Coal gasification wastewater
Thread Content
How much solids are generally dissolved in coal gasification wastewater? What are the approximate production figures? Thanks!
This should be related to the composition of raw coal and the gasification method used. The main solid component in gray water is mineral cinder.
This is closely related to the design, production and operation level of the gas purification system of the device； It is also related to the type of gasifier, type, composition, particle size, etc. of raw coal. The disposal of gray water is quite a hassle! It is difficult and difficult to achieve the standard.
Can you give an example and list a few sets of data to explain, thank you.
Could you please tell me what is your company’s wastewater discharge volume?
It’s more complicated, and some elements in coal will enter the wastewater:) A set of typical data of pulverized coal gasification wastewater for reference Project unit data Remarks Temperature º℃ TIC mg/L 30.00 TOC mg/L 125.00 TSS mg/L 100.00 COD ppm 300.00 BOD ppm 200.00 CN- Free mg/L 10.00 CN- Compound mg/L 25.00 SCN mg/L 5.00 Cl- mg/L 1885.00 Br- mg/L 6.00 F- mg/L 825.00 B mg/L 5.00 Se2-/H2Se mg/L 45.00 NH3/NH4+ mg/L 165.00 Total sulfur mg/L 5.00 SO42- mg/L 50.00 Na+ mg/L 1895.00 K+ mg/L 10.00 Ca2+ mg/L 400.00 Mg2+ mg/L 40.00 Fe mg/L 50.00 As mg/L 0.10 Ba mg/L 0.40 Co mg/L 0.01 Cd mg/L 0.01 Cr mg/L 1.00 Cu mg/L 0.02 Hg mg/L 0.00 Mn mg/L 0.03 Mo mg/L 0.40 Ni mg/L 0.50 P mg/L 1.00 Pb mg/L 0.10 U mg/L 0.30 V mg/L 0.05 Zn mg/L 0.02 This post was last edited by Tianya wandering on 2009-3-8 17:06 ]
Can you talk about the dissolved solid content? In other words, the solid content!
