Abstract
The invention belongs to technical field of sewage, specifically, the present invention relates to a kind of blowdown water handling reclamation system, including pretreatment system and film deep desalting system；The pretreatment system includes conditioning tank, clarifying basin, ultrafiltration apparatus and sludge treatment equipment；The film deep desalting system includes reverse osmosis treatment device；The conditioning tank is for receiving and adjusting sewerage；The clarifying basin is connected to the conditioning tank, the sludge treatment equipment, the ultrafiltration apparatus respectively；The ultrafiltration apparatus is connected to the reverse osmosis treatment device；The reverse osmosis treatment device is used for advanced treating sewerage, and desalination makes up to and produces water reuse standard, reduces concentrated water drainage.The present invention can maximize the discharge amount for reducing sewage, sludge, realize the cascade utilization of resource, have the characteristics that short process, simple process, monomer process mature and reliable, strong shock resistance, stable, good sewage processing effect, economical and environmentally friendly benefit can be generated greatly.
Description
Technical field
The invention belongs to technical field of sewage, specifically, the present invention relates to a kind of blowdown water handling reclamation systems.
Background technique
Power plant cycle sewerage has the characteristics that water is big, hardness is high, suspended matter is high.Main water consumption portion as power plant
Point, sewerage reuse is to alleviate one of water resources crisis, the effective way for protecting water environment.If effective technique can be passed through
Technology carries out advanced treating to circulating sewage, can not only improve sewerage concentration rate, reduce blowdown flow rate, additionally it is possible to will locate
Moisturizing of the production water as boiler feed water system and recirculating cooling water system after reason, thus greatly reduce the water consumption of power plant,
With far-reaching economy and environmental benefit.
Currently, the processing of sewerage, there are many kinds of method, most of processing method generally adds medicament circulation, electrification
Processing, multistage coagulating sedimentation and multistage concentration, resin adsorption processing.Since soluble solid content is high in sewage, and
Different causes sewerage water quality difference big with water water source, and fouling components are different, thus generated when dosing coagulating sedimentation
The parameters such as sludge type, granular size are different, cause technique chain length, anti-fluctuation is poor, and coagulating sedimentation is ineffective, hardness (water
Contained in calcium, magnesium, iron, aluminium, zinc plasma) removal rate is low, subsequent concentration stage low efficiency, the problems such as service life is short, entire work
Process system fluctuation of service, or even it is difficult to longtime running.Thus finding that a kind for the treatment of process is relatively easy, monomer process is mature can
It leans on, the combined system of function admirable becomes circulating sewage and handles urgent problem to be solved.
Summary of the invention
To solve the above-mentioned problems, the present invention provides a kind of blowdown water handling reclamation system, its technical solution is as follows:
A kind of blowdown water handling reclamation system comprising: pretreatment system and film deep desalting system；The pretreatment system packet
