The invention discloses a water quality total nitrogen on-line automatic monitoring device. The automatic monitoring device comprises a sampling system (1), a reaction system (2) and a detection system (3) which are orderly connected through pipelines. The automatic monitoring device is characterized by also comprising a PLC control system (4), wherein the PLC control system (4) controls the sampling system (1) to sample water, the sampled water reacts sufficiently in the reaction system (2), and the detection system (3) detects reactant liquid to realize automatic monitoring. Compared with the like products, the device has the advantages of lower failure rate, less maintenance, lower reagent consumption and higher performance price ratio and accuracy.
Description
technical field [0001] The invention belongs to the technical field of water quality monitoring, and in particular relates to an online automatic monitoring device for water quality total nitrogen. Background technique [0002] In the prior art, my country's previous water pollutant discharge standards only stipulated the discharge limit of ammonia nitrogen, but did not stipulate the discharge limit of total nitrogen. Therefore, enterprises only pay attention to the removal of ammonia and helium in wastewater treatment. Total nitrogen includes organic nitrogen, nitrite nitrogen and nitrate nitrogen. The control of ammonia nitrogen in sewage by enterprises only changes ammonia nitrogen into nitrate nitrogen. Experts pointed out that only when ammonia nitrogen and total nitrogen are controlled at the same time, and nitrate nitrogen is converted into non-polluting nitrogen, can the harmless treatment of ammonia nitrogen wastewater be finally completed. [0003] The few forms ...
