Electrochemistry and micro-electrolysis combined garbage leachate pretreating device

The utility model discloses an electrochemistry and micro-electrolysis combined garbage leachate pretreating device. The garbage leachate pretreating device mainly comprises an electrochemical treatment device, a micro-electrolysis treatment device and two water outlet grooves, wherein the electrochemical treatment device is mainly used for removing high-concentration ammonia nitrogen in garbage leachate; then pollutants difficult to biodegrade, in the garbage leachate, are removed through the micro-electrolysis treatment device; and finally water in the garbage leachate flows out through the water outlet grooves. The garbage leachate pretreating device well plays a role in removing the pollutants of the garbage leachate and improves the pretreating effect on the garbage leachate. In the electrochemistry oxidation process, the electrolysis of ammonia nitrogen is prior to that of COD (Carbon Doped Oxide), but if COD is electrolyzed after the ammonia nitrogen is completely electrolyzed, more energy is consumed;
