Turntable filter

Abstract

The invention discloses a turntable filter which comprises a main framework, a core filtering system filtering net, a driving system, a backwash system and an automatic control system, wherein the main framework consists of a shell, a central water inlet pipe, a roller, a toothed gear, a rotating bearing, a central drum and a sealing piece; the driving system comprises a driving motor, a driving gear and a roller supporting wheel; and the backwash system comprises a reverse cleaning pump, a backwash sprayer, a flushing water pipe, a nozzle system, a sewage collecting groove and a blow-off line. Compared with the traditional process, the turntable filter has the advantages that the civil engineering such as a blowing room, a lifting pump room, a chlorination room, a clean-water reservoir and a settling pond are saved, the occupied area is small, and the occupied area of 10000-tonnage water is 15 square meters only and is only 1 / 7 to 1 / 6 of the area occupied by the traditional process, so that the maintenance and repair of the equipment are simple and convenient, the operating automation degree is quite high, special care is not required, and the labor intensity of workers and the maintenance cost are greatly reduced.

Description

technical field [0001] The invention relates to a rotary disc filter. Background technique [0002] With the increasing scarcity of water resources and the continuous increase of urban water demand, the recycling and reuse of advanced treated sewage has become an important part of water environmental protection projects. In 2002, the State promulgated the "Pollutant Discharge Standards for Urban Sewage Treatment Plants" (GB18918-2002), which stipulates that when the effluent of sewage treatment plants is introduced into rivers and lakes with small dilution capacity for urban landscape water and general reuse water, etc., a Grade A standard. In my country's three rivers and three lakes (such as Taihu Lake, Chaohu Lake, Dianchi Lake), the Liaohe River Basin of the Songhua River system, the important areas of the South-to-North Water Diversion, and the northern water-scarce areas (such as Hebei Province, Shanxi Province, Inner Mongolia Autonomous Region) and other areas with s...
