Description

Technical Field

[0001] This utility model relates to the field of water quality analysis technology, and in particular to a dark laboratory for water quality analysis. Background Technology

[0002] Currently, traditional water quality analysis laboratories primarily rely on manual operation to complete the entire process from sample receiving, registration, dispensing, reagent addition, and injection testing to data recording and report generation. This manual-based testing model has significant shortcomings: Firstly, water quality testing involves the determination of various physicochemical indicators such as ammonia nitrogen, total phosphorus, total nitrogen, chemical oxygen demand, and heavy metals. The operational steps are cumbersome and highly repetitive, making manual operation not only labor-intensive and inefficient, but also difficult to guarantee testing cycles in the face of high-frequency, large-scale monitoring tasks. Secondly, manual operation is susceptible to the influence of personnel experience, operating habits, and fatigue levels, resulting in quality risks such as sample addition errors, cross-contamination, and data recording errors. The accuracy, consistency, and traceability of test results are difficult to reliably guarantee. In addition, some water quality testing processes require contact with chemical reagents, and long-term operation poses a potential threat to the personal safety and occupational health of testing personnel.

[0003] To address these issues, water quality testing systems centered on automated analytical instruments have emerged in recent years. However, existing systems often involve partial automation modifications for single or a few testing items, and lack a unified and efficient sample transfer and scheduling mechanism between workstations, making it difficult to cover the entire process of water quality analysis.
