UGPCB 폐수 처리 시스템: Setting New Benchmarks for Green Manufacturing in the PCB Industry

Equipment Overview and Core Technology Analysis

UGPCB employs a modular intelligent wastewater treatment system, specifically designed to address the high heavy metal and organic pollution characteristics of the PCB 산업. This system integrates three core technological modules: chemical precipitation, membrane separation, and IoT monitoring. It achieves the following:

• Heavy metal removal rate ≥ 99.8% (compliant with GB21900-2020 Table 3 표준)

• CODcr treatment efficiency of 92% (exceeding the “Electronic Industry Pollutant Discharge Standards”)

• 100% 구리 회수율 (achieved through electrodeposition technology for resource recycling)

The system utilizes an IoT-based intelligent control system to monitor over 20 parameters in real time, including pH levels, heavy metal concentration, and flow rate. Data is uploaded to a cloud platform, 활성화:

• Remote fault diagnosis (response time ≤ 15 분)

• Intelligent optimization of chemical dosing (reducing chemical usage by over 30%)

• Dynamic energy consumption adjustment (power consumption ≤ 3.5 kWh per ton of water treated)
