Electrolytic filler qualifications within the iron-carbon micro-electrolysis filler filler integration advantages: (1) by fusing a variety of multi-metal catalyst to form an integrated high temperature melting alloy to ensure that "galvanic" effect sustainable and efficient. Like yin and yang mix does not appear as a very physical separation, the impact of the original cell reaction. (2) structure of formula in the form of a microporous structure, providing a great specific surface area and uniform air flow passage of water, wastewater treatment provides greater current density and better catalytic effect. (3) activity is strong, light weight, not passive, not compacted, the reaction rate is fast, stable and effective long-term operation. (4) a catalytic component for different ratios of different wastewater adjusted to improve the reaction efficiency, expand the range of applications for wastewater treatment. (5) During the reaction, as the anode active iron contained fillers continue to provide electronic and dissolved into the water, in the form of very small places cathode carbon particles flowing out. When after a certain period, may be achieved by way of direct investment plus supplementary packing and timely recovery system stability, but also greatly reduce the operating strength of the workers. (6) packing for wastewater collection oxidation, reduction, electrodeposition, flocculation, adsorption, bridge, volume scanning and co-precipitation-in-one. Low (7) processing costs, substantial removal of organic contaminants in the same time, can greatly improve the wastewater biodegradability. (8) The facilities and equipment can be realized type of structures to meet a variety of needs based on the size and user requirements.
