Coagulation/hydrolytic acidification/aerobic movable bed bio-film process was used for surfactant wastewater treatment. The running result shows that in the process,the removal rate of COD,BOD_5,SS,LAS,and TCC-TCS is averaged respectively at 92.7%,95.3%,91.3%,96.9%,and 100%,with effluent quality up to II-class criteria specified in Integrated Wastewater Discharge Standard (GB 8978—1996).
Results C4～C5,C5～C6 cervical vertebra always endure the maximum stress and movable degree, cervical vertebra unstability mainly occurs in C4～C5,C5～C6 ,and always represent in antexion and retroversio position.
The design concept and scheme of the movable test stand of overhauled diesel engines for DF 5, DF 5B , DF 7 and DF 7C locomotives, that is designed and built by Qilu Petrochemical Company Machinery Works are presented.
The condition of the steady-state regime of the absorption of gas molecules by the supercritical bubbles from solution with the movable bubble boundary was studied.
The problem of determining the velocity field excited by a sound wave impinging on a plate at rest is analyzed as an initial- and boundary-value problem with a movable boundary for the two-dimensional wave equation.
The article discusses the one-dimensional problem of the leaching of a soil with piecewise-homogeneous initial salinization under conditions of a movable wetting front.
Rarefied gas shear flow between two movable segments of parallel plates
The gas motion is simulated on the basis of a high-accuracy numerical method using adaptive movable networks.
