Abstract

The invention relates to the technical field of sewage treatment and provides a facultative microalgae photobioreactor sewage purification system. The facultative microalgae photobioreactor sewage purification system comprises a bioreactor, a vertical light distribution device, an aeration device, an algae residue collector and facultative microalgae. The system comprises the vertical light distribution device and the aeration device, during applying, the interior of the system can be supplemented with air and a light source, thus the optimal growth conditions are provided for the facultativemicroalgae, the facultative microalgae grows industrially, and thus sewage is effectively purified through a large amount of the microalgae. The invention further provides a sewage purification method, the method is simple in step, aquaculture wastewater and domestic sewage can be purified in a targeted mode, and pollution treatment is clean and effective.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a facultative microalgae photobioreactor sewage purification system and method. Background technique [0002] The discharge of aquaculture wastewater and domestic sewage is an important water environment problem facing our country. According to the data in the Bulletin of the First National Pollution Source Survey: my country's aquaculture wastewater NH 4 + The annual emissions of -N and COD reached 717,300 tons and 12.68 million tons respectively, accounting for the 4 + - 78.1% and 95.8% of the total emissions of N and COD. The "Three-Year Action Plan for the Improvement of Rural Human Settlement Environment" clearly requires step-by-step promotion of domestic sewage treatment, and puts forward treatment goals for the classification of regions with different foundations and conditions in the eastern and central western regions. A few days ago, the Ministry of Ecolo...
