The quality of hair dyeing sewage are closely related to the species, currently on the market a wide variety of hair dyes, but the main raw material substantially the same, mainly containing aniline, p-phenylenediamine (C6H8N2), m(p) -hydroquinone (C6H6O2), o-(m, p)-aminophenol (C6H7NO), etc.aniline, phenol organics and thioglycolic acid (C2H4O2S), Cetearyl Alcohol, Oleth-30, α-iso-methylionone, polydimethylsiloxane and other organic compounds [1-3].
Aniline is an important raw material of dye industry, such substances toxic, carcinogenic effects are obvious, because of the environment and human health impacts greatly, it was first included in the class of fourteen priority pollutants blacklist.
Materials and methods Water Quality.
(2) Although the hair dyeing sewage and mixed sewage phosphorus is relatively high, but hair dye containing cyclic organic material, of biological phosphorus removal is not adversely affected, instead, it is higher than domestic sewage phosphorus removal; and hair dyeing sewage on ammonia removal has little effect, through the nitrification of nitrite bacteria and nitrate bacteria in the reactor hair dyeing sewage ammonia can be removed

When the tool is loaded, the clamping section of the shank is first heated, the metal material is thermally expanded, and the size of the clamping hole becomes larger.
Cooling, the tool is firmly clamped by the contraction force of the material of the shank; the thermal cycle of the unloading process is the same as the thermal cycle of the tool.

Therefore, the importance of reliable metrology at an early stage of device making is, not only critical to improve yield prediction accuracy, but also to steer material to the appropriate application, and close feedback loops, ensuring improvement in the subsequent material growth and manufacturing.
PL can be associated with electrical properties, as the excitation and recombination in effect is locally more likely to happen due to changes of the energy states, a more observable phenomena in mono-crystalline material since the event is isolated to crystal abnormalities (defects) but less relatable with parametric failures than localized reduced depletion voltage, which is observed at defective sites by QUAD.

Moreover, prior to the development of modern theoretical corpus of mechanics of solids and materials, physical scaled models used to be the only tool aimed at the estimation of reliability of solutions within a framework of “trial and error” methodology.
This could likely constitute an evidence of plastic incursion, although the yielding resistance of the material is not known.

The samples of industrial alkali lignin made by spray-drying black liquor from alkaline pulping of wheat straw were provided from Shanghai Jinshan New Building Material Co., Ltd.
Considering brown and light brown liquid products with oxygen supplies of 100% at a lower temperature (i. e. 270 oC), liquid products took on dark brown when oxygen supplies were lower than 100% at 300 oC, which probably meant that the materials had not been oxidized enough and there stockpiled quantities of immediate brown products such as the quinines (reaction pathways discussed hereinafter).
The amides were probably produced from oxidation of the extractives of nuclear materials or/and proteins in cell wall of the plants used for pulping, and the cyclopentenones from hemicelluloses and fine celluloses dissolved during alkaline pulping; the aldehydes and acetones were usually the pyrolytic/hydrolytic products of lignin and its immediate oxidized products.
