The external tubular type ultra-filtration equipment of described percolate is taken over the tubular ultra-filtration membrane assembly that is together in series with symphysis and is installed on the bracing frame, and electrical control cabinet is housed on frame, controls the switching of each valve on the pipeline by electrical control cabinet.
The utility model positively effect is:
1, because the high efficiency separation effect of ultra-filtration membrane, separating effect is much better than traditional settling tank, treat effluent is extremely limpid, suspended substance and turbidity approach zero, bacterium and virus are significantly removed, effluent quality is better than miscellaneous domestic water quality standard, can be directly drinks municipal miscellaneous water and carries out reuse as non-.
2, simultaneously, membrane sepn also makes microorganism be dammed in bio-reactor fully, make and to keep higher microorganism concn in the system, not only improved reaction unit the whole removing of pollutent has been removed efficient, guaranteed good effluent quality, reactor has excellent adaptability to the various variations of influent load (water quality and the water yield) simultaneously, and anti impulsion load can be stablized acquisition fine effluent quality.
3, excess sludge production is few, and this device can move under high volumetric loading, low sludge loading, and excess sludge production is low, has reduced the sludge treatment expense.
4, floor space is little, occasion is not set limits, and this device flow process is simple, compact construction, small accommodation area, the place is not set limits, and is suitable for any occasion, can make ground type, semi-underground type and underground type.
5, can remove ammonia nitrogen and hardly degraded organic substance.
6, convenient operation and management is easy to realize automatic control; 7, be easy to transform from traditional technology.
