Treatment And Disposal

With rapid industrialization, continuous economic development, increasing population and living standards, the amount of general industrial solid waste generated in Kunming has increased continuously from 2001 to 2011. In 2013, the total general industrial solid waste generation was 33.19 million tons, deceased by 9.59% over 2011. The disposal and comprehensive use amount of general industrial solid waste in Kunming has increased dramatically from 2001 to 2013, and the disposal and comprehensive use rate of industrial solid waste increased fast from 64.39% in 2002 to 97.68% in 2013,but the comprehensive use rate of general industrial solid waste has not increased largely. Kunming’s general industrial solid waste treatment capacity has obvious difference from generation capacity, the produced industrial solid waste each year has the utilization of nearly 40%, with about 60% of the solid waste we cannot use. The disposal and comprehensive use rate of general industrial solid waste is different in different region of Kunming. Although the resource utilization of general industrial solid waste has made some progress in Kunming, the technical level is still very low compared with developed region, specially, the comprehensive utilization rate of phosphogypsum and tailings was not beyond 17% in 2013. Thereafter, much still can be done to improve the treatment and disposal of industrial solid waste in Kunming.

Solid Waste Pollution Control is one of the main special courses offered to students whose major is Environmental Engineering. It aims to let students know basic knowledge and control technologies of solid waste pollution, so that they can solve problems on solid waste treatment and disposal. With increasing generation of solid waste (municipal solid waste and industrial solid waste) in China, solid waste control becomes one of the focus environmental problems facing our country, which depends on efforts of environmental professionals. Solid waste control technology has seen a fast development in recent years. In order to keep up with solid waste control nowadays, it is necessary to develop this course to improve teaching effects. Based on analysis of the current conditions of this course, the paper offers a construction plan for the course in the following aspects: adjustment of the course teaching content, enrichment of teaching methods and teaching mode, preparation of test database and exercise database and suggestion of ways to increasing teaching effect of this course.

Selection Of

Selection of appropriate municipal solid waste (MSW) treatment and disposal technology is a complex multi-criteria process. This paper demonstrates the reliability of the use of multi-criteria decision-making (MCDM) framework for the purpose of selecting the best MSW treatment and disposal alternatives. In this paper, a modified fuzzy Delphi-AHP-TOPSIS methodology is developed for the selection of the most appropriate MSW treatment and disposal technology. The study provides a systematic three-stage methodology towards technology selection. In the first stage, experts' opinions were sought to select the relevant criteria and the fuzzy Delphi Method (FDM) was used to obtain the critical factors for the evaluation of alternatives. In the second stage, the criteria weights and their importance degree were calculated by using AHP. Finally, the TOPSIS technique was used for ranking the alternatives to determine the most appropriate option. The study identifies a minimal relevant set of evaluation criteria and appropriate technologies for the handling, treatment and disposal of MSW in a more economical and environmentally sustainable way. Thus, the developed MCDM framework enables decision-makers to make informed decisions and achieve optimal results. It helps the decision makers select the best possible technology in a scientific manner. To demonstrate the approach taken, a real case of Mumbai city is taken.
