Algin produces the partially recycled utilization of waste water, using water wisely, protects environment, and present system is simple to operate, and processing cost is low,
Economical and practical.
This utility model is to be achieved through the following technical solutions:
A kind of algin production waste water recycling system, it include sedimentation unit, flocculation unit, filter press unit,
The dense water store tank of Microfiltration Unit, ultra filtration unit, reverse osmosis units and ultrafiltration；
Wherein sedimentation unit, flocculation unit, filter press unit, Microfiltration Unit, ultra filtration unit, reverse osmosis units lead to successively
Cross water pipe to be connected；Ultrafiltration dope holding vessel unit is connected with ultra filtration unit and flocculation unit；
First algin production waste water is collected in sedimentation unit, settles through inclined plate sedimentation pond, removes partial suspended
Thing and impurity；After the waste water of sedimentation, enter flocculation unit, at flocculation unit, add flocculant polyacrylamide, after mixing,
Carry out flocculating sedimentation；Waste water after flocculating sedimentation enters filter press unit, uses filter press to carry out filter pressing；Filter pressing
Water outlet enters Microfiltration Unit, carries out microfiltration process；Microfiltration water enters ultra filtration unit, carries out hyperfiltration treatment, and the dense water of ultrafiltration is in ultrafiltration
Dense water pot storage element stores, and subsequently into flocculation unit, processes further；Ultrafiltration water enters reverse osmosis units, carries out
