Waste water zero discharging system

The invention discloses a waste water zero discharging system. Macroporous adsorption resin is firstly used for treating and adsorbing organic matters, a filter liquor obtained after filtration and separation is treated to recycle heavy metal by using a metal trapping agent, practical anion exchange resin is used for recycling anions after filtration and separation, and then the PH value is adjusted so that the filter liquor enter into a cooling water circulating system, the filter slag of the organic maters after filtration can be used for combustion and burning, the filter slag containing metal ions is added into a metal recycling system for metal recycling, the filter slag containing the anions is desorbed, the desorbed solution is used for preparing acid, and the anion exchange resin can further be used for cyclic utilization. The system is simple in operation and easy to realize, various resources are effectively recycled, cyclic utilization is realized, and the system is environmentally-friendly and ene
