The steam generated by heating enters the separation pipe 52 through the first connecting pipe 51, which will be cooled for further separation. The steam rises and enters the compressor 54. The compressor 54 is started. The compressor 54 absorbs and compresses the hot steam to increase the pressure and temperature of the steam, and then enters the steam pipe 3 through the output pipe 55, and then the steam is recycled, thereby avoiding the need for the evaporator used in general sewage treatment to heat and evaporate sewage through steam. With the continuous input of sewage, steam must also be continuously generated. The steam after heating and evaporation is usually directly discharged, which makes it difficult to continuously use the steam, resulting in an increase in the amount of steam used, resulting in a higher sewage treatment cost.

When the sewage passes through, flocculant can be added through the liquid inlet pipe 2, and the first motor 59 is started. The output shaft of the first motor 59 drives the stirrer 510 to rotate, and then the flocculant and the sewage are stirred and mixed, thereby enhancing the treatment effect of the sewage. The two liquid pumps 61 are started. The liquid pump 61 will pump the concentrated liquid in the liquid storage pipe 4 and the separation pipe 52 into the solidification box 62, which can facilitate the subsequent treatment of the concentrated liquid. The curing agent is added, and the curing agent reacts with the concentrated liquid to solidify the concentrated liquid, so that the product can be easily processed. The two sliders 65 are slid to drive the scraper 66 to push the solidified material out of the curing box 62 through the discharge chute 69. Before the reaction is completed, the baffle 610 can be slid so that the baffle 610 blocks the discharge chute 69, and the second motor 68 is started. The output shaft of the second motor 68 drives the screw 67 to rotate. Since the slider 65 slides in the slide groove 64, rotating the screw 67 will drive the slider 65 to slide, making the cleaning operation more convenient.
