Pickled mustard tuber, a worldwide condiment, is increasing at a fast growth rate. Its production generates a considerable amount of hypersaline wastewater containing NaCl of 7 wt.%, COD of 30,000 mg L−1, NH3-N of 400 mg L−1, and TP of 300 mg L−1. Pickled mustard tuber wastewater (PMTW) has severe effects on crops, deterioration of water quality, soil infertility and ecological systems. Due to the technic difficulties and insufficient support from the local governments; however, PMTW has not yet been widely investigated and well summarized. Therefore, this manuscript reviewed the relatively latest advances in PMTW. Physicochemical and biological hybrid processes mainly treat PMTW and the corresponding cost is 6.00 US dollars per ton. In the context of double carbon capture capacity in China and the development of the pickled mustard industry, PMTW sauce and sustainable reuse such as nutrient recovery, acid and alkaline regeneration and renewable energy may be bright prospects.
Ergonomic evaluation of Industrial Design products is inevitably requested because of the extensive use of ergonomics in industrial design. The appraise frame of the system and the mathematics model are built by the divide layers of fuzzy appraisal algorithms. The method of investigating and recognizing is used to attain the membership function and weight of each factor vector. The first class of factor vector including gauge shape, alignment method and so on is built, according to man-machine interactive access of fascia; then the second class of factor vector including appearance dial, character list, point needle, the color matches etc. Microsoft Visual C++6.0 is used to evaluate the system of the car instrument panel design.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
