Abstract

The utility model aims to provide a compound settling pond which occupies smaller area and is high in effective volume and use efficiency. Sewage enters into a water distributing area in a central pipe through a water inlet pipe, and then muddy water enters into a settling area through a clearance between a horn mouth and a reflecting plate so as to separate sludge from water, and clean water rises to a clarifying area and is drained after overflowing from an overflow weir to an overflow draining pipe. The sludge proportion is high, the sludge settles in a sludge area, the sludge is scraped into a sludge bucket by using a scraping plate of a central transmission sludge-scraping machine, and the sludge passes by a sludge draining pipe and is drained through a sludge draining pump and the sludge draining pipe. Compared with a conventional settling pond, the compound settling pond has the advantages that the compound settling pond has a square structure and is implemented in a modularized form; the compound settling pond can be combined with the other sewage pretreatment facilities and the subsequent sewage treatment facilities in the modularized form; the structure is compact; the use ratio of the occupied area is high; 20%-30% of occupied area is saved; and the volume use ratio of the settling pond and the settling effect are further increased.
