【摘要】：污水處理系統(tǒng)對于城市的污水處理是極為重要的，污水處理不但能夠解決城市污水環(huán)境和生活垃圾問題，更能減少現(xiàn)代城市中的環(huán)境污染問題。眾所周知，污水排水系統(tǒng)中，除了非常重要的污水處理系統(tǒng)設(shè)計外，更為重要的是要保證在污水處理過程中不發(fā)生泄漏，污水的泄漏，會污染城市地下水和土壤，破壞本已脆弱的現(xiàn)代城市生態(tài)系統(tǒng)，通過中外各國的調(diào)查發(fā)現(xiàn)，污水管道泄漏可以給現(xiàn)代城市造成不可估算的損失，針對以上問題，本文提出針對于污水輸水管道的的優(yōu)化分析，以天津市污水管道處理系統(tǒng)為實例，提出三種不同材料對污水管道進行優(yōu)化分析，同通過對比分析三種材料在三種工況下的具體分析，為現(xiàn)代城市污水處理系統(tǒng)提出建設(shè)性意見，本文主要研究了一下三個方面的內(nèi)容： 1）針對于現(xiàn)代城市污水處理系統(tǒng)所存在的問題以及對城市的危害做詳細的分析，盡可能的收集國內(nèi)污水處理系統(tǒng)存在的弊病，以及污水處理系統(tǒng)破壞對現(xiàn)代城市存在的某種潛在的威脅。并通過各國的數(shù)據(jù)和調(diào)研尋找出污水處理系統(tǒng)重要的環(huán)節(jié)，即污水管道輸水系統(tǒng)。 2）通過對污水管道的泄漏問題，本文提出了三種不但抗腐蝕性強，而且變形能力和強度同樣高的材料替代傳統(tǒng)的普通硅酸鹽材料，分別為玄武巖纖維混凝土與橡膠混凝土兩種特種混凝土材料，文中通過試驗研究證明橡膠集料混凝土和玄武巖纖維混凝土的強度、變形能力和耐腐蝕性遠強于普通混凝土，因此用玄武巖纖維混凝土和橡膠集料混凝土替代普通混凝土污水管道有極大的可行性。 3）通過有限元計算分析研究普通硅酸鹽混凝土、玄武巖纖維混凝土和橡膠集料混凝土在素混凝土的條件下的承載能力的不同，分析如果用玄武巖纖維混凝土和橡膠集料混凝土替代普通硅酸鹽混凝土存在的優(yōu)勢，文中采用近似等強度條件下，橡膠集料混凝土管道和玄武巖纖維混凝土管道的壁厚都可以優(yōu)化到42mm。 4）橡膠集料混凝土管道和玄武巖纖維混凝土管道的壁厚都可以優(yōu)化到42mm，此時兩種優(yōu)化后的管道，每米管道節(jié)省29.66kg混凝土，每公里節(jié)省2.966t混凝土，單從混凝土使用量的上，兩種不同混凝土管道是部分上下的，從橡膠和玄武巖纖維的成本分析，以及采用橡膠集料制作混凝土之后對環(huán)境的貢獻上來講，，橡膠集料混凝土管道更優(yōu)秀，對未來城市污水處理系統(tǒng)的建設(shè)提出了建設(shè)性意見。
[Abstract]:Sewage treatment system is very important for urban sewage treatment. Sewage treatment can not only solve the problems of sewage environment and domestic waste, but also reduce the environmental pollution in modern cities. As we all know, in the sewage drainage system, besides the very important design of the sewage treatment system, it is more important to ensure that there is no leakage in the sewage treatment process. The leakage of sewage will pollute the groundwater and soil in the city. Damage to the already fragile modern urban ecosystem, through the investigation of various countries at home and abroad, found that sewer leakage can cause incalculable losses to modern cities. In view of the above problems, In this paper, the optimization analysis of sewage pipeline is put forward. Taking Tianjin sewage pipe treatment system as an example, three kinds of different materials are put forward to optimize analysis of sewage pipeline. By comparing and analyzing the concrete analysis of three kinds of materials under three working conditions, this paper puts forward constructive suggestions for the modern urban sewage treatment system. This paper mainly studies the following three aspects: 1) aiming at the problems existing in the modern urban sewage treatment system and the harm to the city, and collecting the disadvantages of the domestic sewage treatment system as far as possible, And a potential threat to modern cities caused by the destruction of sewage treatment systems. And through the national data and research to find out the sewage treatment system important link, namely sewage pipeline water delivery system. 2) through the leakage of sewage pipes, this paper proposes three kinds of materials which not only have strong corrosion resistance, but also have the same deformability and strength to replace the conventional silicate materials. In this paper, the strength, deformation and corrosion resistance of rubber aggregate concrete and basalt fiber concrete are proved to be much stronger than that of ordinary concrete. So it is feasible to replace ordinary concrete sewer pipe with basalt fiber concrete and rubber aggregate concrete. 3) the difference of bearing capacity of ordinary silicate concrete, basalt fiber concrete and rubber aggregate concrete under plain concrete is studied by finite element analysis. If basalt fiber concrete and rubber aggregate concrete are used instead of ordinary silicate concrete, the advantages of using the similar strength condition are analyzed. The wall thickness of rubber aggregate concrete pipe and basalt fiber concrete pipe can be optimized to 42 mm. 4) the wall thickness of rubber aggregate concrete pipe and basalt fiber concrete pipe can be optimized to 42 mm. At this time, the two optimized pipes save 29.66kg concrete per meter pipe and 2.966t concrete per kilometer, only from the concrete usage. Two different kinds of concrete pipes are partially up and down, and rubber aggregate concrete pipes are better in terms of the cost analysis of rubber and basalt fibers, and the contribution to the environment of using rubber aggregates to make concrete. Constructive suggestions are put forward for the construction of urban sewage treatment system in the future.
