[0028] Waste liquid treatment structure, waste liquid treatment structure includes the raw water bucket 11 being set, the water storage tank 12 being set in the side of raw water bucket 11, the steam pipeline 13 being communicated in raw water bucket 11 and water storage tank 12, the heat pump compressor 14 being set between raw water bucket 11 and water storage tank 12, the concentrated liquid circulation pipe 15 being communicated in the side of raw water bucket 11, the concentrated liquid water outlet 16 being communicated with concentrated liquid circulation pipe 15, the waste liquid inlet pipe 17 being communicated in the bottom surface of raw water bucket 11, the condenser 18 being communicated with raw water bucket 11, the expansion valve 19 being communicated with condenser 18, the vacuum pump 110 being communicated with water storage tank 12 and clean water outlet pipe 111, the evaporator 112 being set in raw water bucket 11;

[0029] In specific use, the waste liquid of laboratory is input to raw water bucket 11 by waste liquid inlet pipe 17, vacuum pump 110 runs to generate vacuum, evaporator 112 automatically feeds water, heat pump compressor 14 runs to generate heat to heat wastewater in raw water bucket 11, under vacuum state, wastewater temperature rises to about 30 DEG C, wastewater starts to evaporate, preheating is completed, the temperature of evaporator 112 is set to 35-40 DEG C, heat pump compressor 14 compresses refrigerant to generate heat, while water evaporates rapidly, refrigerant absorbs heat to refrigerate after gasification through expansion valve 19, steam rises and liquefies into water storage tank 12 clean water, clean water is discharged through clean water outlet pipe 111, refrigerant absorbs heat, is compressed by heat pump compressor 14 to heat, to reheat waste liquid, waste liquid evaporates to a certain concentration, concentrated liquid is discharged through concentrated liquid water outlet 16, after one evaporation cycle, heat pump compressor 14 stops working, pneumatic valve at concentrated liquid circulation pipe 15 opens, raw water bucket 11 starts to pressurize, and concentrated liquid is pressed into concentrated barrel to be handled externally.

[0030] Further, through the sampling assembly, the steam generated by evaporation can be directly and quickly sampled to determine whether the purified water meets the discharge standard. Such sampling is more standard. If sampling is performed at the position of the purified water outlet pipe 111, the sampling result will be affected when the water storage tank 12 is contaminated.

[0031] Specifically, the sampling assembly comprises a sampling pipe 21 connected to the bottom surface of the steam pipe 13, a threaded plug 22 connected to the sampling pipe 21, and an arc-shaped flow collector plate 23 connected to the top end of the threaded plug 22.
