When the water pump 3 conveys the pollution-free clean water obtained by treatment in the sewage tank 1 to the clean water tank 6 through a pipeline, the water quality detector 4 detects the water passing through the pipeline when the water passes through the water quality detector 4, if the water quality detection result is within the standard value range, the sluice 5 is opened, and the clean water can directly flow into the clean water tank 6 through the pipeline. If the detection result of the water quality detector 4 on the clean water is not in the standard value range, the water quality detector 4 sends out a warning signal, the sensor on the sluice 5 closes the sluice after receiving the warning signal, and the clean water cannot flow into the clean water tank 6 through the pipeline.
When the clean water with the detection result within the standard value range flows into the clean water tank 6, the water in the clean water tank 6 is conveyed to a pond or a river according to the requirement for aquaculture.
The sewage outlet plug 15 at the bottom of the sewage tank 1 is opened, the treated sewage settled at the bottom of the sewage tank 1 is discharged into the fermentation tank 7 through the sewage outlet, scale marks are marked on the tank wall of the fermentation tank 7, decomposing bacteria are put into the fermentation tank 7 according to a certain proportion according to the volume of the entered sewage, the decomposing bacteria can ferment, eat, corrode and plant the sewage in the fermentation tank 7 without the sewage to generate methane, and the methane generated in the fermentation tank 7 is conveyed into the methane tank 8 through a gas conveying pipeline, so that the domestic gas can be used.
Sludge generated after fermentation in the fermentation tank 7 is fertilizer rich in soil nutrients, and can be used for feeding earthworms which can be used for feeding fishes and shrimps after growing up.
