UGPCB Effluent Treatment System

UGPCB Effluent Treatment System: 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 ثنائي الفينيل متعدد الكلور صناعة. 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 المعايير)

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

• 100% معدل استرداد النحاس (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, enabling:

• Remote fault diagnosis (response time ≤ 15 دقائق)

• 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)

Environmental Technology Advantages of UGPCB

Closed-Loop Resource Recycling System

• Wastewater reuse rate of 85%: Achieved through a combination of reverse osmosis (RO) and ultrafiltration (UF) العمليات, with treated water quality meeting GB/T 19923-2005 standards for industrial water reuse.

• Metal resource recovery: Annual recovery of 1,200 tons of copper, tin, and other metals, generating economic benefits of 24 million RMB (based on 2025 market prices).

IoT-Enabled Intelligent Operation and Maintenance

• Equipment health prediction: Utilizes vibration sensors and AI algorithms to provide early warnings of potential failures up to 72 hours in advance.

• Carbon emission management: Integrated carbon footprint calculation module displays real-time carbon emission data during the treatment process.

Certifications and Standard Leadership
