The Application of Organica Ecological Technology in Residential Sewage Treatment

Water is the basis in ecological residential area. It is very important to recycle the water resource in the designing and planning of the ecological residential quarter due to the critical way to realize the wastewater resource utilization. In this paper, a new technology of wastewater treatment is introduced, which is ORGANICA ecotechnology. We integrate the traditional wastewater treatment technology and modern ecological engineering technology together and apply the integrated technology in the treatment of domestic sewage. The treated water can be reused for landscape and greening, which can beautify the residential area and recycle wastewater.

锌及锌源在肉鸡应用的研究进展

锌是动物营养界已经确定的畜禽所必需的一种重要微量元素。自1934年Todd首先证明锌是动物营养所必需的元素以来，世界各国学者对锌做了大量的研究工作，并且在锌的生理功能，营养作用，生化代谢等方面都做了较深入的研究，同时随着分子生物技术的水平的发展，也已有人证明锌在凋亡调控基因bel-2／bax中起重要作用（单延春等，2004）。然而随着近日高锌饲粮在生产中的应用，其对环境的污染也越来越受到人们的重视。
