WASTEWATER TREATMENT APPLIANCE CAPABLE OF PRODUCING BIOGAS AND LIQUID FERTILIZER WITH HIGH QUALITY AND IMPROVING WATER QULAITY ON DISCHARGING

摘要

PURPOSE: A waste water treatment facility is provided to simplify the structure of facility and reduce operation costs by injecting raw material to an anaerobic digestion tank without a preprocessing facility. CONSTITUTION: A waste water treatment equipment includes an anaerobic digester(50) which generate bio gas by executing an anaerobic digestion process for the raw material, a blower for transferring the produced bio gas, an adulteration/solid removing device(53) eliminating the adulteration in the fire-extinguishing waste water, a first filter(57) which sends back filtered concentration solidity to the anaerobic digester, and an aerobic reactor(61) which inflows the processing water to the first filter.
