In figure：1st, comprehensive water collecting tank；2nd, sewage pump；3rd, integrated heavy metal adsorption reactor；4th, integrated desalination is anti-
Answer device；5th, reuse clean water tank；6th, sludge collecting tank；7th, filter press；8th, counter-flushing pipeline.
Embodiment
The content of the utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, the sewage disposal system of the utility model, including the i.e. comprehensive water collecting tank 1 of sewage storage tank, it is described comprehensive
The side of Heshui collecting tank 1 connects sewage pump 2 by pipeline, and the sewage pump 2 connects two groups of one being in series by pipeline
Change heavy metal adsorption reactor 3, the 3 connecting integration desalting reactor 4 of integration heavy metal adsorption reactor, the one
Change 4 piping of desalting reactor is connected back to be connected with clean water tank 5 and sludge collecting tank 6,6 side of sludge collecting tank by pipeline
Connecing filter press 7, the reuse clean water tank 5 connects each integrated heavy metal adsorption reactor 3 respectively by counter-flushing pipeline 8, and one
The bottom of body heavy metal adsorption reactor 3 connects sludge collecting tank 6 by pipeline.
By sewage after oil removal and natural subsidence, insert in comprehensive water collecting tank 1, received integrated water by sewage pump 2
Sewage in collection tank 1 squeezes into the processing that integrated heavy metal adsorption reactor 3 carries out heavy metal ion, which inhales
The inside of reaction enclosure device 3 is equipped with heavy metal absorbent cation exchange resin, passes through integrated heavy metal adsorption reactor string formation more than 3
Connection uses, can efficient absorption remove heavy metal, make sewage content of beary metal up to standard, and by connecting the backwash tube of clean water tank 5
The sludge that the backwash on road 8 can will be attached on heavy metal absorbent is expelled to sludge collecting tank 6 from reactor, it is achieved thereby that
The regeneration of adsorbent, also achieves the recycling of sludge, and sludge is recycled by filter press 7, then by setting integrated desalination
Reactor 4, can be greatly lowered the salt ionic concentration of sewage, so that sewage reaches the requirement of reuse.
Heavy metal adsorption process is equivalent to pretreatment in the utility model apparatus system, and desalination processes are equivalent to depth
Reason, i.e., first adsorb desalination again.And if first desalination is adsorbed again, due in long-time service, the higher heavy metal of concentration from
Son can block the such as NF membrane of equipment used in desalination, cause desalting reactor flux to decline, the lost of life, therefore this practicality
New to use first Adsorption heavy metal, content of beary metal is low in water outlet, enters back into desalter.
The sewage disposal system of the utility model is simple and practical in structure, and operational stability is strong, and maintenance workload is small.Pass through one
Body heavy metal adsorption reactor single group or it is multigroup be used in series, can efficient absorption remove heavy metal, make sewage content of beary metal
It is up to standard, then by setting the attached desalting reactor of integration, the salt ionic concentration of sewage can be greatly lowered, so that sewage reaches
The requirement of reuse.The utility model can be handled to obtain to the sewage containing heavy metal meets reuse requirement in industrial production
Water, is mainly used for technique cleaning, greening is kept a public place clean.
