Description
According to the task, the efficiency of the treatment plant is 9039.32 m ³/day. With maximum hourly flow rate qmax = 784.48 m3/h. Water disposal rate for the first area q1 = 195 l/day and the second area q2 = 250 l/day. Waste water consumption from the industrial enterprise is 4711.87 m3/day. The population is 17715 people. The reservoir belongs to category I. In this course design, it is necessary: to calculate and design sewage treatment facilities, determine the necessary degree of wastewater treatment, select the composition and type of treatment facilities, calculate the wastewater treatment plant, develop the general plan of the treatment plant, perform hydraulic calculation of communications and compile profiles on the movement of water and precipitation.
