摘　　要：采用生活污水对高效藻类塘进行藻类培养驯化,在水深为0.5 m、流速为0.35 m/s以及气候适宜的条件下约4 d可培养成功。培养完成时优势藻为四尾栅藻(Scenedesmus quadricau-da),叶绿素a浓度为0.28 mg/L。通过分析塘内NO3--N和NO2--N浓度的变化规律发现,在藻、菌培养过程中存在藻类、亚硝酸菌、硝酸菌依次生长过程。高效藻类塘培养简单、启动快,有利于其在农村地区的推广应用。The algae in high rate algal pond （HRAP） was cultivated directly in domestic sewage under 0.5 m water deep, 0.35 m/s flow rate and good weather conditions. After about 4 days cuhivation, algae in HRAP is dominated by Scenedesmus quadricauda and the Chlorophyll a concentration is 0.28 mg/L. Through the NO3^-- N and NO2^- - N concentration change, it is concluded that there is a time sequence of the growth of algae, Nitrosornonas and Nitrobacter in cuhivation of algae-bacteria symbiosis system in HRAP. The algae cultivation in HRAP is simple and the startup is quick. Both are good for the application of HRAP in rural area.
