  • A new Organic Compound and phosphorus removal process with an anaerobic and two-stage alternation intermission aerobic conditions
    Journal of Jilin Institute of Chemical Technology, 2004
    Co-Authors: Cui Ming-can
    Abstract:

    A new reactor named CHBNR (Cui-Hong Biological Nutrients Removal Process) that could Remove phosphorus by an anaerobic and two-stage alternate intermittent aerobic process was developed based on studying mechanism of phosphorus removal. This process consists of anaerobic-anoxic-aerobic conditions, can Remove Organic Compound and phosphorus simultaneously. The removal rate of Organic Compound was over 92%, and the removal rate of total phosphorus T-P was 84%.

  • New anaerobic and two-stage alternation intermission aerobic process for nitrogen removal
    Journal of Jilin Institute of Chemical Technology, 2004
    Co-Authors: Cui Ming-can
    Abstract:

    In order to treat Organic Compounds and nitrogen in wastewater effectively,a new process named CHBNR that can Remove nitrogen by anaerobic and two-stage alternation intermission aeration is developed.This process consists of anaerobic,anoxic and aerobic zone in a reactor,and can treat Organic Compound effectively.During research and development,the removal rate of COD_(cr) and BOD_5 were over 92% all the time.The removal rates of total nitrogen T-N on the basis of different ratios of BOD_5/TKN are different.When the ratios of BOD_5 to TKN were 3.6～7.8 and about 2.1,the removal rates were 87%～89% and about 65% respectively.The removal rate of T-N trends decline with BOD_5/TKN decreasing.The CHBNR reactor has high efficiencies to Remove Organic Compound and nitrogen,and has good effect to precipitate sludge and Remove suspended solid (SS).

  • Three-dimensional titanium dioxide/graphene hybrids with improved performance for photocatalysis and energy storage.
    Journal of colloid and interface science, 2017
    Co-Authors: Lin Chen, Sudong Yang
    Abstract:

    Abstract A series of three-dimensional (3-D) TiO 2 /graphene (TiO 2 /GR) hybrids with different TiO 2 weight ratios were prepared using a self-assembly approach followed by the gaseous reduction in a hydrothermal system. The method was based on the electrostatic attraction between the positively charged titanium glycolate precursor and negatively charged graphene oxide in an aqueous medium without any surfactant or template. The structure, morphology, physical and optical properties of the as-synthesized hybrids were characterized, and the results showed that TiO 2 spheres were homogeneously confined within the 3-D networks of graphene, and acted as pillars to effectively separate the graphene sheets from each other. By optimizing the ratio of TiO 2 in the hybrids, the material was identified as an excellent photocatalyst to Remove Organic Compound in water with high degradation efficiency. Additionally, TiO 2 /GR hybrids delivered high specific capacity, enhanced rate capability and excellent cyclic stability when used as a freestanding electrode for lithium ion batteries.

  • Study on the Modeling of Anoxifier Process for Wastewater Treatment
    1996
    Co-Authors: Yang-kun Chun, Yong-su Choi, Youn-kyoo Choung
    Abstract:

    Anoxifier Process was invented to Remove Organic Compound as well as nitrogen. It was consisted of two parts; one part was aeration basin, the other was anoxifier which com bined anoxic basin and clarifier. Inclined plate divided anoxifier into clarifier and anoxic zone clearly, and it separated clear-layer from mixed liquid efficiently. Experimental and kinetic studies were carried out using this process. The results showed high removal rates for Organic Compound, nitrogen and suspended solid, in addition, running cost and establishing area could be saved. Therefore it was recognized that Anoxifier Process was recommendable for small wastewater treatment for Organic and nitrogen removal in rural areas close to the water resources.

  • Fabrication and Antibacterial Performance of Nano-silver-Doped Monoliths by the Sol-Gel Method
    South African journal of chemistry, 2013
    Co-Authors: Taymaz Tabari, Davood Beiknejad, Haman Tavakkoli, Mohammad Habibi Jouibari, Ramin Zafar Mehrabian, Mohammad Javad Chaichi
    Abstract:

    The Organic-inOrganic hybrids of glycine, tetraethylortho silicate (TEOS) and triethylphosphate (TEP) doped with silver ions were prepared by the sol-gel method. After moulding and heating at 600 °C to Remove Organic Compound, porous Ag/P 2 O 5- SiO 2  monoliths were obtained. Scanning electron microscopy (SEM), energy dispersive X-ray (EDX) spectrum, transmission electron microscopy (TEM), infrared spectroscopy (FT-IR) and scanning tunnelling microscopy (STM) were used to structurally study monoliths. Surface area, pore volume and swelling degree of the samples were adjusted with different contents of TEP in the starting composition. Ag ions were stably released into the water at 30 °C for 28 days. Antibacterial experimentation revealed that such materials, treated at 600 °C, could restrain Escherichia coli effectively.
