Embodiment 1

[0115] In this example, the second phase UNITANK process of Guangzhou Liede Sewage Treatment Plant is selected. Each treatment unit is composed of three reaction (sedimentation) tanks with the same effective volume, and the effective volume of a single tank is 4547m 3 , the average treated water volume is 1365m 3 / h, and the hydraulic retention time (including sedimentation time) is about 10 hours. Now the process is running stably, and various water quality indicators are well represented. On the one hand, this process is selected to verify the reliability of the calculation effect of this system, and on the other hand, this simulation calculation is used to illustrate the use process of this system. attached figure 1 It is a schematic diagram of the design principle of the present invention, with figure 2 It is a block diagram of the simulation operation flow chart of the present invention, and the specific operations are as follows:

Abstract

The invention relates to a technology for processing active sludge of urban sewage, wherein a computer and corresponding operation system are used as a platform for executing a simulation software for forecasting efficiency of active sludge treatment and analyzing working conditions based on various technological parameters, the simulation software comprises a mode selection module, a basic data module, a computational condition module, a computation module, a result output module and an auxiliary function module.

Description

technical field [0001] The invention relates to the treatment technology of urban sewage activated sludge, specifically a calculation and simulation method for analyzing the efficiency of the activated sludge treatment process, and studying the parameters such as water quality change, volume change and sludge discharge amount in the process. Background technique [0002] my country's economy has experienced rapid development, and the economic level has been greatly improved, but it has also brought about a severe situation of environmental pollution. my country's sewage treatment engineering technology is relatively backward. How to realize the transition from extensive to precise in the design and operation of sewage treatment projects, so as to save investment, reduce operating costs, and improve effluent water quality is a practical problem that needs to be solved urgently. At present, the activated sludge method is the main treatment method adopted by most urban sewage t...
