During growth process,microalgae is more demanding for temperature,and need to keep it in suitable ranges. The photobioreactor heating system based on Siemens S7-200 PLC was designed. The control system collects the temperature signal by temperature sensor,than put the signal into the PLC. PLC operates the signal,and output signal to control the operation of heating rods,achieved the microalgae automatic temperature control in winter. Results showed that the temperature overshoot does not exceed 1.5℃,the overshoot less than 7.5%,the static error less than ±0.5℃,when the temperature setting is 30℃. So the photobioreactor heating system has high control precision,good reliability. After application of the heating system,optical density of the microalgae increased from 0.29 to 1.28,COD removal rate reached 79.3%,TN removal rate reached 65.07%,TP removal rate reached 83.03%. Therefore,photobioreactor heating system can be used to cultivate the microalgae, and the microalgae can treat the waste water efficiently,so it has good application prospects.

The chemical composition of waste oil biodiesel ( WME) was analyzed by GC -MS,and the low-temperature fluidity of WME was studied by low temperature differential scanning calorimetry and cold filter plugging point ( CFPP) tester. Three approaches for reducing CFPP of WME were investigated including crystallization fractionation, blending with -10PD and adding cold flow improvers ( Flow Fit, Flow Fit K and T818 ) . The results showed that WME was mainly composed of fatty acid methyl esters with 14-22 of even number carbon atoms, in which the contents of saturated and unsaturated fatty acid methyl esters were 31. 04% and 64. 51%, respectively. The initial crystallization precipitation tempera-ture and CFPP of WME were 1. 1℃ and 3℃, respectively. Blending with-10PD, the CFPP of B20-B30 decreased to -12℃. The CFPPs of WME, B80, B60, B40, B20, B10 and B5 added with 0. 1%of Flow Fit K decreased from 3 , -1 , -5 , -9 , -12 , -9 ,-8℃ to -1 , -4 , -10 , -17 , -24 ,-24,-26℃, respectively.
