External circulation anaerobic reactor ECAR: ECAR makes full use of anaerobic granular sludge technology to provide a sufficient upward flow rate for the reactor through external circulation, maintain the expansion of the granular sludge bed and mixing inside the reactor, and improve the processing efficiency of the reactor. High-concentration wastewater is pumped from the bottom of ECAR by the water distribution system and fully mixed with the anaerobic granular sludge in the reactor. Most of the organic matter is converted into biogas. The gas-liquid separation module achieves good separation of biogas, water and sludge. The biogas enters the biogas delivery system from the top, and the wastewater flows into the subsequent treatment system from the water outlet pipe, and the anaerobic sludge flows back to the sludge bed. It is suitable for the treatment of high-concentration organic wastewater such as starch wastewater, alcohol wastewater and other light industry foods.

Application situation or application prospects: The company is a professional environmental protection company specializing in environmental protection technology development and consulting, environmental protection engineering design and contracting, environmental protection equipment integration and sales, and environmental protection facility operation. After years of development, the company has gradually formed an industrial structure with biological sewage treatment as the leader, biogas biological desulfurization and environmental protection equipment as the two wings, and environmental protection facility operation and management as the backing. The business areas cover sewage treatment, pure water treatment, reclaimed water reuse, sludge treatment, waste gas treatment, biogas desulfurization, sales and custody operations of environmental protection equipment.
