Sewage purification and filtration device

Abstract

The invention discloses a sewage purification and filtration device. The sewage purification and filtration device comprises a precipitator (1) and a quick sand filter (6) filled with fine sand. The precipitator (1) is connected with a precipitator water inflow pipe (2), a precipitator water outflow pipe (3) and a precipitator blow-off pipe (5). A dirty sand cleaning and separating device and a filter water inflow pipe (7) are arranged in the quick sand filter (6) with the top end connected with a pure water outlet (14), and the tail end of the filter water inflow pipe (7) is connected with a water distributor (11) arranged in the quick sand filter (6). The dirty sand cleaning and separating device comprises a separator (8) and a sand lifting pipe (10) connected with a sand distributor (9). The separator (8) communicated with the sand lifting pipe (10) is connected with a sand discharging pipe (13) located inside the quick sand filter (6) and a dirt discharging pipe (12) penetrating out of the quick sand filter (6). The sewage purification and filtration device has the advantages of being low in maintenance cost, easy and convenient to operate, high in working efficiency and good in circulation water purification effect.

Description

technical field [0001] The invention relates to a novel sewage purification device in the field of sewage treatment, in particular to a sewage purification and filtering device. Background technique [0002] Landscape water pollution is mainly manifested as suspended solids and nutrients such as nitrogen and phosphorus exceeding the standard and interacting with each other. At the same time, the amount of pollutants in landscape water is large and the pollution speed is fast. Currently, the purification methods of landscape sewage on the market are mainly physical and chemical methods, including flocculation equipment, Sedimentation tanks, microfilters, sludge tanks, water pumps, booster pumps and other equipment. However, the existing sewage purification device needs to clean these purification equipment frequently during the sewage purification process, which increases the maintenance amount and maintenance cost, and the process is complicated and the operation is troubles...
