摘要:
Wastewater, for example flue gas desulphurization blowdown water, containing soluble selenium is treated in a bioreactor. Microorganisms in the reactor reduce the selenium to elemental selenium, which is insoluble. The elemental selenium is discharged from the reactor in waste sludge also comprising biomass and other suspended solids. Non-microbial suspended solids are removed by way of acid dissolution followed by de-watering. The remaining sludge is burned at a temperature below the selenium oxidation temperature to remove biomass while leaving selenium particles behind.
摘要:
A process for removing microorganisms and/or precursors of disinfection by-products from a medium sought to be treated comprising treating the medium with one or more elements capable of forming an oxide, a hydroxide, and/or an oxyhydroxide through corrosion is disclosed. A system for effecting the removal or inactivation of microorganisms and/or disinfection by-product precursors is also contemplated.
摘要:
A process for measuring total microbiological content in an aqueous medium includes adding a fluorescent dye to the aqueous medium, measuring the fluorescent signal in the aqueous medium to obtain a baseline fluorescent signal, releasing intracellular content of the microbiological matter into the aqueous medium by lysing the microbiological matter, measuring the fluorescent signal in the aqueous medium with the released intracellular content of the microbiological matter to obtain a second fluorescent signal, subtracting the baseline signal from the second fluorescent signal to obtain a net fluorescent signal and equating the net fluorescent signal with a microbiological content. Methods for measuring biofilm and adjusting for background noise are also provided.

摘要:
The present invention discloses an input equipment with a sensed movement feedback, which comprises a pressure sensor pad having a through hole at the center, a rolling ball disposed in the through hole with part of the rolling ball exposed and protruded therefrom, and at least one driver contacting with the surface of the rolling ball. The sensor pad will produce a signal according to a pressing force exerting thereon and transmit the signal to a control circuit of the input equipment, enabling the control circuit to produce a rolling signal for activating the driver to move the rolling ball in a direction proportion to the pressing force. Thus, the user can sense the direction and speed of the cursor movement on the screen from sensing the rolling movement of the rolling ball.

This invention concerns a medical non-woven fabric containing inorganic oxides complex powder. The inorganic oxides complex powder consists of 80-95% (weight) of TiO.sub.2, 2-10% (weight) of Al.sub.2 O.sub.3 and 1-10% (weight) of SiO.sub.2. This medical non-woven fabric can improve microcirculation remarkably and has special effect of dephlogistication, detumescence and speeding up healing of wounds. Thus, it is suitable for supplementary treatment of tumefaction, surface wounds and fracture.

摘要:
The present invention provides a soil composition having improved water retention. The composition comprises soil particles and Bacillus subtilis UD1Q22. For example, the composition may comprise soil particles having a particle size no greater than 2 mm and at least 50% of the soil particles have a particle size in the range of 0.05-2 mm. A method for improving water retention of a soil composition is also provided. The method comprises applying an effective amount of Bacilus subtilis UD1022 to the soil composition to improve water retention of the soil composition.
