Multistage purifying and recovering device for household sewage and purifying method thereof

Abstract

The invention discloses a multistage purifying and recovering device for household sewage and a purifying method thereof and relates to the technical field of sewage treatment. The device comprises abottom plate. A precipitate purifying mechanism is fixedly connected to the left side of the upper surface of the bottom plate, an oil extraction mechanism is mounted above the precipitate purifying mechanism, a deslagging mechanism is mounted at the bottom end of the precipitate purifying mechanism, a filtering and purifying mechanism is mounted on the right side of the precipitate purifying mechanism, and a distilling mechanism is mounted on the right side of the filtering and purifying mechanism. According to the multistage purifying and recovering device for household sewage and the purifying method thereof, an oil stain layer of sewage can be extracted through a first water suction pump, and a threaded rod can be screwed out of a threaded pipe when bulky impurities in a precipitate box are cleaned, so that the impurities are discharged. Imported sewage can be filtered in multistage better. By heating the sewage through a heating stick, generated steam is imported into a recovery box to be collected through a folding pipe, so that the filtering using effect of the device is improved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a multi-stage purification and recovery device for domestic sewage and a purification method thereof. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements of a certain water body for drainage or reuse. Sewage treatment is widely used in construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment and catering And other fields, more and more have entered the daily life of ordinary people. The upstream suppliers of the sewage treatment industry are mainly manufacturers of sewage treatment equipment and suppliers of sewage treatment chemicals, all of which are fast-growing and in good demand. Industry, in daily life, will produce a lot of sewage. If the sewage is not reused, it will cause a lot of waste and loss of water resources. [0003] ...
