Capsule production wastewater is a high-concentration organic wastewater, which contains a large amount of collagen and organic matter, etc. Traditional treatment methods often have problems such as poor treatment effect and sludge production. The purpose of this study was to explore the feasibility and effect of the two-stage A O+MBR combined process for the treatment of capsule production wastewater.
The two-stage AO+MBR combination process is mainly composed of two aerobic anaerobic (AO) biochemical cells and an MBR membrane reaction cell. Among them, the first-stage AO biochemical tank is responsible for the initial removal of BOD5 and nutrients such as nitrogen and phosphorus in the wastewater, and the second-stage AO biochemical tank further removes organic matter such as BOD5 and COD. The membrane reactor uses MBR membrane technology to further treat the treated wastewater to remove the remaining suspended solids and collagen substances in the wastewater, so that the effluent can meet important water quality standards.
The experimental results show that the two-stage A O+MBR combined process has a good effect on the treatment of capsule production wastewater. First, under aerobic conditions, the AO process uses microorganisms to decompose and oxidize the organic matter in the wastewater. Secondly, the combination of AO biochemical tank and MBR membrane reaction tank can effectively remove suspended solids and collagen in wastewater, and improve the transparency and hygiene index of effluent. In addition, MBR membranes can also prevent the loss of microorganisms, enhance the microbial degradation ability of wastewater, and allow the treated water to be better recycled.
In addition to the advantages in terms of treatment results, the two-stage A O+MBR combination process has other characteristics. First of all, the process is able to adapt to the special properties of the capsule production wastewater, such as high concentrations of collagen and organic matter. Secondly, the process produces less sludge and consumes less energy, and puts less pressure on the environment. In addition, the two-stage A O+MBR combination process also has high operational stability and reliability, stable wastewater treatment effect and low operational requirements.
In summary, the two-stage A O+MBR combination process is an efficient and feasible method for treating wastewater from capsule production. This process can efficiently degrade organic matter and collagen and other substances in wastewater, improve the purification effect of wastewater, and realize resource utilization. Future research also needs to further consider the optimization of operating parameters and the economics of the process to improve its feasibility and sustainability in practical applications.
