The present invention provides a preparation method for a modified cathode of an MEC-AD system and application of the system with high efficiency and low energy consumption. A NiCo-BDC hydrothermal carbon composite MOF material is designed and used for modifying a cathode, which can remove COD more rapidly compared with traditional AD. A wind energy and light energy complementary power generation device is used for energy supply of the MEC-AD system, and energy consumption is further reduced by setting an intermittent power supply mode. The intermittent power supply achieves higher energy recovery efficiency while obtaining higher performance, can effectively reduce energy consumption of the MEC-AD system, is conducive to more convenient configuration of a power generation and energy supply device using clean energy, and has a good application prospect in reducing COD in organic wastewater with low energy consumption and high efficiency.

Described is a method for preparation of stable fatty alcohol emulsion, wherein, fatty acid esters are introduced into an antifoaming agent emulsion system, and an anionic surfactant is added in the late stage of emulsification process in order to further improve the stability of the emulsion. The anionic surfactant is absorbed to the surface of fatty alcohol particles to make the fatty alcohol emulsion more stable under the action of ionic mutual repulsion. The prepared fatty alcohol emulsion has favorable foam elimination and suppression performance in the paper making procedure, and is stable during storage.
