Combined-submerged pit water process and equipment

Abstract

The invention relates to a special process and a device for treating pit water by combining an ultrafiltration membrane component and a magnetic immersible pump. A treatment unit is formed by a special hollow fiber ultrafiltration membrane component and a water-permeable outer bushing; and power for filtering and conveying water is provided by the micro magnetic immersible pump fixed on the outer bushing of the membrane component. During working of the system, an eccentric wheel driven by the magnetic pump generates vibration on the membrane component so as to prevent pollution on the membrane and realize the function of washing the membrane. The treatment process can be used for deep treatment for the pit water, so that the treated pit water is in accordance with the national ruled water quality standard. The invention has the characteristics that: the treatment system is directly arranged in the pit water so as to prevent freezing of the equipment and the pipeline; the vibration caused by the eccentric wheel prevents pollution to the membrane component and realizes the function of washing the membrane; the treatment process is simple, the equipment is integrated, small in volume, light in weight, and low in manufacturing cost and running cost; and the process is a small-size household water purification process used by dispersed rural residents for treatment for the quality of the pit water.

Description

1. Technical field

[0001] The invention relates to a sewage treatment process in the technical field of water supply and drainage and water resource engineering and a series of equipment formed accordingly. According to the International Patent Classification (IPC), it belongs to C02F 1 / 00 2. Background technology

[0002] The arid region lacks a stable regular water source, so many scattered rural residents collect yard rainwater or haul water and store it in underground cisterns. Because the raw water collected and injected into the water cellar is polluted by the outside during the collection process, and it is stored in the water cellar for a long time, the water quality is poor, and it is far from meeting the relevant national drinking water quality standards. The processing of cellar water is very difficult, and there is still no suitable treatment process and corresponding equipment. The pollutants in the cellars are different, and the water quality cannot be determ...
