The experimental results show that it could meet discharge standard at 20\|30 min of HRT (hydraulic retention time) for low COD concentration and 60\|120 min of HRT for medium and high COD concentration. The maximal COD volume loading and COD sludge loading of 27 kg\5m -3 \5d -1 and 5 kg/d per kg MLSS were acheived respectively, that were 10\|20 times higher than those of traditional wastewater treatment processes. The BOD 5 removal efficiency was more than 90% and NH + 4 —N more than 85%. The study on the activity showed that the oxygen consumption rate of the activated sludge in the JIBR was 39.13 mg\5L -1 \5h -1 , which was 1.7 times higher than that of the SBR(Sequencing Batch Reactor) and the dominant bacteria in jet inner\|loop bioreactor was Pseudomonas species.展开更多

As an important part of the junior high school teaching system, this point is no exception. Based on this, how to realize the "burden reduction and increase efficiency" of junior high school Chinese teaching has become an urgent problem for the majority of teaching workers at the present stage. The following closely follow the above topics, first analyze the significance of "reducing burden and increasing efficiency" of junior high school Chinese teaching under the new curriculum reform, and then explore the strategy of "reducing burden and increasing efficiency" of junior high school Chinese teaching, hoping to provide favorable reference.展开更多

Methods: from January 20 to January 21, 92 cases were included in our hospital for digestive endoscopy diagnosis and treatment. They were divided into two groups according to the nursing mode. The number of cases included was 46. According to the nursing means, it is named as routine nursing group and comfort nursing group. In the nursing process, the nursing scheme adopted by the routine nursing group for patients is traditional routine nursing, and the nursing scheme adopted by the comfort nursing group for patients is comfort nursing intervention. Summarize and explore the effect of nursing implementation. Results: (1) after comparison, the score of comfort nursing in the routine group was lower and that in the comfort nursing group was higher. There was significant difference between the two groups (P < 0.05). (2) By comparison, the incidence of adverse reactions was higher in the routine nursing group and lower in the comfortable nursing group (P < 0.05). (3) By comparison, the recovery time of gastrointestinal function was longer in the routine nursing group and shorter in the comfort nursing group (P < 0.05). Conclusion: in the process of gastrointestinal endoscopy diagnosis and treatment, combined with comfort nursing intervention can improve the quality of nursing. This scheme is worthy of clinical application and popularization.展开更多
