V. acidification precipitation method estimates economic Wastewater

   The economic benefits of acidification and precipitation treatment of wastewater include two aspects , one is the cost of treating wastewater, and the other is the income of the recovered material .

1. The cost of wastewater treatment by acid precipitation method ( unit: yuan / M 3 · million )

  Serial number   project           unit     Quantity      unit price       Amount     Remarks

1 sulfuric acid kg/M 3 6 0.8 4.8

2 lime            〃 10 0.4 4.0

3 polyacrylamide      〃 0.05 35 1.75

4 power consumption kwh / M 3 3 0.6 1.80 total installed capacity is 20KW

5 other 3.0 filters, etc.

6 labor 9 people × 20 yuan / day 100M3 1.8

70% off old fee 1.0 10 years old depreciation

6 subtotal 18.18

2. Acidification precipitation method recovery value ( yuan / M 3 )

  Serial number   project           unit      Quantity      unit price       Amount    Remarks

1 Copper in copper slag kg/M 3 0.75 15 11.25

2 recovery of cyanide      〃 1.8 14 25.2

3 recovery gold g/M 3 0.02 75 1.5

4 subtotal 37.95

    The economic benefits of acidification and precipitation treatment of wastewater :

    Recovering the value of useful substances in wastewater by acidification and precipitation method - total cost of acidification precipitation method

=37.95 — 18.18 =19.77 yuan / M 3

    According to this calculation , the annual production of 320 days , can be profitable 630,000 yuan . Less than one year will be able to recover all equipment investment .
