NOVELTY - A coal gasified wastewater biochemical treatment equipment comprises an anaerobic biochemical treatment unit having an anaerobic biochemical reaction zone; an inner circulating system; an oxygen-poor biochemical treatment unit having oxygen-poor biochemical reaction zone; an active carrier/water separating zone; a first stage or multistage aerobic biochemical treatment unit; a device for inducing air to aerobic biochemical reaction zone; a membrane bioreactor unit; a device for inducing air to aerobic biochemical reaction zone; and a membrane component.    USE - Equipment used for biochemically treating coal gasified wastewater (claimed).    ADVANTAGE - The equipment can realize high chemical oxygen demand removing rate and high ammonia removing rate.    DETAILED DESCRIPTION - A coal gasified wastewater biochemical treatment equipment comprises:    (1) an anaerobic biochemical treatment unit having an anaerobic biochemical reaction zone, where the raw water performs the anaerobic biochemical reaction with active carrier of load anaerobic microorganism so as to obtain the first water flow;    (2) an inner circulating system, which is used for circulating a part of the first water flow into the raw water;    (3) an oxygen-poor biochemical treatment unit having an oxygen-poor biochemical reaction zone, where the other part of first water flow performs the oxygen-poor biochemical reaction with active carrier of load anaerobic microorganism;    (4) an active carrier/water separating zone, which is used for separating the active carrier with water after performing the oxygen-poor biochemical reaction so as to obtain the second water flow and returning the active carrier to the oxygen-poor biochemical reaction zone;    (5) a first stage or multistage aerobic biochemical treatment unit, which comprises an aerobic biochemical reaction zone, where the second water performs the aerobic biochemical reaction with active carrier of load anaerobic microorganism;    (6) a device for inducing air to the aerobic biochemical reaction zone, and the active carrier/water separating zone, which is used for separating the active carrier with water after performing the oxygen-poor biochemical reaction so as to obtain the third water flow and then returning the active carrier to the oxygen-poor biochemical reaction zone;    (7) a membrane bioreactor unit, which comprises an aerobic biochemical reaction zone, where a part of the third water flow performs the aerobic biochemical reaction zone with active carrier of load anaerobic microorganism;    (8) a device for inducing air to the aerobic biochemical reaction zone; and    (9) a membrane component, which is used for performing the membrane filtering to a part of water flow after the aerobic biochemical reaction to obtain the target water flow.    The active carrier/water separating zone is used for separating the active carrier and water of the other part of water flow after aerobic biochemical reaction so as to obtain the fourth water flow and then returning the active carrier to the aerobic biochemical reaction zone. The aerobic biochemical treatment unit is communicated with anaerobic biochemical treatment unit so as to circulate the other part of third water flow to the anaerobic biochemical treatment unit; and the membrane bioreactor unit is communicated with the oxygen-poor biochemical treatment unit so as to circulate the fourth water flow into the oxygen-poor biochemical treatment unit. An INDEPENDENT CLAIM is included for coal gasified wastewater biochemical treatment method.
