| titleOfInvention | A sampling system for water quality COD/ammonia nitrogen analyzer |
| abstract | The utility model relates to the technical field of water quality sampling, and discloses a sampling system for a water quality COD/ammonia nitrogen analyzer, comprising a secondary treatment system and a primary treatment system, wherein the primary treatment system is connected by a seventh connecting pipe and a sixth connecting pipe A third pipe sleeve is installed on the outside of the seventh connecting pipe, a first ball valve is installed between the seventh connecting pipe and the sixth connecting pipe, and the outside of the sixth connecting pipe is A second ball valve, a membrane filter, and a pressure gauge are installed, and the second ball valve, the membrane filter, and the pressure gauge are sealed and fixed with the sixth connecting pipe, and the outside of the fifth connecting pipe is installed with a second pipe sleeve and a sixth connecting pipe. Three ball valve. The utility model adopts a two-stage pretreatment mode to provide the water sample to be tested for the instrument, and the sampler can effectively filter impurities without affecting the value of COD/ammonia nitrogen in the water sample. |
