one side of the sealed shell 1 is communicated with a water inlet pipe 6, the water inlet pipe 6 is provided with a water inlet valve 7, the water inlet pipe 6 is communicated with a bypass pipe 8, and the bypass pipe 8 is provided with a bypass valve 9;

the water inlet valve 7, the bypass valve 9, the mud valve, the standby mud valve, the temperature-controlled automatic mud discharging system and the mud dredging system are electrically connected with the control system. The control system adopts a PLC electrical control cabinet.

As shown in fig. 7, in the specific implementation, the temperature-controlled automatic sludge discharge system includes five temperature sensors, which are a first temperature sensor 27, a second temperature sensor 28, a third temperature sensor 29, a fourth temperature sensor 30 and a fifth temperature sensor 31 from bottom to top, and under the normal operation condition, sewage enters the sealed shell 1 through the water inlet pipe 6, the sewage temperature is 40-60 ℃, and a sludge layer is gradually formed at the bottom of the sealed shell 1 along with the transition of the operation time. According to water treatment process design demand, in order to avoid mud to continuously pile up in sealed casing 1, simultaneously for the mud jam reservation mediation time, the optimum critical value of mud emission is: setting that sludge needs to be discharged when a mud-water interface of a sludge layer reaches a position between the second temperature sensor 28 and the third temperature sensor 29, wherein the temperature difference (about 25 ℃/50 ℃ respectively) is formed between the second temperature sensor 28 and the third temperature sensor 29 due to different heat transfer efficiencies of heat in water and sludge, namely, the mud-water interface is proved to be between the second temperature sensor 28 and the third temperature sensor 29, the signal is input to a control system, and the control system controls the opening of the sludge discharge valve 4 to discharge sludge. The mud-water interface gradually descends along with the continuous mud discharging, the discharge can be stopped when the mud-water interface is at the first temperature sensor 27, the temperature of the first temperature sensor 27 is increased to a certain temperature (about 50 ℃), and the mud discharging valve 4 is controlled to be closed after the control system receives the temperature change information. Or the mud valve 4 is set for a certain mud continuous time, and the mud valve is closed after the time is up.
