Domestic sewage purification and reutilization device

Abstract

The invention discloses a domestic sewage purification and reutilization device. The device comprises a barrel body, a micro-nano bubble generator, and a water distribution plate, a filter screen, a spiral filter pipe and a water storage tank which are sequentially communicated from top to bottom in the barrel body, the water diversion plate is in a semi-funnel shape, and a plurality of tooth-shaped protrusions are arranged on the edge of a lower water outlet of the water diversion plate. A plurality of filtering holes are formed in the filtering net and are in an inverted circular truncated cone shape; fiber membranes are attached to the two ends of the spiral filtering pipe respectively, the micro-nano bubble generator is spherical, a bubble discharging opening communicated with the interior of the barrel body is further formed in the side face of the barrel body, and a ventilating pipe is arranged on the micro-nano bubble generator. The device overcomes the problems in the prior artthat the utilization rate of domestic water is low, and a large amount of water resources are wasted and an existing purification device is not ideal in purification effect, calcium and magnesium ions in water are difficult to remove and a large number of trace elements beneficial to the human body are removed.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a domestic sewage purification and reuse device. Background technique [0002] The development of the domestic clean drinking water industry began in the 1980s. Household water purifiers have been used by 95% of households in developed countries in Europe and America, while the usage rate of households in China is less than 5%. However, my country's per capita water resources are only a quarter of the world's average level, while water consumption is huge. For example, the per capita water consumption in Beijing is 4 times the world average level, which provides a great market prospect for the production of water purifier products. Therefore, water purifiers still have a lot of room for development in China. [0003] In the prior art, the utilization rate of household domestic water is low, and it is generally used for one-time use, and the generated sewage is directl...

Problems solved by technology

[0005] In view of the above-mentioned technical problems, the purpose of the present invention is to overcome the low utilization rate of domestic domestic water in the prior art, which is generally used for one-time use, and the sewage produced is directly discharged, causing a large amount of waste of water resources; and the existing purification The purification effect of the device is not ideal, it is difficult to remove calcium and magnesium ions in the water, but it removes a large number of trace elements that are beneficial to the human body, so as to provide a method that can improve the utilization rate of domestic domestic water and form the recycling of domestic domestic water. To alleviate the water shortage situation in the country and the region, the domestic sewage purification and reuse device for the treatment, recycling, storage and use of domestic sewage
