The Treatment Of Oil-Fat Industry Wastewater

To the wastewater treatment project in Mosslom people daily expenses and chemistry plant in changzhi province,the thesis analysed the pioduce and quality and the ingredient of polluting material of oil-fat wastewater,meanwhile,integrating engineering example, a set of process route line about wastewater treatment was selected,which was dependable in the technology and reasonable in the process. The more detailed theory research was made to the main link of SBR process in biochemical section about wastewater treatment.The main research achievements were as follows:1.The produce wastewater was main produced from the alkline cleaning-and-refming and soap chemical engineering segment,the wastewater included a large quantity of organic matter such as suspended, soluble animal oil,fatty acid,glycerin etc,which had many peculiarities such as little water quantity,high organic matter and better biochemical bility.2.The analysis and study were made to the oil-fat wastewater treatment engineering example which had been put into effected.3.The reasonable wastewater treatment process which was combined by physical separating such as oil-fat captured reactor and air-floating and biological process(SBR) degradation.4.The reasonable calculated method was refered to the main disposal buildingsand equipments.5.The rearch of subject made a better theory cushion to the design of wastewater treatment construction diagram in Mosslom people daily expenses and chemistry plant in changzhi province.
