【摘要】 水力藻类床是针对城市污水的深度处理系统,由生长水生附着生物的水渠、脉冲布水装置、旋转筛网、滤池、紫外消毒单元等组成,藻类由收割机定期收割。细菌、藻类和附着水生物在水渠中自然组合。藻类在水力藻类床中对磷的去除起主导作用。一年中优势的藻类种群为藻青菌和硅藻属,丝状藻类能够通过过滤、吸附、同化(包括过度摄取)和沉淀作用去除污水中的磷。更多还原

【Abstract】 Patterson algae turf scrubber is an advanced wastewater treatment technology for municipal wastewater. It consists of a water ditch on the surface of which the periphyton grows, a vibrator which produces the pulse of water flow rotary screen strainer, sand filters and UV disinfection unit. Algae are harvested by harvester regularly. Bacteria, algae and periphyton (filamentous algae) are intergrowth in the water ditch naturally, in which algae play the leading role for phosphorus removal. For much of the year, the predominant algae species are cyanobacteria and diatoms, filamentous algae may remove phosphorus from wastewater by either filtration, adsorption, assimilation(including luxury uptake) or precipitation.更多还原
