Abstract
The utility model discloses a device capable of reducing reverse osmosis or nano-filtration concentrate salt of landfill leachate. A concentrate outlet of a reverse osmosis or nano-filtration device is connected with an inlet of a lime reaction tank, the outlet of the lime reaction tank is connected with the inlet of a flocculating agent reaction tank, and the outlet of the flocculating agent reaction tank is connected with a sludge precipitation tank and a clear liquid tank respectively. By adopting the device, the salt in the concentrate solution can be effectively reduced, the harm to the environment is furthest reduced, and investment cost and the running cost are low.
Description
Technical field:
The utility model belongs to a kind of water treating equipment, a kind of especially device that reduces percolate reverse osmosis or nanofiltration concentrated solution salinity.
Background technology:
High-concentration sewage take percolate as representative generally exists Pollutant levels height, complicated component, water yield less, the relevant higher characteristics of effluent quality standard-required.Owing to contain certain density hardly degraded organic substance in the sewage, adopt biochemical processing process its processing can not be reached relevant discharging water quality standard fully, so the membrane filtration techniques such as reverse osmosis or nanofiltration become end-filtration and process to guarantee that effluent quality is up to standard.
But, no matter be nanofiltration or reverse osmosis, necessarily have concentrated solution and produce, mainly be the pollutent that film is retained down in the concentrated solution.Reverse osmosis membrane can effectively dam and comprise the small-molecule substance of monovalent salt, so reverse osmosis water outlet can reach very high emission standard, but its concentrated solution salt content is very high.Nanofiltration membrane has the selection perviousness, and monovalent salt (comprising ammonium salt and nitrate, nitrite) all can't be dammed by nanofiltration membrane, so the too late reverse osmosis membrane of nanofiltration water outlet protection up to standard, but saltiness is lower in its concentrated solution.Therefore, the high concentrated solution of these saltness becomes a difficult problem in all leachate treatments.
Summary of the invention:
The purpose of this utility model just is to overcome above-mentioned the deficiencies in the prior art, and provide a kind of device that reduces percolate reverse osmosis or nanofiltration concentrated solution salinity, this device can reduce the salinity in the concentrated solution effectively, at utmost reduce the harm to environment, and cost of investment and running cost are cheap.
As above design, the technical solution of the utility model is: a kind of device that reduces percolate reverse osmosis or nanofiltration concentrated solution salinity, comprise reverse osmosis or nanofiltration device, it is characterized in that: the concentrated solution outlet of reverse osmosis or nanofiltration device is connected with the import in lime reaction pond, the outlet in lime reaction pond is connected with the import of flocculation agent reaction tank, and the outlet of flocculation agent reaction tank is connected with clean solution tank with the precipitating sludge pond respectively.
The utlity model has following advantage and positively effect:
1, concentrated solution is in the lime reaction pond, double oxygen bacterium effect by lime is carried out open chain to the macromole organic pollutant of difficult degradation in the concentrated solution, be degraded into the small molecules type organic, improve the biodegradability of waste water, and then after passing into the interior hybrid reaction processing of flocculation agent reaction tank, can reduce the salinity in the concentrated solution, and farthest reduce the pollution to environment.
But 2 assurance devices carry out stabilization treatment to concentrated solution.
3, simple in structure, easy to use, cost of investment and running cost are cheap.
Description of drawings:
Fig. 1 is synoptic diagram of the present utility model.
Embodiment:
As shown in the figure: a kind of device that reduces percolate reverse osmosis or nanofiltration concentrated solution salinity, the concentrated solution outlet of reverse osmosis or nanofiltration device is connected with the import in lime reaction pond, the outlet in lime reaction pond is connected with the import of flocculation agent reaction tank, and the outlet of flocculation agent reaction tank is connected with clean solution tank with the precipitating sludge pond respectively.
Innovative point of the present utility model is to pass in the lime reaction pond in the concentrated solution of reverse osmosis or nanofiltration processing generation and degrades, pass into again and carry out the hybrid reaction processing in the flocculation agent reaction tank, with the mud mixture precipitation process, discharge precipitating sludge, reduce the concentrated solution salinity.
