T/CSES 19-2021 Rural sewage treatment technology verification and evaluation specifications

Scope

Main technical content: To ensure the scientificness and standardization of the verification and evaluation of rural domestic wastewater treatment technologies, based on the characteristics of rural domestic wastewater treatment technologies, the working conditions that should be met during verification and evaluation are specified. Three types of indicators, including environmental effect indicators, process operation indicators, and maintenance management indicators, are designed to establish a three-level indicator system. A testing method mainly based on quantitative analysis and supplemented by qualitative description is determined, and the testing cycle, sampling frequency, and determination principles of sampling points during laboratory verification and on-site verification are specified respectively. A verification and evaluation method system based on rural domestic wastewater treatment technologies is established. On the basis of statistical analysis of test data, the performance declaration rate, pollutant removal rate, resource utilization effect, treatment effect stability, operation reliability, maintenance and management convenience, and economic efficiency of rural domestic wastewater treatment technologies are evaluated. Specific technical content includes: (1) Scope; (2) Normative reference documents; (3) Terms and definitions; (4) General principles; (5) Data collection; (6) Working condition requirements; (7) Verification test indicators; (8) Verification test cycle, sampling frequency, and sampling points; (9) Sample collection and storage; (10) Verification test methods; (11) Verification data evaluation; (12) Appendix A - Sewage flow measurement method; (13) Appendix B - Volatile fatty acid (VFA) detection method; (14) Appendix C - Power consumption measurement method
