Problems solved by technology

[0003] The general flushing method of the ultrafiltration membrane filter element is to open the water inlet and the flushing port at the same time, and the water in the water inlet will wash away the dirty water in the filter bottle. It is difficult to clean out the dirt by flushing alone, which will shorten the service life of the filter element and prevent the filter element from being better utilized

Abstract

The invention discloses a water purifier for treating domestic wastewater by adopting an external pressure type ultrafiltration filter element. A structure of the water purifier comprises a polypropylene melt blown water purifying mechanism, a granular activated carbon water purifying mechanism, a compressed activated carbon water purifying mechanism, a machine body, an ultrafiltration membrane water purifying mechanism and a post activated carbon water purifying mechanism. Compared with the prior art, the water purifier provided by the invention has the following beneficial effects: a No.1 shaking group, the ultrafiltration membrane filter element, an outer shell, a No.2 shaking group, a connecting plate, a micro motor and an engaged wheel are combined, so that when the filter element isflushed, the filter element can be shook in a reciprocating non-intermittent manner; when the shaking direction is opposite to a flushing water flow direction, impact force of water on dirt can be increased, and the dirt is conveniently separated from membrane fibers; and when the shaking direction is the same as the flushing water flow direction, the dirt can be washed out along a water flow, prolonging of the service life of the filter element is facilitated, the filter element can be maximized, the filter element does not need to be replaced in a short time, and the water purification costsare reduced.

Description

technical field [0001] The invention relates to the technical field of domestic wastewater treatment, in particular to a water purifier for domestic wastewater treatment using an external pressure ultrafiltration filter element. Background technique [0002] The technical core of the water purifier is the filter membrane in the filter element device. At present, the main technology comes from ultrafiltration membrane and RO reverse osmosis membrane. As far as the external pressure ultrafiltration membrane is concerned, its flow rate is positive to the amount of dirt on the outer surface of the membrane wire. For example, when the flow rate of the ultrafiltration membrane element is small, it is necessary to flush the ultrafiltration element. [0003] The general flushing method of the ultrafiltration membrane filter element is to open the water inlet and the flushing port at the same time, and the water in the water inlet will wash away the dirty water in the filter bottle. ...
