Abstract
The invention discloses a reverse osmosis apparatus for industrial wastewater treatment, comprising a reverse osmosis apparatus (6). Wastewater enters a water inlet of the reverse osmosis apparatus (6) through a high pressure pump (3). The water outlet of the reverse osmosis apparatus (6) is connected with a recycling water tank (8) through a pipeline. The water discharge opening of the reverse osmosis apparatus (6) is connected respectively with a water outlet pipe of the high pressure pump (3) and a concentrated water pool (4). The concentrated water pool (4) is further provided with a reflow pipe (9) connected with the water inlet of the reverse osmosis apparatus (6). The invention can effectively reduce pollution on the surface of the reverse osmosis membrane and improves the utilization rate of water. The invention does not only simplify the process flow, increase the water supply flow and speed, but also enhancing the washing capacity of water flow on the membrane to dirties, thereby effectively preventing influence of sediment of various impurities on the reverse osmosis membrane and prolonging the service life of the membrane.
Description
Technical field
The present invention relates to advanced treatment of industrial waste water and recovery technology field, specifically a kind of reverse osmosis equipment that is used for Industrial Wastewater Treatment.
Background technology
Utilize advanced treatment that membrane technique carries out waste water as when last ripe, advanced, water technology efficiently, accepted by people gradually.And with respect to other technologies, reverse osmosis technology has become one of gordian technique in the utilization of wastewater resource technology owing to have remarkable advantages at aspects such as removing solvability such as COD, heavy metal ion, colourity.Though reverse osmosis technology has the high advantage of effluent characteristics, when intaking, because condition of water quality is poor to tertiary grade industrial waste water; Reverse-osmosis membrane element very easily produces pollution, thereby causes that water flux descends, and brings matting frequent; Cause the reverse osmosis membrane lost of life; Especially for the complicated water quality of some compositions, for example when tertiary treatment waste water such as plating, printing and dyeing, percolate during as feed water by reverse osmosis, then above-mentioned shortcoming is more outstanding.Simultaneously, existing reverse osmosis system for improving the system recoveries rate, generally all adopts two-part to handle mounting means when manufacturing and designing, and promptly the dense water of first section reverse osmosis unit, gets into second section reverse osmosis unit after treatment again and handles.Adopt the reverse osmosis system of this project organization; Because the fluid concentration ratio at second section reverse osmosis unit increases; The dirt that forms membrane element easily is stifled; Cause system to be difficult for long-term stable operation, not only increased the replacing frequency of matting frequency and filtration consumptive material thus, but also increased the running cost of advanced treatment.
Summary of the invention
The object of the invention is exactly the deficiency to above-mentioned prior art, provides a kind of and can effectively slow down the reverse osmosis membrane surface contamination, can improve the reverse osmosis equipment of a kind of Industrial Wastewater Treatment of water use efficiency simultaneously.
The technical scheme that the present invention adopts is following:
A kind of reverse osmosis equipment that is used for Industrial Wastewater Treatment; It includes reverse osmosis unit; Waste water enters into the water-in of reverse osmosis unit through HPP; To return water tank, the water port that it is characterized in that reverse osmosis unit is connected respectively to the rising pipe and the dense pond of above-mentioned HPP through pipeline to the water outlet of reverse osmosis unit, also is provided with the return line that is connected to the reverse osmosis equipment water-in on the dense pond through pipe connection.
Water port on the said reverse osmosis unit is connected to the rising pipe of above-mentioned HPP and the pipeline in dense pond is provided with regulating valve.
The pipeline that water port on the said reverse osmosis unit is connected to above-mentioned HPP rising pipe is provided with reflux pump.
Beneficial effect of the present invention has:
Can effectively slow down the pollution on reverse osmosis membrane surface, thereby improve the utilization ratio of water.Not only technical process is simple; Increased water supply flow and flow velocity, but also strengthened the scouring capability of film surface current, can effectively prevent the influence that various contamination precipitations bring reverse osmosis membrane dirt; Prolong the work-ing life of film, improved the stability of operation.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described:
As shown in Figure 1; The present invention mainly includes HPP 3, reflux pump 5, reverse osmosis unit 6, adds water tank 8 and dense pond 4; The water outlet of employing HPP 3 is connected to the water-in of reverse osmosis unit 6; The water outlet of reverse osmosis unit 6 is through pipe connection to return water tank 8, and the water port of said reverse osmosis unit 6 is connected respectively to the rising pipe and the dense pond 4 of HPP 3 through pipeline.And be connected in the water port of reverse osmosis unit 6 on the pipeline in rising pipe and dense pond 4 of HPP 3 and be provided with regulating valve 2, be mainly used in the adjusting of the backflow water yield.Simultaneously, also can be as required on the water port of reverse osmosis unit 6 is connected to the rising pipe pipeline of HPP 3, be provided with reflux pump 5,, improve the utilization ratio of water to add the speed of strong inverse flow.Also be provided with the return line 9 that is connected to reverse osmosis equipment 6 water-ins on the dense pond 4, handle once more so that the water in the dense pond 4 is refluxed.
When the present invention works, have waste water 1 to arrive the HPP 3 from water inlet pipe earlier, enter into reverse osmosis unit 6 from HPP 3 through the HPP rising pipe again, after reverse-osmosis treated, water purification enters into return water tank 8 from water producing pipe 7, is used for recycling.Simultaneously the dense water of part after reverse-osmosis treated is then got back to the dense pond 4 from the water port of reverse osmosis unit 6, and in this process, still some dense water enters into reverse osmosis unit 6 through backflow and carries out secondary treatment.
The undeclared part of other that the present invention relates to is identical with prior art.
