1、 Industry pain point: Why is pesticide wastewater treatment difficult?    

        Chemical pesticide wastewater, due to its complex composition, high toxicity, and high salt content, has become a "hard bone" in environmental protection management;  

      -  Complex composition: containing recalcitrant pollutants such as organic phosphorus, sulfides, and benzene derivatives, with a traditional COD removal rate of less than 30%;    

      -  High salt problem: salt concentration exceeding 3% leads to the collapse of the biochemical system, and evaporation equipment is prone to scaling;    

      -  Cost pressure: The cost of chemicals and sludge disposal accounts for over 50%, and environmental protection investment becomes a burden for enterprises;    

      -  Policy risk: The "Pesticide Industry Water Pollutant Discharge Standards" (GB 31574-2015) require COD<100mg/L, which makes it difficult for most enterprises to consistently meet the standards.    

        2、 Case background: The transformation dilemma of XX Chemical Group;  

        Company Profile: A large pesticide intermediate production enterprise in China, with an annual output of 50000 tons of wastewater.    

        Original process defect:;  

        -By using "coagulation sedimentation+activated carbon adsorption", COD only decreased from 5000mg/L to 800mg/L, far exceeding the emission limit;    

        -The sludge production is large (10 tons/month), and the disposal cost reaches 500000 yuan/year;    

        -The equipment is severely corroded and frequent maintenance affects production.    

        Transformation objective:;  

        -The COD stability of wastewater is less than 100mg/L, and the total phosphorus is less than 0.5mg/L;    

        -Reduce sludge by more than 70% and lower comprehensive treatment costs;    

        -Realize the reuse of water resources and salt, and create economic benefits.    

        3、 Baihuipu Customized Solution: Evaporation Technology+Resource Recycling Closed Loop;  

(Implant core product keywords: MVR evaporator, high salt wastewater treatment equipment)   

        1. Process flow diagram (with Alt tag "Baihuipu Pesticide Wastewater Treatment Process");  

        Pre treatment → Advanced oxidation → MVR evaporation → Crystallization recycling → Condensed water recovery;  

        2. Analysis of Technical Highlights;  

        (1) Preprocessing Upgrade: Cracking COD Difficulties;  

        -  Micro electrolysis+Fenton oxidation:;  

          Under acidic conditions, iron carbon microelectrolysis generates strong oxidative free radicals, decomposes large organic molecules, and increases COD removal rate to 65%;    

  Combined with Fenton reagent, further oxidize residual pollutants to reduce the burden on the evaporation stage.    

        (2) Core equipment: Whirlpool MVR evaporation system;  

      -  Corrosion resistant design: The evaporator is made of titanium alloy material and can withstand highly corrosive wastewater with a pH of 2-12;    

      -  Intelligent energy saving: The steam thermal energy cycle utilization rate reaches 95%, with a water and electricity consumption of only 25kW · h per ton, saving 50% of energy consumption compared to traditional evaporation;    

      -  Anti scaling technology: forced circulation+online cleaning system, reducing the risk of CaSO ₄ and silicate scaling, and extending equipment life.    

        (3) Resource Recycling Loop: Wastewater Becomes a 'Treasure';  

      -  Crystal salt reuse: NaCl and Na ₂ SO ₄ crystal purity>98%, meeting industrial salt standards, with an annual recovery of 300 tons;    

      -  Reuse of condensate water: After deep treatment by reverse osmosis system, 85% of the produced water is reused in the production line, saving 40000 tons of water annually;    

      -  Hazardous waste reduction: The sludge volume has been reduced from 10 tons/month to 2 tons/month, reducing disposal costs by 80%.    

        4、 Implementation results: Digitization witnesses a win-win situation for environmental protection and economy;
