摘要
主要研究了给水处理构筑物中氮、磷营养、温度、pH等环境因素对藻类生长的影响,结果表明:氮、磷处于富营养化时,藻类生长快速,磷和氮分别限制时,藻类生长缓慢;藻类生长适宜温度为25～32℃,pH为6.5～7.5;光照对藻类的生长影响最大,光强减弱,藻类增长速度减小;振荡的时间和速度均影响藻类的生长。合理控制光照、pH、水温和振荡等条件可有效地抑制藻类生长。因此,采取减少藻源、适当提高pH值、搭建遮光设施、减小光照强度等措施可抑制藻类生长。
In the building of water supply,the s everal environmental factors affecting the algous growth,such as the nitrogen and phosphor,the temperature,the pH value,et.al were studied,it shows that when the nitrogen a nd phosphor are in richer nourishment,the algae grow quickly;the suitable temperature is between 25℃and 32℃;the pH value is between 6.5and 7.5,th e sunshine is the most great factors t o the algous growth;the time and velocity of surge affect the algous g rowth .The optimized condition affe cting the algous growth can be contro lled effectively.Algous growth can be co ntrolled by decreasing original alg ae,suitably increasing pH value,bu ilding establishment for blocking sunligh t.
