In the process of increasing the amount of COD will lead to the amount of BOD must also increase it? In the process of increasing the amount of COD will lead to the amount of BOD must also increase it? With the increasing awareness and awareness of environmental protection in our country, environmental law requirements are now more and more stringent. In addition, some of the indicators in the Environmental Protection Law have also raised the standard of handling standards. This is also a rather troubling issue for some factories and enterprises. The main reason for this is that the standards have been raised and some factories and enterprises are confronted with the problem of handling difficult targets. There are several indicators which are more important, such as: BOD, COD, phosphorus, color, etc., and in dealing with one of the more difficult things now. At present, the common use of physicochemical and biochemical treatment of domestic water treatment and the use of some water treatment chemicals in the treatment process will enhance the treatment effect. However, some agents themselves have a high COD and some COD will also be brought into the treatment process. So some people want to know in the water treatment process, add what medicine can increase the amount of COD in water, without increasing the amount of BOD it? Today, the filter source of water will be for everyone to explain the details are as follows. If you want to use pharmaceuticals in the laboratory configuration 1000ml (qualified) water samples, which should be added to the tap water or distilled water, BOD qualified, COD can achieve their desired value? In fact, in the process of water treatment, the dosage of COD increases after the water quality, the amount of BOD may not increase. Because BOD stands for Biochemical Oxygen Demand, the amount of oxygen needed to oxidize organic matter that is degraded by microorganisms. COD represents the amount of oxygen required to oxidize all reducing substances in water, including inorganic reducing substances and organic substances that can not be utilized by microorganisms. That COD contains BOD. There is no increase in both COD, BOD increased relationship. In addition, if it is desired to increase the COD without increasing the BOD, a reducing substance may be added to the wastewater, for example, reducing substances such as ferrous and pyrogallin. The easiest way: First, detect the COD value of a wastewater, diluted directly into the desired number can be.
