The present invention relates to a glass noodles wastewater treatment process based on microalgae, belonging to the technical field of microbial wastewater treatment. Chlorella sorokiniana NZ1 and Monoraphidium sp. NZ4 are selected. An analysis of experiment results shows that when Chlorella sorokiniana NZ1 and Monoraphidium sp. NZ4 are subjected to mixed culturing, the biomass of both in the wastewater reaches the highest level. At the same time, the removal rates of water quality indicators also exhibit the most significant improvement; specifically, the removal rates of COD, TN, ammonia nitrogen, and TP can respectively reach 83.4%, 91.19%, 81.51%, and 78.71%. Thus, it can be concluded that subjecting the algal strains NZ1 and NZ4 to mixed culturing is the most effective glass noodles wastewater treatment method.
