Problems solved by technology

[0003] 1. The permeable membranes work in series, which occupies a relatively large area and requires high infrastructure investment costs;
[0004] 2. The osmotic membranes work in series, the pressure inside the osmotic membrane decreases step by step, but the concentration of sewage or seawater in the osmotic membrane increases step by step, so the water output of the osmotic membrane decreases step by step, so the osmotic separation efficiency is not high;
[0005] 3. The osmotic membranes work in series, and the water output of the osmotic membranes decreases gradually, that is, the utilization ratios of the osmotic membranes at all levels are different, so the service life of the osmotic membranes varies;
[0006] 4. The permeable membranes at all levels are embedded in the same protective tube. If any permeable membrane fails, it needs to be completely dismantled and overhauled, which is not conducive to monitoring and overhaul.

Abstract

The present invention discloses a reverse osmosis integration machine purification system, which comprises a prime mover, a separation and purification machine connected to the prime mover, and a permeation membrane unit or unit group connected to the separation and purification machine in parallel.

Description

technical field [0001] The invention relates to a water treatment system, in particular to a reverse osmosis integrated purification system. Background technique [0002] At present, almost all production processes such as industrial sewage and seawater desalination use osmotic membranes to work in series. The disadvantages are as follows: [0003] 1. The permeable membranes work in series, which occupies a relatively large area and requires high infrastructure investment costs; [0004] 2. The osmotic membranes work in series, the pressure inside the osmotic membrane decreases step by step, but the concentration of sewage or seawater in the osmotic membrane increases step by step, so the water output of the osmotic membrane decreases step by step, so the osmotic separation efficiency is not high; [0005] 3. The osmotic membranes work in series, and the water output of the osmotic membranes decreases gradually, that is, the utilization ratios of the osmotic membranes at al...
