　　What is the reason for the low COD removal rate in the aerobic pool for sewage treatment? 　　If the COD (chemical oxygen demand) removal rate in the aerobic pool is low, there may be several reasons: 　　1. High influent COD concentration: If the influent COD concentration exceeds the treatment capacity of the aerobic pool, the […]

　　What should I do if the effluent meets the standard but the sludge concentration rises very slowly? 　　If the effluent meets the standard but the sludge concentration rises very slowly, the following measures can be considered: 　　1. Increase the organic load: Increasing the organic load in the wastewater can stimulate the growth and reproduction of

　　The role of aerobic pools in sewage treatment 　　The aerobic pool is a key link in the sewage treatment system, and its main functions include the following aspects: 　　1. Organic matter degradation: There are a large number of aerobic microorganisms in the aerobic pool, which use oxygen to decompose organic matter into carbon dioxide and

　　Advantages of MBR membrane in pharmaceutical wastewater treatment 　　MBR membrane (membrane bioreactor) has the following advantages in pharmaceutical wastewater treatment: 　　1. Efficient solid-liquid separation: MBR membrane can efficiently filter and separate pollutants such as solid particles, microorganisms and colloid substances in wastewater, achieve effective solid-liquid separation, and thus produce clear and transparent treated water. 　　2.

　　What should I do if the phosphorus in the sewage treatment plant exceeds the standard? 　　If the phosphorus in the sewage treatment plant exceeds the standard, the following methods can be used to solve the problem: 　　1. Strengthen pre-treatment: Before entering the sewage treatment plant, source control can be strengthened to prevent excessive phosphorus from

　　How MBR membrane treats wastewater from meat processing plants 　　MBR membrane bioreactor is an efficient water treatment technology that can be used to treat wastewater from meat processing plants.
