[0021] Furthermore, an open box 14 is fixedly installed on the water storage tank 10, and a cold air blower 15 is fixedly installed on the open box 14.

[0022] By activating the air cooler 15, air can be drawn in, converted into a cold airflow, and blown out through the open box 14 to the position above the water storage tank 10, thereby accelerating the cooling of the water source in the water storage tank 10 and improving the cooling effect of the water source on the bend pipe 8.

[0024] The design of the gas guide pipe 16 allows the gas to enter the bottom of the solution in the reaction chamber 2, thereby enabling the gas to fully react with the solution in the reaction chamber 2 during the gas flow process.

[0025] Furthermore, a cover plate 17 is hinged to the top of the reaction chamber 2, and a feeding port 18 is fixedly installed on the cover plate 17.

[0032] Then under acidic conditions, an excess amount of iodine is added to the reaction box 2, the sulfide reacts with the excess amount of iodine, the remaining iodine is titrated with sodium thiosulfate solution, starch is used as an indicator, the amount of sodium thiosulfate solution consumed is used to indirectly obtain the amount of sulfide, and the reaction equation is as follows:

[0033] S 2- +Zn 2+ →ZnS↓;

[0034] ZnS+I2→Zn2+2I - +S↓;

[0035] I2+2S2O3 2- →2I- + S4O6 2-
