Sewage treatment system for regenerative resource power supply

Abstract

A sewage treating system for power supply by re-generative resources consists of electrolytic sewage sewage-treating tank with at least solar cell, hydrogen purifier, hydrogen storage tank and fuel battery set. The top outlet of cathode cavity of electrolytic sewage-treating tank is communicated with hydrogen purifier and hydrogen storage tank by pipeline, then connected with fuel inlet of fuel battery set, and the said electrode of electrolytic sewage-treating tank is communicated with paralleled solar cell and fuel battery set. It can be used to supply power by solar energy, collect and purify the generated hydrogen as resources of fuel battery set and convert hydrogen energy into electric energy. It has electric power saving and no environmental pollution.

Description

【Technical field】 [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment system powered by renewable energy. 【Background technique】 [0002] Electrolytic sewage treatment (electrochemical sewage treatment) is an important method of sewage treatment. Because the cleanest "electron" is used as the reaction reagent in the electrochemical treatment process, the electrochemical sewage treatment method has become a safe and simple operation method. And it is an environmentally friendly sewage treatment method. Especially in recent years, the introduction of diamond electrodes into the sewage treatment process has been studied at home and abroad, which overcomes the reduction of electrode activity caused by the adsorption of reactants and reaction intermediates on the electrode surface of traditional electrodes, which reduces the electrolysis efficiency of the electrode, and also shortens the length of the electrode. Moreover, its oxidiz...

AI Technical Summary

Problems solved by technology

Especially in recent years, domestic and foreign studies have begun to introduce diamond electrodes into the sewage treatment process, which overcomes the decrease in electrode activity caused by the adsorption of reactants and reaction intermediates on the electrode surface of traditional electrodes, which reduces the electrolysis efficiency of the electrode and shortens the electrode life. The service life and other issues, and its strong oxidation ability, thus opened up a new direction for the electrochemical treatment of organic polluted wastewater, showing broad prospects

However, the use of diamond electrode electrolysis for sewage treatment consumes a lot of power, and the current electrochemical treatment of sewage uses conventional energy for power supply, and the hydrogen produced in the process of electrolytic sewage treatment has not been utilized.

Therefore, this sewage treatment method also consumes and wastes a large amount of energy
