[0037] Example 6

[0038] We plan to take samples at the open flow channel at the front end of the vortex grit chamber in the wastewater treatment plant. The sampling area is approximately 1.2 m2.

[0039] Modification Plan: ① Install 24 automatic water samplers (4) with a capacity of 10L each, arranged in two rows of 12 samples each, next to the vortex sedimentation tank on the second-floor exterior wall of the fine-grit screen. ② Drill holes in the water grates of the overflow channel and use one submersible pump (3) to draw water and pump it into the samplers (4), which are 3m in diameter. 3 / h.

[0040] The automatic water sampler 4 is modified using DN150 UPVC pipe. A single pipe section with a height of approximately 32cm is cut from the cross-section. The upper section is sealed with a return pipe 1 that flows into the front end. The lower section is sealed and equipped with an electric ball valve 5. A manual ball valve is added to the side of the pipe for sampling and bottling. The submersible pump 3 and each sampler 4 are connected using DN20 UPVC pipe and fittings. Power connection, equipment support installation, chemical dosing pipe laying, and control box installation are carried out according to the actual site conditions.

[0041] Operating mode: Using a bottom-in, top-out method, sampler 4 continuously draws water 24 hours a day, averaging one sample per hour. Each time water is drawn from sampler 4, its electric ball valve opens, while the others close. When the electric ball valve of the next sampler 4 is fully open, the electric ball valve of the previous sampler 4 closes. When sampler 4 (number 24) is full, water is drawn from sampler 4 (number 1) again, and the water sample from the previous round flows back to the front end through the top inlet.

[0042] When the online system detects abnormal data or observes poor water intake, production personnel can determine the time period for sampler 4 to collect water for bottling and testing in the laboratory.
