How to dispose of waste liquid with online analytical instruments for COD/ammonia nitrogen/total phosphorus/total nitrogen
Thread Content
Dear experts: For the wastewater treatment system, online analysis instruments for COD, ammonia nitrogen, total phosphorus, and total nitrogen have been installed; these four instruments are placed in an analysis booth. I have a question: (1) Can the waste liquids from these four types of tables be discharged into one container? (2) How should the waste liquid from these four types of tables be disposed of? Must there be a dedicated section for recycling?
For the wastewater treatment system, online analysis instruments for COD/ammonia nitrogen/total phosphorus/total nitrogen have been installed; these four instruments are placed in an analysis booth. I have a question: (1) Can the waste liquids from these four types of tables be discharged into one container? The four types of waste liquids need to be collected separately. If you wish to discharge it into a waste liquid container, you must first ensure that no reactions or potential hazards will occur. (2) How should the waste liquid from these four types of tables be disposed of? Must there be a dedicated section for recycling? The treatment of these waste liquids is carried out by the using units themselves in accordance with the relevant regulations for the handling of hazardous waste.
There are certain standards for the disposal of waste liquids; if it’s not certain whether such liquids contain reactive or toxic substances, it’s best not to mix them together for collection. The material of the container should also be chosen based on the composition of the waste liquid; storage must take place in a dark place, away from heat sources. Labels indicating the type of waste and the date should be attached to facilitate centralized disposal. If a rapid water quality tester is available, a waste liquid collection container can be prepared in advance for on-site measurements. It seems that it is possible to entrust the task to a qualified organization.
