In recent years, with the improvement of living standards, people's demand for aquatic products continues to increase, heavy industry develops rapidly, and the treatment of heavy industry polluted wastewater has become the focus of attention. The purpose of this work is to study the purification of heavy industrial polluted wastewater by high-energy microalgae based on photobioreactors. The algal-bacterial symbiotic system studies the pollution removal rule and the effect of microalgae cultivation. Light characteristics and average light intensity in algal liquid, degree of mixing of liquid in the reactor, and the effect of CO2 on microalgal growth and medium pH. The removal results of inorganic nitrogen continuous treatment showed that in the continuous treatment process of 6d, after treatment by the reactor, the concentration difference of NH4+-N in the effluent was controlled in the range of 0.39~0.51 mg-L-1, the average removal rate is 97.1%, the pH value remains stable, and the purification effect of heavy industry polluted wastewater is ideal.
