprinkling member comprises a flange at an upper end of the sewage flow-in pipe and a movable lid type nozzle. The movable lid instantaneously floats up or returns along guide pins responding to injection or stop of compressed air. Sewage jetting out of the sprinkler impinges a water stream disperser and splashes to surroundings, covering all the wide filter bed to uniformly splash sewage, to enhance the function of a sprinkling filter.
