Abstract

The invention discloses a method for optimizing a refinery wastewater biochemical processing unit based on software simulation, which comprises the following steps: a, investigating the refinery wastewater biochemical processing unit to determine the process flow; b, obtaining the sizes and process operation parameters of the structures of each biochemical section; c, obtaining historical inflow water quality data from a laboratory system of a water plant; d, supplementing to measure the inflow and outflow water quality parameters of the process over a period of time, and determining the characterization component parameters of the oily wastewater by component calculation; e, using mathematical software to build a model, inputting the sizes and the process operation parameters of the structures, the characterization component parameters of the oily wastewater, the historical inflow water quality and the water volume to carry out static and dynamic simulation; f, adjusting kinetic parameters and stoichiometric numbers to correct the model; g, carrying out a plurality of running state analyses and selecting an optimal operation plan. According to the method for optimizing a refinerywastewater biochemical processing unit based on software simulation in the invention, the effluent and energy consumption in different situations are analyzed through the corrected model; an optimal operation scheme is proposed; the unit processing efficiency is improved; and energy consumption is reduced.

Description

technical field [0001] The invention relates to an oily sewage treatment technology, in particular to an optimization method for a biochemical treatment unit of oil refinery sewage based on software simulation. Background technique [0002] The composition of wastewater generated by various units of crude oil refining in petrochemical enterprises is complex and difficult to treat. At the same time, the pollutant discharge standards of the petrochemical industry have been greatly improved. In the newly promulgated and implemented "Petroleum Refining Industry Pollutant Discharge Standards" (GB31570-2015), the emission limits for COD have been raised to 60mg / L, and ammonia nitrogen has been raised to 8.0mg / L, and newly increased the emission limit of total nitrogen to 40mg / L. And in areas where special protection measures are required, the emission limits of COD, ammonia nitrogen and total nitrogen are strictly controlled at 50mg / L, 5mg / L and 30mg / L. How to deal with the new...
