What are the environmental protection analysis items in water quality testing?
Thread Content
I am working on the analytical procedures for water quality analysis, and I’m not sure what exactly the environmental testing items are Does it also include microbial analysis? It would be best if someone with experience in laboratory testing in factories could answer this.
1. Conduct an analysis based on the product structure of your factory. 2. Communicate and coordinate with the Environmental Protection Bureau; the specific analysis indicators must be finalized through these two steps, otherwise there will be too many such indicators
The scalper’s version is correct; it needs to be determined based on the specific characteristics of one’s workplace. I suggest you consult the \"GB 8978-1996 Comprehensive Wastewater Discharge Standards\" and compare it to see how many items are involved, before discussing matters with the environmental protection authorities.
The types and methods of water quality testing should be determined with reference to **wastewater discharge standards and local emission regulations. There are no specific regulations regarding the detection of microorganisms, but the levels of microorganisms can also be assessed through the testing of parameters such as TOC and BOD. Just conduct the tests in accordance with the requirements of the environmental protection agency and local authorities; the testing standards are clearly specified.
Suspended solids, mg/L; Total hardness, mmol/L; Total alkalinity, mmol/L; pH (25°C); Dissolved oxygen, mg/L
I’m not sure what the quality of your water is or what treatment processes are used; generally speaking, the following parameters are relevant for reference: pH value, suspended solids, dissolved oxygen, total arsenic, heavy metals, oils, bacteria, cyanides, COD, BOD5, total phosphorus, total fluorine, and so on. It should be chosen based on your original water quality and your treatment process. For example, COD analysis is generally not performed for inorganic water treatment. In other words, substances that were not present in the original water quality generally do not need to be dealt with after treatment.
I am currently working on the analysis of boiler circulating water. I have divided this task into routine water quality analysis and environmental protection-related analysis. There is a severe lack of information regarding the analysis of scale and corrosion products in industrial circulating water, and no national standards for this purpose can be found. Is there anyone among you who can help me out?
For water quality analysis in industrial circulating cooling water, the standard HG/T5609-2000 \"Methods for analyzing water quality in industrial circulating cooling water\" can be referred to. However, the carbon steel coupon corrosion test is generally conducted once a month to monitor the corrosion status of heat exchangers, and the amount of scale inhibitors and corrosion inhibitors to be added is determined based on the results of this monitoring.
Thank you to all my fellow sea travelers; the power of teamwork is truly remarkable – it allows us to overcome any problem.
Our company produces synthetic ammonia and urea, and the key pollutant in our wastewater is ammonia nitrogen; therefore, the environmental monitoring parameters for our wastewater include pH value, COD, BOD5, total phosphorus, and ammonia nitrogen.
I work in the coal chemical industry. The environmental parameters monitored in water-related projects include COD, BOD, suspended solids, ammonia nitrogen, nitrate nitrogen, nitrite nitrogen, pH, and oil. Regarding these projects, the relevant indicators are as **specified**
Generally, the following parameters are included: pH value, suspended solids, dissolved oxygen, total arsenic, heavy metals, petroleum compounds, TDS, ammonia nitrogen, phenols, COD, BOD5, total phosphorus, and so on.
