查询词典 water cycle

Seaweed extract-EClean was applied to treatment for eutrophication water. Quantative detection of nitrogen cycle bacteria showed that seaweed extract could improve the growth of ammonifying bacteria, nitrosobacteria and nitrobacteria in the treated water. There was also an increasing trend in the number of denitrifying bacteria in aerated treatment water, which showed that the seaweed extract could accelerate nitrogen cycle and the release of nitrogen from water.

利用国外引进的海藻提取物EClean制剂对富营养化水体进行处理试验，经过定量测定处理和对照水体中氮循环细菌数量的变化，得出EClean制剂能够促进水体的氨化细菌、亚硝化细菌、硝化细菌的生长，并维持了曝气条件下一定数量的反硝化细菌，通过此处理使得在同一反应器中、同一条件下完成硝化作用和反硝化作用成为可能，加速了水体的氮素循环，使水体总氮下降明显。

New type of water chemistry for utility drum boiler and its principle and characteristic Two kinds of water chemistry's main principle and characteristic are detailedly analyzed. Against the problem of high eroding speed, high Fe content in feed water and boiler water, high scaling speed, short chemical cleaning interval, needing poisonous chemical deoxidant, etc for drum boiler's deoxidization water chemistry and difficulty of using oxidation water chemistry, a new type of water chemistry is put forward on the basis of analyzing the characteristic of whole power station's water steam cycle system, principle of two kinds of water chemistry and their practical effect in every cycle stage. Considering two water chemistry's merit, a new water chemistry called Limited Oxidation Water Chemistry is put forward, which is a local slight oxidization no-deoxidant water chemistry. And the proposed method's principle, control parameter, applying condition, start-lay up and emergency measures are initially calculated and analyzed.
