Description

Technical Field

[0001] The utility model relates to the technical field of industrial sewage treatment, in particular to a reverse osmosis treatment device for a recycled water treatment system. Background Art

[0002] Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses pressure difference as a driving force to separate solvents from solutions. Because it is in the opposite direction of natural osmosis, it is called reverse osmosis. According to the different osmotic pressures of various materials, a reverse osmosis pressure greater than the osmotic pressure can be used, that is, reverse osmosis, to achieve the purpose of separation, extraction, purification and concentration.

[0003] A RO reverse osmosis filtration device for recycled water treatment disclosed in the Chinese utility model patent application disclosure CN207918552U achieves the effects of filtration and convenient cleaning through multi-layer filtration and sliding cover splicing. The number of pipeline upper shells is five, and the pipeline upper shells are parallel structures on the same horizontal plane. This structure achieves the effect of multi-layer filtration and the effect of water purification. The pipeline upper shell is an arc structure, and the bending angle of the pipeline upper shell is greater than 180°, and the inner diameter of the pipeline upper shell is smaller than the inner diameter of the pipeline lower shell. This structure is convenient for the pipeline upper shell to be combined with the pipeline lower shell to form a closed structure, and is convenient for maintenance. The filter screen is an inclined structure, and the bottom left side of the filter screen is seamlessly fitted with the top of the connecting plate. This structure is convenient for the first layer of filtration, filtering large granular impurities, and collecting and replacing them in the collection box. The air pump opening faces downward, and the air pump and the PP cotton swab are on the same straight line. This structure facilitates the action of the air pump and effectively accelerates the filtration process. However, the existing reverse osmosis treatment system not only has high operating costs, but also directly filters the liquid by the reverse osmosis membrane, which increases the burden of reverse osmosis membrane filtration, and is not convenient for removing impurities after filtration. The impurity removal effect is not ideal and needs to be developed urgently. Utility Model Content
