Embodiment
[0021] The membrane bioreactor process is used to treat wastewater from a certain hotel, and the volume of treated wastewater is 60m 3 / d, the COD concentration is 300-500mg / L, and this intelligent control system is used to automatically regulate the membrane bioreactor.
[0022] Automatically collect information through online monitoring instruments. When the mixed liquid sludge concentration exceeds 10g / L, the expert system automatically starts the sludge discharge pump to discharge the sludge until the sludge load rises to 0.35kgCOD / kgMLSS·d, and then automatically shuts down the sludge discharge pump. When it is monitored that the sludge load is less than 0.3kgCOD / kgMLSS·d for 4 consecutive hours, or the sludge load is less than 0.3kgCOD / kgMLSS·d for 5 times within 24 hours, the sludge discharge pump is automatically started to discharge the sludge until the sludge load rises As high as 0.35kgCOD / kgMLSS·d, the sludge discharge pump will be automatically shut down.
