In recent years, with the rapid development of the rural economy, while the living standards of rural residents have been greatly improved, the environmental conditions in the rural areas are not optimistic, and water pollution is one of the most important ones. Therefore, in order to improve the rural ecological environment and promote the task of water pollution control, Shandong Province has issued “the Governance Action Plan of black and odor water in rural areas of Shandong Province”. This article mainly uses “ the Action Plan” as a guide to analyze the current situation of rural black water bodies in Shandong Province and the current problems and related countermeasures, and follow the “comprehensiveness, applicability, economy, long-term effectiveness and safety. According to the black and odorous water problems caused by natural, technological and human factors, we will adopt comprehensive methods such as water purification, dredging, source control and pollution interception[1] to promote the treatment of black and odorous water bodies in rural areas, solve outstanding water environment problems in rural areas, and speed up construction of beautiful and livable countryside.

The work aims at discussing the essence of technology deconstruction and reorganization, and establishing the core value of technical decision-making in product micro-system design, In view of the current reality of neglecting product technology innovation. It clarifies the content of product technology and explores the ways and methods of product technology deconstruction and restructuring in the industrial design process. Industrial design is integration and inclusion, parallel design and collaborative design is the overall trend of its development, product technology design and modeling, man-machine and other design will eventually become unified. The innovation of working principle is the process of replacing the basic elements and modules or optimizing the state of material, information and energy transfer; product structure optimization is the process of mathematically finding the minimum design variables that meet the design requirements; the innovation of modeling material solutions is to solve the decision-making problem of the target multi-scheme; the processing technology improvement is to solve the process route optimization problem under multi-constraint conditions.
