In this paper, we evaluated the achievements of rural domestic sewage treatment from the aspects of regulations and standards, treatment scale and technology, and environmental protection education, and analyzed the problems associated with treatment capacity, technology, standards, and operation and maintenance. Rural domestic sewage treatment should adapt to local conditions, focus on resource utilization, and be economical, convenient, and scientifically planned. Key tasks were proposed from the perspectives of treatment mode, technical process, resource utilization, and operating mechanism. The development path we proposed emphasizes systematic treatment and integration of all parties. Moreover, several countermeasures are suggested. Discharge standards should be formulated scientifically for rural domestic sewage as nitrogen and phosphorus in rural sewage needs to be reused for irrigation. Ecological and simple treatment of the rural domestic sewage should be promoted based on the economical and feasible principles. The market mechanism needs to be improved to promote the specialized trusteeship of rural sewage treatment.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67372340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hence the cyberspace has become an open-air dump of content big data. The emerging content big data characterized by chaos, disorder, and difficulty in governance brings severe challenges to the sustainable development of the Internet. Inspired by the idea of commensalism, a dual-meta network architecture driven by content and address is proposed in this paper which combines the primary structure of address-driven Internet with a secondary structure of content-driven broadcast-storage network. Specifically, the address-driven features and challenges of Internet architecture are analyzed, and some representative content-centric networking schemes and their limitations are discussed. Then, the design principles for dual-meta network architecture and the content-driven metadata of uniform content label are introduced. Eventually, a reference model of the dual-meta network architecture is given, and its differences compared with a single address-driven Internet architecture are analyzed. As an innovative network architecture characterized by security, trustworthiness, pervasiveness, guarantee of sovereignty, and easy governance, the dual-meta network architecture driven by content and address provides a feasible new way to solve the development dilemma faced by the single address-driven Internet architecture.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67370603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

China has always attached great importance to guaranteeing drinking water safety. Since China’s reform and opening up in 1978, water environmental pollution has brought great challenges to drinking water safety in the Yangtze River Delta region owing to active economic development and high population density in the region. After over ten years of development, the overall level for guaranteeing drinking water safety in the Yangtze River Delta region has significantly improved, effectively promoting the coordinated and sustainable development of the region. However, as people’s requirements for water quality and health gradually increase, work for guaranteeing drinking water safety in the megalopolis agglomeration of Yangtze River Delta faces various challenges. In this article, we analyze the water quality characteristics of typical water sources in the Yangtze River Delta region, and summarize the achievements in urban drinking water safety assurance of the region. Suggestions are proposed from two dimensions (i.e., management and technology) and three aspects (i.e., water source, water plant, and secondary water supply), including improving the ecological compensation mechanism, collaboratively revising water quality standards, developing green and efficient purification technologies, and innovating the water supply management model. These strategies can provide a reference for assuring drinking water safety and promoting regional integration in the Yangtze River Delta and other key regions.","PeriodicalId":65586,"journal":{"name":"中国工程科学","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67371781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
