During the environmental protection acceptance inspection upon the completion of a construction project, for wastewater sources with stable production and regular pollutant emissions, the sampling period shall be based on the production cycle, with no fewer than ( ) such cycles of sampling to be conducted, 3 to 5 times per cycle. A. 2 B. 3 C. 4 D. 1 Correct answer: A. Explanation: See page 464 of the technical methods textbook: 5. Technical requirements for wastewater monitoring (1) Monitoring points: The inlets and outlets of each treatment unit in wastewater treatment facilities, the emission outlets of workshops where Class I pollutants are generated or of the treatment facilities within such workshops, the discharge outlets for industrial wastewater, domestic wastewater, and clean effluent, as well as rainwater discharge outlets. (2) Monitoring factors: The monitoring factors for the inlet and outlet of treatment facilities are determined based on the types of pollutants primarily treated by the facilities ； The determination of the monitoring factors for exhaust outlets shall refer to the relevant pollutant emission standards. (3) Monitoring frequency. ‘ ♦For emission sources with stable production and regular pollutant emissions, the production cycle shall be used as the sampling period; sampling should be carried out for no less than 2 cycles, with the number of samples taken per sampling cycle generally ranging from 3 to 5 ； ♦For construction projects that have sewage treatment facilities in operation or retention tanks, since the sewage discharge is steady, instantaneous samples can be taken, but the number of such samples must be no less than 3 ； For intermittent discharge volume
Sampling must be no less than (a) cycles
During the environmental protection acceptance inspection upon the completion of a construction project, for wastewater discharge sources with stable production and regular pollutant emissions, the sampling period shall be based on the production cycle, with samples to be taken no fewer than (A) cycles, at 3 to 5 times per cycle.
