Technical field
The utility model relates to advanced treatment of industrial waste water and recovery technology field, specifically a kind of reverse osmosis unit of handling trade effluent.
Background technology
At present, utilize advanced treatment that membrane technique carries out waste water, also accepted by people gradually as a maturation, advanced person, water technology efficiently.And with respect to other technologies, reverse osmosis technology has become a requisite gordian technique in many waste water reclaiming treatment technologies just because of having remarkable advantages at aspects such as removing solvability COD, heavy metal ion, colourity.Though reverse osmosis technology has the stable advantage of effluent characteristics.But when being three grades or level Four trade effluent when intaking, because condition of water quality is poor, reverse-osmosis membrane element very easily produces pollution, thereby the flux that causes water declines to a great extent, brings matting frequent, thereby causes reverse osmosis membrane to shorten work-ing life.Especially for some specific waste water quality, during as feed water by reverse osmosis, above-mentioned shortcoming is more outstanding as waste water such as plating, printing and dyeing, percolates.Simultaneously existing reverse osmosis system generally all adopts the two-part mounting means generally in order to improve the system recoveries rate, and promptly the dense water of first section reverse osmosis unit enters second section reverse osmosis unit and handles.In the reverse osmosis system of this structure, because the fluid concentration ratio of second section reverse osmosis unit increases, it is dirty especially easily stifled to form membrane element, cause system to be difficult for long-term stable operation, increase the replacing frequency of matting frequency and filtration consumptive material thus, thereby increased the advanced treatment running cost of trade effluent.
In addition, the trade effluent of different quality and the solid particulate in the waste water all can bring infringement to the reverse osmosis membrane of reverse osmosis unit.The solid sediment that produces in the concentrate recirculation treating processes of trade effluent also can further injure the pollution reverse osmosis membrane.
Summary of the invention
The purpose of this utility model is exactly at above-mentioned the deficiencies in the prior art, and a kind of reverse osmosis unit of further protecting the processing trade effluent of reverse osmosis membrane in the utilization ratio of effectively slowing down reverse osmosis membrane pollution, raising water is provided.
The technical solution adopted in the utility model is as follows:
A kind of reverse osmosis unit of handling trade effluent, it includes reverse osmosis unit, waste water is fed the high-pressure pump of described reverse osmosis unit, the receipts water tank that communicates with the water outlet of described reverse osmosis unit, the dense pond that communicates with the water port of described reverse osmosis unit, described dense pond is provided with the return line that is connected to the reverse osmosis unit water-in, wherein: the below of the reverse osmosis membrane in the described reverse osmosis unit is provided with the spray type aerating pipe, in the water inlet of described reverse osmosis unit the stainless steel grid is installed, on the return line between described dense pond and the described reverse osmosis unit water-in, is provided with the sandstone strainer.
Between the water port of reverse osmosis unit and water-in, also be provided with the return line of the dense water of backflow part.
At the water port of described reverse osmosis unit and the return line between the water-in, and be respectively equipped with flow control valve on the pipeline between the water port of reverse osmosis unit and the dense pond.Also can online monitor be installed, to guarantee the stably reaching standard of water quality treatment at effluent pipe mouth and dense pond water-in.
The utility model is installed the sandstone strainer at dense pond outlet, can effectively prolong the work-ing life of film.
The pipeline that the water port of described reverse osmosis unit connects water-in is provided with reflux pump.
The stainless steel grid of installing before the water-in of described reverse osmosis unit, material adopts 316L, guarantees that grid is not corroded, and can prolong its work-ing life.
The aeration tube connecting joint of described reverse osmosis membrane can adopt multi-functional reassembling type, and so both convenient for maintaining can effectively improve the utilization ratio of oxygen again.
The beneficial effects of the utility model have:
This device can prolong the work-ing life of reverse osmosis membrane, slowed down the pollution of reverse osmosis face effectively, can improve the processing efficiency of waste water, technical process is simple, can not only effectively prevent dense water side form surface organic contamination and various contamination precipitation, but also can avoid the generation of reverse osmosis membrane concentration polarization, it is stable also to have long-term operation simultaneously, characteristics such as convenience easy to maintenance.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of reverse osmosis unit of handling trade effluent of the present utility model, it includes high-pressure pump 3, reverse osmosis unit 6, adds water tank 8 and dense pond 4, the water outlet of high-pressure pump 3 connects the water-in of reverse osmosis unit 6, stainless steel grid 10 is installed in water inlet at reverse osmosis unit 6, and the water outlet of reverse osmosis unit 6 is connected to return water tank 8 by pipeline 7.
