Pickling wastewater with high organic matter, high salt content (about 7), biochemical characteristics at around 04, the biggest difficulty lies in the establishment of the high salt treatment of biological system normal biological treatment and biochemical poor biochemical effects; the test mainly aims at the hydrolysis acidification process, the effect of culture method the effect of high salt biological systems and temperature on high salt biological systems using phase, test results show that: in the middle temperature (28 ± 2 ℃) using stage culture method can establish the high salt biological systems are good, the salt content in the pickling waste water treatment waste water of about 55, BC increased from 04 about 06, the removal rate of COD is 2381, the microbial activity in 2811mgL temperature, volatile fat

Pickling waste water with high organic matter, high salt content (7%), but the characteristics of biochemical resistance around 0.4, the biggest difficulty of its treatment is poor biochemical affects normal biological methods of treatment and biochemical period of the establishment of a high salt biological systems; This experiment mainly aimed at the hydrolysis acidification process, examines the stage culture method is used to establish high salt biological systems and the effect of temperature on the high salt effects of biological systems, the results show that under the temperature (28 plus or minus 2 ℃) in the stage of culture method can be used to establish a good high salt, biological systems for wastewater treatment effect of salt content at 5.5% is good, the wastewater B/C increased from 0.4 to 0.6 or so, COD removal rate was 23.81%, the temperature of the microbial activity in 28.11 mg/L, volatile fatty acid (VFA) for 34 tendency for L.
