How is wastewater treated? 1. Wastewater volume: 50-70 m3/T. 2. The composition of the wastewater is as follows: COD: 10,000–13,000 mg/l, BOD: 6,000–8,000 mg/l, H-N: 100–300 mg/l, total P: 20–40 mg/l. 3. Emission standards: **Standards for agricultural irrigation water. 4. Investments should not be too large (for private enterprises).
If an evaporator is used, it will drive the other party crazy due to the high operating costs; it is recommended that the owner find a suitable water treatment company. Everything I’ve said here is meaningless. Because even in private enterprises, equipment and process control are still necessary
A set of biochemical systems might solve it.
Burn it up. Or biochemistry. But with such high COD levels, biochemical treatment is quite difficult
Zero-emission processes generally involve biochemical treatment first, followed by a membrane system, and finally evaporation of the concentrated water.
It is necessary to specify the components of the water quality; what organic substances are mainly responsible for the COD?
As long as it’s not COD or BOD contributed by fungicide components, then biochemical analysis is relatively simpler~~
It is a coffee production company; according to the owner, COD is primarily generated during the peeling process of the coffee beans.
The water volume isn’t very large; if the owner has excess steam and boilers, they can use evaporation for concentration and then proceed with incineration.
