Abstract

The invention relates to an electrochemical treatment system for source-separated urine flushing water and an electrochemical treatment method thereof. The electrochemical treatment system includes electrolytic cell I and electrolytic cell II; the porous titanium rod anode I of electrolytic cell I is placed in the stainless steel cathode tube I of electrolytic cell I, and the structure of electrolytic cell II is the same as that of electrolytic cell I; The water pool is connected to the water inlet of electrolytic cell Ⅰ through a water pump, the anode water outlet of electrolytic cell Ⅰ returns to the sedimentation storage tank through magnesium source reactor Ⅰ, the cathode water outlet of electrolytic cell Ⅰ is connected to the water inlet of electrolytic cell Ⅱ, and the water outlet of electrolytic cell Ⅱ The anode water outlet returns to the sedimentation storage tank through the magnesium source reactor II, and the cathode water outlet of the electrolytic cell II returns to the sedimentation storage tank. The present invention is based on the nutrition of a large amount of nitrogen and phosphorus resources contained in urine, and from the perspective of resource recovery and reuse and energy saving, the fundamental purpose of the invention is to solve the separation and utilization of nitrogen and phosphorus resources in urine cleaning water from source separation and the recycling of water.

Description

technical field [0001] The invention relates to an electrochemical treatment system for source-separated urine flushing water and an electrochemical treatment method thereof. Background technique [0002] Since the end of the 20th century, scholars in Sweden, Germany, Switzerland and other countries have successively proposed related technologies for collecting and treating domestic sewage from the source, among which source separation technology has been vigorously promoted in the application of ecological toilets. However, a major problem facing the promotion of the current source-separated ecological toilet drainage system is that after the source is separated, the large amount of urine flushing water containing high concentrations of nitrogen and phosphorus cannot be effectively stored, treated and utilized. It may become a secondary pollutant, so that the superiority of the source separation ecological toilet drainage system cannot be reflected. Therefore, it is of gre...
