High concentration circuit board wastewater treatment
Thread Content
Ask the experts for advice: The existing circuit board factory discharges 12,855 tons of wastewater per day, and the original treatment process is coagulation and sedimentation! Due to incomplete separation of raw water, organic wastewater and inorganic wastewater are mixed with each other, and complex wastewater and process cleaning water are mixed with each other, resulting in excessive effluent quality and high treatment costs! In order to change the current situation, the factory plans to build a new wastewater treatment facility to treat high-concentration organic wastewater and all complexed wastewater separately. The specific water quality and quantity indicators are as follows: Wastewater type Pollutant name Pollutant concentration Organic wastewater (400m3/d) COD15000mg/lPH12Cu2+2～20mg/l Waste acid PH2Cu2+5～20mg/l Complex wastewater (1800m3/d )SS60～200mg/lNH4-N20～60mg/lNi2+10～25mg/lCu2+40～100mg/lPH3～5COD200～500mg/l Total total water volume 2200m3/d
1. No matter how good the technology is, it seems to have little effect on poor front-end management. Since the poster has realized that this problem is caused by the front-end diversion problem, why not perform separate processing after diversion. Your separation of organic and inorganic wastewater can reduce the amount of flocculant added, and can also solve the problem of meeting discharge standards. It is possible that you have done a good job in the diversion above, and the problem you mentioned will be solved.
