For achieving the above object, the method for processing high density poisonous organic wastewater provided by the invention, key step is as follows:
1, Wastewater Pretreatment: according to the water quality characteristic of waste water, pollutent by interfere with subsequent biological treatments such as the suspended particulate in methods such as precipitation, oil removal, air supporting, cooling, neutralization, the interpolation nutritive salt removal waste water, oils makes temperature, pH and the nutritional condition of waste water be fit to subsequent biological treatment simultaneously;
2, pretreated waste water enters buffer-type circulation carrier organism bed and handles, and realizes that the high density toxic organic compound efficiently removes.Buffer-type circulation carrier organism bed is characterised in that:
A. reactor is divided into some lattices, is series system between each lattice, and according to wastewater characteristics and processing requirements, lattice quantity is that 3～10 lattice do not wait.The useful volume of the 1st lattice is 1～2 times of other lattice useful volumes.According to the wastewater treatment requirement, each lattice can adopt anaerobism, anoxic respectively, hold concurrently oxygen and aerobic operation scheme, by form function and the different microbial population of characteristic in different lattices, realizes the efficient degradation of toxic organic compound; When wastewater treatment has the denitrogenation requirement, can adopt the segmental influent mode, to make full use of the own carbon source in the waste water, reduce mixed-liquor return, cut down the consumption of energy.Last lattice are precipitation unit, are back to last lattice through precipitating spissated suspended sludge under action of gravity, thereby improve the contaminant removal capacity of reactor end.
