Influent and effluent COD, turbidity, color and total bacterial counts were analyzed for more than one year. All results showed that, performances of the slow sand filter were nearly the same with its filtration rate 0.3 m/h or 0.1 m/h., but decreased dramatically when its filtration rate was increased to 0.5 m/h from 0.3 m/h. Temperature decrease had a significant negative effect on COD removal but not on turbidity or bacterial removal. The schmutzdecke layer contributed more than half quantities of pollutants removal. Average effluent of COD, turbidity, color and total bacterial counts were 34.9 mg/L, 0.6 NTU, 23.3° and 6200 CFU/ml respectively and corresponding removal rates were 43.9%, 89.5%, 55.6% and 73.5% under filtration rate 0.1 m/h in Summer.","PeriodicalId":6349,"journal":{"name":"2010 International Conference on Mechanic Automation and Control Engineering","volume":"32 1","pages":"4942-4944"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77837561","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}

And also the main working modes, such as switch between working modes, rebounding test, reposition of the piston assembly, compression and cushion, were illustrated. This paper paid great emphases on the introduction of the structures of the compression chamber and compression piston. It was indicated that the compression time to push the piston move was prolonged with the increasing of the distance between the main port and the trigger port. The increase of the length and angle of the piston wedge would reduce the compression performance, while the cushion performance would be enhanced. With the opening length increasing, the compression time to push the piston move was shorter and the compression performance is improved.","PeriodicalId":6349,"journal":{"name":"2010 International Conference on Mechanic Automation and Control Engineering","volume":"23 1","pages":"6215-6219"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73151396","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}

This system offers a tremendous opportunity for a new kind of communication. The implementation of such a system has been made possible only by the advent of the Internet and distributed programming, increasing the flexibility of the client-server-based approach. The architecture, detailed functional models, and implementation of the system have been presented. As part of the architecture, the concept of an application independent server composed of autonomous modules is proposed. Ideally the user can access the system from any part of the world through the Internet.","PeriodicalId":6349,"journal":{"name":"2010 International Conference on Mechanic Automation and Control Engineering","volume":"1 1","pages":"3057-3060"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79917004","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}

The further reason is that the local governments in coastal area can't adhere to the outlook in scientific development in the course of economic development seriously. They only pay attention to the growth of GDP and can't deal with the relation beween the economic development and environmental protection well. This leads to the coastal residents' indifferent consciousness for protecting marine environment. In my opinion, the following work should be done for environmental protection of ocean. The outlook in scientific development must be carried out by local governments and the departments for marne development, and ocean ought to be developed in a scientific way conscientiously. The enterprises with serious pollution must be restricted for continuous expansion. Meanwhile, law enforcement should also be strengthened and some enterprises which pollute ocean must be punished sternly. The coastal residents must encouraged to participate in the marine management for marine environment protection.","PeriodicalId":6349,"journal":{"name":"2010 International Conference on Mechanic Automation and Control Engineering","volume":"126 1","pages":"1874-1877"},"PeriodicalIF":0.0,"publicationDate":"2010-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76829521","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}
