Well-kept heat: imported ammonia polyester bubbled to improve the heat preservation effect. In winter, overnight water is still hot. 保温好:进口聚氨脂发泡,提高保温效果,冬季隔夜水仍热。聚氨脂泡沫(塑料)
The operational results show only if controlling the work conditions of ammonia still and the pH of wastewater, ammonia still has high treatment effect on NH_3-N removal, the effluent quality reaches the secondary criteria specified in Integrated Wastewater Discharge Standard ( GB 8978-1996). 运行结果表明只要控制好蒸氨塔的操作条件和废水的pH值,对NH3-N可达到较高的去除效率,出水水质可以达到《污水综合排放标准》。
Although some of the loss of ammonia can be recycled time after time in the production of solid ammonium phosphate, the problem of ammonia loss is still not solved, furthermore the relevant equipments for recycling are required, which result in more investment and operating cost. 虽然在制固体磷铵生产过程中,损失的一部分氨可以多次回收利用,但仍然存在氨损失,且增加了相应的回收设备,其投入和操作成本也有所增加。
A method, which is used to measure the hydraulic level of ammonia still with an inside detector of the capacitance type, is introduced. 介绍了用内装电容式液位检测计测量氨蒸馏塔液位的方法。
Under condition of grey system, analyze the nutrition composition and tumour stomach degradation rate index for different Caragana treatments, establish treatment evaluation model, ammonia treatment is still the best of the comprehensive evaluation of all treatments. 在灰色系统下,对不同处理柠条营养成分、瘤胃降解率指标进行分析,建立处理效果评价模型,综合评价处理结果仍是氨化处理效果最好。
The Transform for Hydraulic Level Measuring System of Ammonia Still 氨蒸馏塔液位测量系统的改造
Application of Ammonia Still in Threonine Wastewater Treatment 蒸氨塔在苏氨酸废水处理中的应用
However, the impact of aeration on ammonia stripping of polluted river water is still a lack of in-depth study. 但是,曝气对污染河道水体氨挥发的影响尚缺乏系统深入的研究。
The removal of ammonia nitrogen in the artificial wastewater treatment system is still the concerned by the researchers. 尤其是在污水处理系统中,氨氮的有效去除一直是研究者们关注的问题。
Though ammonia and nitrite content were not high, but view from the special hydrogeological conditions as well as the nitrogen cycle, there is still a greater risk of contamination. 虽然该区氨氮和亚硝态氮含量并不高,但是从岩溶区特殊的水文地质条件以及氮循环的角度来看,还是存在较大的污染风险。
