Abstract

The invention provides a water treatment and recovery device and a water treatment and recovery method based on a metal-air battery. The water treatment and recovery device comprises a power generation system, an energy storage system and a water treatment and recovery system, wherein the power generation system comprises a corrosive metal negative electrode, an air diffusion positive electrode and a cavity, the corrosive metal negative electrode and the air diffusion positive electrode are oppositely arranged and form a closed container together with the cavity, the outer side of the air diffusion positive electrode contacts air, the power generation system is in circuit connection with the energy storage system through the corrosive metal negative electrode and the air diffusion positiveelectrode, a switch is arranged between the power generation system and the energy storage system and used for switching the positive electrode and the negative electrode of the power generation system and adjusting the charge-discharge state, the power generation system is connected with the water treatment and recovery system through a pipeline, and the water treatment and recovery system comprises a circulating pump, a tank body and a crystallization filter. The device can realize self-supply of electric energy and water treatment and resource recovery without addition of foreign aid chemical substances.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a metal-air battery-based water treatment recovery device and a method thereof. Background technique [0002] In recent years, the development of new sustainable water treatment technologies has become a research hotspot in the field of water pollution control. The key point is how to realize the efficient recovery of potential nutrients such as ammonia nitrogen and phosphate in wastewater and the effective removal of refractory organic matter in wastewater. Ammonia nitrogen and phosphate are key indicators of water pollution control and the main cause of water eutrophication. At the same time, ammonia nitrogen and phosphate are important fertilizers or raw materials for agriculture and chemical industries. Therefore, if the high-concentration nitrogen and phosphorus in wastewater are efficiently recovered, sustainable development of wastewater treatment can be achieved....
