Poyang Lake is under the potential threaten from water eutrophication. The implementation of pollution-purifying agricultural industrialization in the Poyang Lake area is an important strategy for controlling the non-point source pollution and achieving economic transformation in the area. In this article, the characteristics of pollution-purifying agriculture and the advantages for its industrialization in the Poyang Lake is discussed. The suitable patterns for the implementation of purifying-agricultural industrialization in Poyang Lake are also proposed.

The water quality monitoring revealed that the water quality in Poyang Lake is increasely degenerating in the past several years and the deterioration reasons were analyzed. The increasingly serious water pollution indicated that there were inherent drawbacks in current environmental management system of China. Therefore, the typical models of water pollution prevention and control in developed countries and China were researched. The explorations of water pollution prevention and control based on ecosystem management for Poyang Lake were reviewed, especially the practice of Mountain-River-Lake (MRL) Program in Poyang Lake Basin. At last, the challenges of water pollution prevention and control in Poyang Lake Basin was put forword such as law and policy, organization structure, participation mechanism. The researches indicated that the multiplicity and complexity of nature, humanities, society and economy in Poyang Lake determined its importance and necessity to implement ecosystem-based water environment management. In the future construction of water pollution prevention model based on integrated ecosystem management is an inevitable trend for Poyang Lake basin.

Various mechanical forces are used to promote the waste thermosetting phenol resin to produce the physical decomposition process. The molecular structure and physicochemical properties change, thus it obtains the reversible thermos plasticity and restore the processing performance. The paper proposes the regeneration principle based on physical methods, and smashing and regeneration experiments have been carried out. The optimized design for important factors of rotational speed, crushing time, feed, feed size and other parameters which impact crushing and regenerating effects has been carried out after experiments. Multivariate quadratic simulation equations are established and the order of significantly affecting the regeneration is determined.

Based on software GaBi4.3, life cycle assessment method is used to analyze the abiotic depletion, energy consumption and environmental emissions of recycling process of 1kg waste thermosetting phenolic laminated plastic. This paper also takes advantage of CML2001 provided by GaBi to assess the environmental impacts through the recycling process. The result shows that the rank of environmental impact is: Regeneration> Molding > Crush; the main environmental impacts are global warming potential, acidification potential and eutrophication potential.

Pulverizing the waste thermosetting phenol-formaldehyde resins by the self-developed machine which is used to recycle thermosetting plastics, studying the variable laws of fractions of different particle changing with the pulverization time, and establishing a pulverizing dynamic model by regression analysis. The results show that the particle distribution parameters b and m are not constants but the functions of pulverization time; the established equation of regression dynamic is high accurate which clearly describes the pulverization process.

Using adjustable speed crushing regeneration test device for the recovery experiment of thermosetting phenolic plastic waste, this paper analyses the principle of recovery process. Through particle size analytical technique, FTIR, XRD and SEM etc. various testing method is analyzed mechanochemical effects of crushing process. Research the speed, time, temperature process parameters of the influence of recycling process conditions. According to the experimental results, it established the mechanochemical model and analyzed the degradation and regeneration mechanism of thermosetting phenolic plastic waste.
