Problems solved by technology

[0002] The front-end pretreatment of the existing reverse osmosis treatment system generally uses ion exchange resin to remove the hardness in water. Since the ion exchange equipment needs to be regenerated, the resulting operating costs are extremely high. At the same time, the water often contains organic pollutants. In actual use, there are resin The problem of organic pollution

Abstract

The invention relates to a reverse osmosis treatment system with high recovery rate, comprising a coagulation device, a filter device and a reverse osmosis device, wherein one side of the coagulation device is provided with a pH value regulating device used for regulating the pH value of inflow water inside the coagulation device, and the other side of the coagulation device is connected with a coagulation water producing pot; the coagulation water producing pot is connected to one side of the filter device through a lift pump; a filter water producing pot is connected to the other side of the filter device; and the filter water producing pot is connected with the reverse osmosis device. The coagulation device and the filter device of the reverse osmosis treatment system with high recovery rate remove the insoluble salt which is easy to dissolve out on the surface of a reverse osmosis membrane, therefore the problem that crystallized mineral salt contained in the inflow water inside the reverse osmosis treatment system scales on the reverse osmosis membrane is effectively solved; meanwhile, the reverse osmosis device is operated under high pH, therefore the ionization degree of weakly ionized molecular substances is enhanced; and in addition, the invention has pure water recovery rate of more than 90 percent and also reduces the pollution of organic matters and microorganisms on the reverse osmosis membrane.

Description

technical field [0001] The invention relates to a high recovery rate reverse osmosis treatment system. Background technique [0002] The front-end pretreatment of the existing reverse osmosis treatment system generally uses ion exchange resin to remove hardness in water. Since the ion exchange equipment needs to be regenerated, the resulting operating costs are extremely high. At the same time, the water often contains organic pollutants. In actual use, there are resins The problem of organic pollution. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a high-recovery reverse osmosis treatment system, which is effective for water hardness, SiO 2 It has good removal effect, and can effectively prevent reverse osmosis membrane biofouling, and the system operation cost is low, and the investment is small. [0004] The technical scheme of the present invention to solve the above-mentioned technical problems is as fol...
