Fill same amount of activated carbon mixed liquor.
4th, hyperfiltration membrane assembly 11 need not be backwashed in the process of running, and to ensure effluent quality, each month right
Hyperfiltration membrane assembly carries out primary chemical cleaning.
The more traditional intermittent suction water-out manners of the present invention eliminate water outlet suction pump, rely primarily on film and enter water level and go out
There is gravity head liquid level difference between water level for driving force, realize continuous effluent, reduce part energy consumption.Powdered Activated Carbon
Return-flow system can make full use of the adsorption capacity of Powdered Activated Carbon.Combine Powdered Activated Carbon milipore filter GC-MS so that
System has the advantages that producing water water quality is excellent, the low, floor space of water consume energy processed is small, equipment investment, it is adaptable to scattered rural water supply
Treatment.
In the present embodiment, the specification of membrane cisterna 10 is 13cm*9cm*35cm, and volume is about 4L, it is easy to dispose.Intake pump 3 is held
Continue and supply raw water to membrane cisterna 10, the constant liquid level in membrane cisterna 10 is controlled by overflow pipe 13.Hyperfiltration membrane assembly 11 uses immersion
Operation, places 4 hyperfiltration membrane assemblies 11 altogether in membrane cisterna 10, the water inlet area of each milipore filter membrane module 11 is 336cm2, total face
Product is 1344cm2.The discrepancy in elevation between the water inlet liquid level and water outlet liquid level of system is that 1m, i.e. transmembrane pressure are 0.1bar, by adjusting
The different liquid level difference of section can obtain different water flows.Gravity type ultrafiltration membrane process need not recoil to membrane module
Wash.The dosage of Powdered Activated Carbon is 100mg/L in membrane reactor, and the active carbon amounts of half is changed every 12h.Film low aeration rate
It is 0.25m3/h。
Initial operating stage, membrane flux (transmission rates) is constantly in downward trend.After operation 20h, membrane flux is finally stablized
At 50L/ (m2hbar).Water treatment effect aspect, gravity type ultrafiltration membrance filter and powder electroless plating combination technique
