Under normal circumstances, easily degradable organic matter is a significant pollutant in urban sewage, so many urban sewage treatment plants adopt aerobic biological treatment methods to deal with it. So how do you know the compliance rate of water quality? In fact, it’s quite simple. At this point, a water quality detector will be used for analysis.
If the proportion of wastewater in the sewage is high, the amount of refractory organic matter will be very high, and naturally the treatability of the sewage will deteriorate. At this time, it is necessary to consider adding anaerobic treatment to improve the treatability, or physicochemical treatment can also be used. Urban sewage is mainly divided into primary pretreatment, secondary main treatment, and tertiary treatment, which is relatively less used.
Among the wastewater discharged from factories, at least two-stage treatment should be adopted, as the sludge discharged from the secondary treatment is very likely to cause secondary pollution. Therefore, doing a good job in sludge treatment is particularly important. The treatment of urban sewage is actually a corresponding measure aimed at changing the specific situation of the sewage so that it does not cause harm to the environmental water body. (The treatment of urban sewage is divided into three levels: Primary treatment uses physical treatment methods to remove parasite eggs and insoluble pollutants from the sewage. Secondary treatment mainly utilizes biological treatment methods, which oxidize and degrade various organic substances in sewage into simple substances. Tertiary treatment involves biochemical, chemical precipitation and physicochemical methods, etc., to remove nitrogen, phosphorus, and some refractory organic and inorganic salts from wastewater.)
Staff can know the compliance rate of water quality through the water quality detector. Not only that, this instrument is also a device used to analyze the content of water quality components, mainly including online monitoring of drinking water, online monitoring of medical wastewater, process water monitoring, etc. There are also many monitoring items, such as: BOD, COD, total phosphorus, total nitrogen, ammonia nitrogen, heavy metals, biological toxicity, coliform bacteria, etc.
To protect the water environment well, it is essential to strengthen real-time monitoring of water quality in various fields such as sewage discharge. Only in this way can relevant departments promptly understand the water quality situation and then take appropriate measures.
