Research on Bioefficient Degradation Treatment Technology for Industrial Wastewater Pollution

为实现工业废水中环状有机化合物的生物高效降解处理,研究工业废水污染生物高效降解处理技术。该研究在厌氧、好氧条件下将环状有机化合物作为碳源实施驯化培养,以梯度形式增加底物浓度。在活性污泥中分离提纯多株特异性降解菌,在无机盐培养液中复配3株高效细菌,获得复合菌剂N12。在恒温水浴中运行生物反应器,在好氧与厌氧条件下驯化污泥,通过生物反应器生物高效降解处理废水。结果表明,随着HRT逐渐降低,萘、喹啉、吡啶的浓度大幅增加。随着DO逐渐增加,萘、喹啉、吡啶浓度大幅下降,该结果验证了文章技术的有效性。

In order to realize the bioefficient degradation of cyclic organic compounds in industrial wastewater,the bioefficient degradation treatment technology of industrial wastewater pollution was studied.Cyclic organic compounds were used as carbon sources for acclimation culture under anaerobic and aerobic conditions,and substrate concentration was increased in a gradient form.Multiple strains of specific degrading bacteria were isolated and purified from activated sludge,and 3 strains of efficient bacteria were mixed in inorganic salt medium to obtain complex bacterial agent N12.The sludge was acclimated under aerobic and anaerobic conditions by running a bioreactor in a constant temperature water bath.The results showed that the concentrations of naphthalene,quinoline and pyridine increased significantly with the gradual decrease of HRT.With the gradual increase of DO,the concentrations of naphthalene,quinoline and pyridine decreased significantly,which verified the effectiveness of the proposed technique.
