High-efficient to modify fibre ball strain material apply to the meticulous filtration including oily water of oil field, suitable for the meticulous treatment of the industrial sewage of other occasions too.

    The mechanism of getting rid of the oil and impurity of fibre ball is to modify: Intercept directly , inertia is intercepted and absorbed with electrochemistry. Water quality included oil ?ü 15mg/l, ?ü 10mg/l of suspended substance before straining; Water quality includes oil ?ü 5mg/l, ?ü 2mg/l of suspended substance, ?ü 2|ìm of a drop of material after straining.

   The fibre ball surface is dealt with through modifying, the ability of absorbing to the oil and impurity is strengthened; Fibre ball new-type ligature way, strain one layer of space rate to reduce gradually along the rivers direction while running , have formed more ideal straining the hole with large top and small bottom of material and distributing the state, filtering the result is better; It is high to strain the speed , can reach 25-30m/h . It only takes supplementary about 10% for every year to strain the material , does not need to change.

    Modify fibre silk after is it dredge oilly while being hydrophilic to have , inverse well-flushing is of good performance in regeneration, it is that the more ideal one is suitable for the products of meticulous filtration including oil sewage disposal at present
