Experimental study of garden waste and vegetable waste co-composting

Wenxiong Huang Dandan Huang Ran Yin Zhiyun Qu Yuan Song

Three kinds of aeration modes were carried out in windrow, to investigate the effects of aeration modes on the co-composting of garden waste and vegetable waste. The composting parameters such as temperature, oxygen concentration, volatile organic compounds, ratio of organic carbon to total nitrogen (C/N) and oxygen concentration showed that oxygen-dependent and intermittent ventilation composting products were stabilized after 42 days of co-composting. And the days of temperature above 55□ were 7d, 9d, respectively, meeting the requirements to kill pathogens. However, the index results of natural ventilation showed that the compost is not fully maturity. This shows that co-composting of garden waste and vegetable waste by aerobic composting of ventilation control in windrow can get quality compost by optimizing composting process during 42 days. Composting can decrease non-point resource of organic solid waste by recycling nutrition to soil and improve fertility of soil.

Research on the generation amount and processing mode of rural domestic waste in eastern Shandong

International Conference on Electrical and Control Engineering (2011)

Yuan Song Zhiyun Qu Wenxiong Huang Haiyun Xu Ran Yin

To explore the feasible management mode of rural domestic waste in eastern Shandong, based on the model domestic waste collection system, this paper takes research on the generation status of rural domestic waste in Shangbo Village, Yifengdian Town, Jimo City, analyzes the processing technique combined with possible waste dissolving ways in that area , and gives some proposals on management. The result shows that the generation amount of domestic waste in research area is 0.48kg/ (person-d), of which organic waste dominates 63 percent. With different attributes, rural domestic waste should be disposed by different source separations, therefore to reduce the collection and transportation quantity, and to achieve the waste reduction and resource processing.

Research on feasibility of RDF producing by source separation of rural solid waste — Taking eastern Shandong district for example

International Conference on Electrical and Control Engineering (2011)

Yuan Song Zhiyun Qu Wenxiong Huang Ran Yin Dandan Huang

This paper takes analysis on the components, water ratio, calorific value and other parameters of rural solid waste of eastern Shandong district by source separation, and explores the feasibility of refuse derived fuel(RDF) production after separated collection of solid waste. The research shows that within all the rural solid waste of eastern Shandong district, organic component is the largest one with percentage from 60% to 80%; inert refuse takes the second place from about 10% to 30%; whereas recoverable waste owns the smallest share only from 10% to 20%. Among all the solid waste, moisture content of organic refuse takes over 65% of all, which fundamentally lead solid waste to low calorific value in China. According to low calorific value analysis of different source separated components, recoverable waste is found most appropriate to be RDF raw materials with low-calorific value over 10000KJ/kg, and is effective for waste reduction and resource harmlessness of rural solid waste.

Discussion on the classification and processing mode of municipal solid waste

International Conference on Electrical and Control Engineering (2011)

Yuan Song Zhiyun Qu Wenxiong Huang Haiyun Xu Ran Yin

This paper summarizes present status of municipal solid waste (hereinafter referred to as MSW) through literature review, takes in-depth analysis on the classification of MSW in different countries and regions, and explores influencing factors of MSW classification methods. Based on above, this paper makes pointed recommendations on the processing technical route and management during implementation of MSW, to achieve the waste reduction and resource processing at present stage.

Risk management in BOT projects of WTE plant

Wenxiong Huang XU Wen-long Zhiyun Qu Yun Song

This paper gives a systemic and comprehensive risk analysis of WTE plant BOT projects. The risk change curves of government and project owner in different periods are analyzed. Twelve key risks which impact on WTE plant BOT projects are identified. And all these risks are classified by government, project companies or allocated between the two parts according to risk management principle. At last, the strategies of risks allocation and precaution are presented for this kind of BOT projects, to provide a risk management framework for project participants, especially for local government.

Influence of turning and air-flow temperature on aerobic bio-drying of MSW

International Conference on Electrical and Control Engineering (2011)

Dandan Huang Wenxiong Huang Ran Yin Zhiyun Qu Yuan Song

Taking high moisture-content MSW collected in a mixing way as object, influences of turning and air-flow temperature on bio-drying process were studied using a self-designed experimental equipment. The results showed that turning could further improve bio-drying effect better with intermittent ventilation. When the air-flow temperature is 40°C, the moisture-content of materials could be decreased from 61.6% to 23.7%, after 18d of bio-drying process. And the heat value advanced 198.2%.

Research on food waste source classification recycling

International Conference on Electrical and Control Engineering (2011)

Ran Yin Wenxiong Huang Zhiyun Qu Ruifeng Guo Dandan Huang

Restaurant food waste has been changed from solid waste into resources. As the existing disposal of restaurant food waste are lack of uniform quality standards, food waste collected from the restaurants which mixing with impurity such as paper and plastic may cause food waste handling companies cannot run continuously and equipment failures, holding back the food kitchen waste resource utilization industry's sustainable development. This situation could be changed from following aspects, such as policy, management, economics, and the development of source classification of food waste treatment standards. Different productions for recycling food waste requires different quality of food waste, the corresponding processing cost is also different. Recycling food waste can be divided into three grades according to their quality, different grades of food waste recycling for different recycling prices. And the classification also helps improves the quality of food waste.
