Background

Due to the rapid economic development in recent years, with further increasing environmental pollution, the sewage treatment technology adopted at present is mainly a suspended biological treatment technology based on an activated sludge process. Self-priming activated sludge process

Since 1914, the sewage treatment technology has been widely used, and is one of the most used sewage treatment technologies, and the technology principle is to treat the wastewater through the metabolism of flocculent sludge on organic matters, nitrogen and phosphorus.

In order to realize sustainable utilization and development of resources, strengthen recovery of resources such as nitrogen, phosphorus, nutrient substances and the like in wastewater, reduce emission of greenhouse gases when wastewater is treated, and the algae-bacteria symbiotic granular sludge process is widely focused; the process can reduce the energy consumption of aeration and the discharge of carbon dioxide and surplus sludge by the synergistic effect of algae bacteria, and is convenient for recycling.

At present, the research of the algae-bacteria symbiotic granular sludge is in a starting stage, so that a plurality of problems exist for the culture of the algae-bacteria granular sludge, a part of microalgae and sludge are in a suspension state, and the algae-bacteria granular sludge is difficult to settle and form; and a small amount of algae bacteria granular sludge exists in the upper water body, so that microalgae and flocculent sludge in the water body at the upper end of the reactor can be accelerated to be granulated by the aid of the cyclone separator, and the granular sludge with good granular performance and large granular density is further screened out.
