A method for sewage treatment contacts the sewage with active carbon. The sewage flow speed is no bigger than 0.05m / min and the sewage flux, the sewage flux on per meter active carbon sectional area is no bigger than 1m3 / h, wherein the granular diameter of the active carbon is no bigger than 20 meshes. The invention relates to an active carbon absorbent bed, the top of which is provided with an open structure and the base of which is provided with a tapered structure and also with over one discharge mouthes. The bed is filled with active carbon with the granular diameter no bigger than 20 meshes. The four sides and center of the bed top are provided with a catch basin, the near-bed side of which is a outlet branch and the lower level of the outlet branch is on the same horizontal line of the lower level of the catch basin. The lower end of the bed is connected with a plurality of inlet pipes. The inlet pipes are distributed with inlet holes. An end of the inlet pipes is connected with the inlet branch passing through the bed wall and the other end of the inlet pipes is connected with the sewage valve passing through the bed wall. The active carbon asborbent bed is provided with a discharge washing pipe in the lower center and the discharge washing pipe is provided with a spray nozzle.

Efficient machining method of controllable ablation unmanageable metallic material based on electric-spark induction is characterized by comprising the following steps of: rotating a conductive roulette at a high speed, producing spark discharge between conductive teeth of the conductive wheel disc and the unmanageable metallic material under the action of a direct-current power supply or pulse power supply, meanwhile continuously or periodically introducing combustion-supporting gas which can produce combustion heat release effect through reacting with the unmanageable metallic material intoa processing area so that the processing area of the unmanageable metallic material is in states of discharging induced by electric spark, ablating and softening and machining. Based on the discharging function of the electric spark, the surface of metallic material has a temperature higher than ignition temperature and in state of activation, has an ablation reaction with combustion-supporting gas to generate an ablation product and release a large quantity of heat; the heat acts on the material base in the processed area so that the unmanageable metallic material is heated, softened and even in a molten state; the ablation product and softened or even molten metallic material is removed through abrasive particles on the wheel disc or mechanical cutting function of the cutting tooth. Themethod has advantages of high processing efficiency, low power consumption, environmental friendliness and high safety, and is especially suitable for machining of the unmanageable metallic material.
