For the whole plant wastewater of the photovoltaic/new energy industry, it performs classified and quality-based treatment, and provides integrated solutions and services.
l Whole plant wastewater solutions for the photovoltaic industry (polycrystalline silicon)
"Level-2 calcium addition treatment + denitrification pool + aeration tank + filtration" combined process for the treatment of fluorine-containing wastewater and ammonia-nitrogen-containing wastewater;
Advanced fluorine removal process for photovoltaic wastewater, ensuring that the stability of F- in wastewater is less than 3 mg/L by adding the advanced fluorine removal agent;
Thin film photovoltaic industry - treatment and zero discharge scheme of cadmium-containing wastewater
Key technology I:A new high-temperature filtration technology used for the treatment of thin-film photovoltaic cadmium-containing wastewater
Key technology II:A recycling technology of ammonium hydroxide from thin-film photovoltaic high-concentration ammonia-nitrogen-containing wastewater
Key technology III:A new advanced oxidation technology used for the treatment of thin-film photovoltaic thiourea wastewater
Key technology IV:A study on the coupling technology for recycling and zero discharge of thin-film photovoltaic wastewater
Technological advantages:
Able to achieve the effluent Cd<0.01 mg/L; NH3-N<30 mg/L; COD<100 mg/L;
Able to recover cadmium sulfide and 16-19% stronger ammonia water; Achieve the zero discharge treatment of wastewater;
Compared with the general treatment scheme "coagulation sedimentation + ammonia still process + Fenton", the mud production is reduced by 50-60%; the dosing cost of agents is reduced by 30-40%; and the operating cost is reduced by 30-40%.
