The invention relates to a method for processing reverse osmosis concentrated water by a catalyzed internal electrolysis and modified biological aerated filter. The method comprises the following steps: 1) performing catalyzed internal electrolysis pre-processing: regulating a pH value of wastewater, and removing organic substances in concentrated water through iron-carbon internal electrolysis reaction; 2) performing two-stage biological filter biological membrane processing: after performing coagulating sedimentation on catalyzed internal electrolysis outlet water, introducing the catalyzed internal electrolysis outlet water into a two-stage biological filter (a denitrification biological filter and an aeration biological filter) to further remove organic substances and ammonia nitrogen in the concentrated water. The method is high in processing efficiency, low in operation cost and capable of effectively removing organic substances which have toxic action to human health and an ecological environment in the concentrated water and improving wastewater biodegradability; the improved aeration biological filter can be suitable for characteristics of high hardness, high alkalinity, high sulfate and the like of the RO concentrated water, so that the water quality of the outlet water meets emission needs and a novel way for processing the reverse osmosis concentrated water is provided.

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.
