During the use, sewage that produces among the rubbish compression process flows into sewage treatment plant's sewage collection box 1 through the pipeline, and solid impurity in the sewage sinks gradually through self action of gravity, reachs desilting mouth 12 of sewage collection box 1 bottom, and wherein, set up ultrasonic sensor 15 on the sewage collection box 1 lateral wall shell for detect whether solid impurity in the sewage collection box 1 fills up. The working principle is that ultrasonic waves can penetrate through the metal wall of the sewage collecting tank, and the triggering condition of the ultrasonic waves needs to be shielded by non-light-transmitting substances with certain thickness, such as solid impurities in sewage.

The liquid in the sewage flows into the filtered water collection tank 3 through the multi-stage filtering device 2. And (3) opening the water pump 31 at the top of the filtered water collection tank 3, conveying the filtered water to the permeable membrane pipeline for permeation treatment, detecting and judging whether the water quality reaches the standard or not by the water quality detection sensor 33 after the permeation treatment is finished, discharging the filtered water meeting the discharge standard through the sewage discharge port 35, returning the filtered water not meeting the discharge standard to the filtered water collection tank 3 through the permeable membrane pipeline, and repeating the steps for retreatment.

Fig. 6 is a second embodiment of the present invention, which is different from the first embodiment in that the multistage filtering device 2 in the second embodiment includes a separate filter installation case and a filtering layer. Wherein, first filter layer is independently installed at first net box, and the second filter layer is independently installed at the second net box, and the third filter layer is independently installed at the third net box. During assembly, the first net cage, the second net cage and the third net cage are sequentially arranged in multiple layers from the sewage collecting box to the filtering collecting box or the second net cage and the third net cage are additionally arranged on the basis and are alternately arranged.

According to wet garbage data collected in rainy days of a multi-year garbage station, the compression dehydration amount of the household garbage is known to be 5% -18%, and the average water content is not more than 10%. The content of solid impurities (mud content) in the garbage water is less than 1 percent. Most garbage collection stations have the maximum daily transport capacity of less than 10 tons, so the daily average dewatering amount is less than 1 ton, and the daily average desliming amount is less than 10 kilograms. The treatment capacity of the sewage treatment plant is thus guaranteed to be above 125 kg per hour, which is fully met by the sewage treatment plant according to the utility model.

Special conditions are considered, the requirement on labor intensity is reduced, and the volume of the sewage collecting box is ensured to be more than or equal to 1 cubic meter, so that the use requirement of cleaning once in a month can be met. Multistage filter equipment washs or changes according to actual conditions, and the filter layer washs once every month, and wherein the suggestion is changed after the activated carbon layer washs six times, and suggestion once a year is changed when coarse effect filtration sponge layer and high density filtration sponge layer do not damage. The permeable membrane pipeline is properly increased and decreased in cleaning period according to the data of the water quality detection sensor, and is recommended to be replaced after being used for two years.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
