- Abstract:
- With the rapid advancement of synthetic biotechnology, wastewater generated by the synthetic-biology industry has become a bottleneck for sustainable development due to its complex composition and high treatment difficulty. To address the technical challenges of achieving zero-liquid discharge for such wastewater in China, this paper examines a full-scale wastewater treatment and zero-liquid discharge project located in a synthetic-biology eco-industrial park in northern China. The project implements an integrated technical system consisting of “quality-based segregation and pretreatment + advanced biochemical treatment + membrane concentration + salt separation evaporation and crystallization”. The project has a design treatment capacity of 14.40×104 m3/d, with a total investment of 3.254 billion CNY. Through significant revenue generated from biogas utilization, reclaimed water reuse, and sales of sodium chloride and sodium sulfate, the comprehensive costs have been notably reduced, resulting in an actual treatment cost of approximately 33.53 CNY/m3.
