Embodiment 1
[0031] A method for preparing a renewable fiber ball filter material for oily sewage treatment, the innovation of which is to include the following steps:
[0032] 1) Activation: Take 10 kg of fiber ball raw materials, such as figure 1 As shown in a), place it in a constant temperature box for constant temperature activation at 90°C;
[0033] 2) Reaction: Take out the activated fiber balls and place them in a 1000L stainless steel high-pressure reactor, and feed ammonia gas with a temperature of 120°C and a flow rate of 1kg / min and a pressure of 0.2MPa and a flow rate of 1kg / min into the stainless steel high-pressure reactor React with water vapor, control the reaction temperature in the stainless steel container to 120°C, and end the reaction after 20 minutes;
[0034] 3) Washing: Take out the fiber balls and immerse them in ionized water, stir and wash them at a low speed of 800-1000r / min for 30min, and then dry them by centrifugation;
[0035] 4) Drying: put the dried fib...
