Embodiment 1
[0038] Such as figure 1 As shown, the specific steps of using the pretreatment method of liquid hazardous waste of the present invention to process liquid hazardous waste are as follows:
[0039] S1: Warehousing identification: firstly identify the hazardous liquid waste from tank trucks and tons of barrels, and classify the hazard levels of liquid hazardous waste; identify and classify the hazards of the toxicity of liquid hazardous waste according to the WSDS database , among which highly toxic substances and substances with unknown components shall be sealed up and reported according to relevant specifications or returned to the original waste unit, and materials that meet the type of treatment of the unit shall be classified and recorded for storage;
[0040] S2: Treatment and storage of liquid hazardous waste raw materials: LDF coarse filter material is obtained after rough filtering the liquid hazardous waste from tank trucks and liquid hazardous waste from tons of barre...
Embodiment 2
[0052] Such as Figure 1-Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that in this embodiment, the hazard of the toxicity of liquid hazardous waste is identified and classified according to the WSDS database, and the type and hazard level of liquid hazardous waste are determined. In addition, since the liquid hazardous waste is transported by the pipeline 1 in this technical solution, in order to avoid the problem of the pipeline 1 being blocked, the connection mode of the pipeline 1 and the structure of the connector are improved.
[0053] In this embodiment, the pipeline 1 is arranged in a spliced shape in subregions, and the two pipelines 1 are communicated through a regulating valve. The regulating valve includes a fixing part and an adjusting part. The fixing part in this embodiment can communicate with the pipeline 1 The fixed ring 2, the inner diameter of the fixed ring 2 is provided with a switch valve for opening and closing the inne...
