沉积循环
The tectonic-hydrogeologic evolution of the basin includes the following three stages: ( 1) the open cycle of down-faulted basin formation; ( 2) the close cycle sedimentation and diagenesis, and ( 3) the run-off cycle of epigenetic reworking.
盆地构造水文地质演化经历了断陷成盆期的开放旋回、沉积与成岩作用期的封闭旋回和后生改造期的径流旋回等3个阶段。
SBR has such characteristics as great shock-load resistance, flexible operational cycle, highly auto-control, secondary sedimentation tank exception and sludge bulking restraint.
SBR抗冲击负荷能力较强,运行周期可灵活调整,自控程度高,无需另设二沉池,并可有效抑制污泥膨胀。
