The right center of the loading plate 14 is provided with a hole for connecting the pipeline 2 between the first electrolytic cell and the second electrolytic cell; holes with internal threads are formed in two ends of the loading plate 14 and used for placing screws with external threads corresponding to the internal threads, and the screws can be screwed into a wall behind the urinal, so that the loading plate 14 is fixed, and the first tank body 16 is further fixed.
The first anode electrode 3 and the second anode electrode 5 are made of foam nickel, carbon cloth or ruthenium iridium titanium mesh. When the foam nickel is used as a catalyst carrier, the foam nickel has a higher porous structure, so that the attachment sites of the catalyst are greatly increased, the attachment of the nickel hydroxide catalyst is facilitated, the active surface area of an electrode is increased, and the urea in urine can be efficiently decomposed by electrocatalysis.
The first cathode electrode 4 and the second cathode electrode 6 are made of graphite, stainless steel, carbon cloth or copper.
The principle of the invention is as follows:
the device for degrading urine in situ in the urinal can be directly connected with the urinal through a sewer pipe and arranged below the urinal, and the catalyst is attached to the anode electrode and can generate electrochemical reaction under the electrified condition to electrically catalyze the urea decomposition. Urine flows into the first electrolytic cell through a sewer pipe, and under the electrified condition, the cathode and the anode respectively generate a hydrogen evolution reaction and an electrocatalytic decomposition urea reaction, so that the aim of in-situ decomposition of urea is fulfilled. When the water level of the treated wastewater reaches a certain scale, the electromagnetic valve 15 is opened, and the wastewater after the primary treatment is discharged into the second electrolytic cell through the pipeline 2 for secondary treatment so as to achieve higher urea removal rate. The waste water after twice treatment is discharged into the urban waste water centralized pipeline through an underground drainage pipeline. Meanwhile, when the first electrolytic cell and the second electrolytic cell are electrified to work, the hydrogen collector 7 can also simultaneously collect hydrogen generated by hydrogen evolution reaction and discharge the hydrogen into the gas collecting bottle through the collecting pipeline, so that potential safety hazards caused by the generated hydrogen are prevented. This device has carried out the preliminary treatment to urine waste water, has degraded partial urea in order to reduce the residual rate of urea among urinal and pipeline to reach and reduce the microorganism and breed and reduce the purpose of the peculiar smell of production.
The above-mentioned embodiments are preferred embodiments of the present invention, and the present invention is not limited thereto, and any other modifications or equivalent substitutions that do not depart from the technical spirit of the present invention are included in the scope of the present invention.
