【摘要】：為比較小球藻(Chlorella Vulgaris)、四尾柵藻(Scenedesmus Quadricauda)和斜生柵藻(Scenedesmus Obliqnus)3株真菌微藻在不同濃度豬糞水沼液中的生長情況及氮磷去除率的差異,試驗選用豬糞水沼液,進行稀釋,得到1/1、1/2、1/4、1/8、1/16和1/32不同濃度的豬糞水沼液,高壓滅菌后,分別培養(yǎng)3株微藻。結(jié)果表明:3株微藻均能在糞水沼液中生長,而且能有效去除濃度為1/4、1/8、1/16和1/32的沼液中的氮磷;在濃度為1/4和1/8沼液中,小球藻相對生長速率最高,而在濃度為1/16和1/32的沼液中,四尾柵藻和斜生柵藻的生長速率優(yōu)于小球藻;在濃度為1/4、1/8、1/16和1/32的沼液中,斜生柵藻的總氮和氨態(tài)氮去除效果最佳;3株微藻在濃度為1/4和1/8的沼液中硝態(tài)氮增加,在1/16和1/32沼液硝態(tài)氮有所減少,其中四尾柵藻去除效果較好;四尾柵藻和斜生柵藻的總磷去除率基本相同,優(yōu)于小球藻。在本試驗條件下,小球藻和斜生柵藻可作為后期馴化的優(yōu)勢藻種。
[Abstract]:In order to compare the growth and nitrogen and phosphorus removal efficiency of Chlorella (Chlorella Vulgaris), (Scenedesmus Quadricauda) and (Scenedesmus Obliqnus) in different concentrations of porcine dung biogas, pig manure biogas liquid was used to dilute the microalgae. We got 1 / 1 / 1 / 2 / 1 / 4 / 8 / 8 / 1 / 16 and 1 / 32 of different concentrations of pig dung biogas liquid. After high pressure sterilization, we cultured three microalgae respectively. The results showed that all three strains of microalgae could grow in dung water biogas, and they could effectively remove nitrogen and phosphorus from biogas with a concentration of 1 / 4 / 8 / 8 / 16 and 1 / 32. In 1 / 4 and 1 / 8 biogas, Chlorella microalgae had the highest relative growth rate, but in the biogas with concentrations of 1 / 16 and 1 / 32, In the biogas with a concentration of 1 / 4 / 1 / 8 / 8 / 1 / 16 and 1 / 32, the removal efficiency of total nitrogen and ammonia nitrogen was the best among the three microalgae strains which increased nitrate nitrogen in the biogas with the concentration of 1 / 4 and 1 / 8. At 1 / 16 and 1 / 32, nitrate nitrogen in biogas liquid decreased, and the removal rate of total phosphorus was the same as that of Chlorella vulgaris, and the removal rate of total phosphorus was the same as that of Chlorella vulgaris, and the removal rate of total phosphorus was the same as that of Chlorella vulgaris. Under the experimental conditions, Chlorella vulgaris and S. obliquus can be used as dominant algae species for later domestication.
