It is possible to cause sludge settling, influences operational effect.Especially under the thin operating mode of influent quality, surface aerating machine must be reduced for energy-conservation
Rotating speed, but can drastically weaken reduction stirring capacity, cause to precipitate overweight, sludge alluvial.
(3) in BAF, to avoid blocking follow-up biological aerated filter into the suspended particulate in water, one
As be both needed to use dosing to strengthen the effect that preliminary sedimentation tank removes suspended solid, so as to which reagent cost can be increased.It is to reach filter simultaneously
Pond water distribution intensity and uniformity requirements, generally require one-level elevator pump and go out flowing water head with higher, increase to a certain extent
Inlet water lifting pumps energy consumption；
(4) stabilization pond treatment technology due to hydraulic load it is low, cause its floor space larger；Climate change is to stabilization pond
Treatment effect has a great influence；If design or operational management are improper, secondary pollution can be caused；It is also easy to produce stink and grows mosquitos and flies；
Sludge is not easy to discharge and handles utilization, and in many places, stabilization pond becomes mosquitos and flies and grow source into sump.
(5) artificial wetland treatment load is relatively low, floor space is big；Wetland plant is exposed easily to be influenceed processing effect by pest and disease damage
Fruit；Biology and waterpower polytropy increase inaccurate to its treatment mechanism, designed breeding, and then water outlet is not reached design
It is required that or be unable to qualified discharge, discarded wetland of lying waste is found everywhere in rural area, and somebody's work wetland is on the contrary into pollution sources.
