While environmental monitoring authorities at all levels devote efforts to capacity building and quality management, proper waste liquid management also deserves sufficient attention to avoid potential environmental and health risks. In collaboration with manufacturers of online water quality monitoring instruments, this article elaborates on three core principles for handling waste liquid produced during wastewater monitoring.
Build Standardized Management Rules
Environmental protection codes in many developed regions impose strict controls over waste and waste liquid management. Regulatory authorities formulate pollution supervision rules to govern various pollutants, requiring waste liquid to undergo harmless treatment prior to discharge. Staff at environmental monitoring institutions shall attach adequate importance to standardized waste liquid disposal. Facilities need to formulate targeted waste liquid management systems and technical operation specifications based on practical working conditions. Dedicated personnel shall be assigned to oversee related work, and waste liquid management shall be incorporated into routine daily administration.
Conduct Centralized Waste Liquid Disposal
Waste liquid generated from monitoring covers diverse categories yet generally comes in small volumes. Separate disposal of waste liquid after each wastewater monitoring test would create burdens on equipment deployment, time scheduling and manpower allocation. For practical operation, staff may sort waste liquid by chemical type, collect categorized waste liquid and store it in designated areas before unified treatment. During treatment processes, chemical consumption shall be controlled appropriately to lower the possibility of secondary waste liquid generation. Meanwhile, recyclable waste materials shall be recovered and reused where feasible.
Realize Reagent Recycling
Recycling chemical reagents helps lower environmental pollution and cut operational expenses for Water Quality Monitoring departments. Organic solvents that cannot directly participate in chemical reactions can be recovered through appropriate technical means for repeated utilization.
