2021 屆畢業(yè)生 畢業(yè)論文 題 目 : 高校生活垃圾資源化處理工藝設計 院 系 名稱: 化學化工學院 專業(yè)班級: 環(huán)境工程 1001 學生姓名: 鄭 天 家 學 號: 202148270103 指導教師: 許 春 紅 教師職稱: 講 師 2021 年 05 月 20 日 I 摘 要 隨著經(jīng)濟的發(fā)展,人們的生活水平 的提高 ,消費水平也在不斷地提高,生活垃圾的產(chǎn)生量也在不斷地提高。在高校里也不例外,高校作為當今社會一個特殊而且重要的組成部分,其通過教職工,學生等的日?;顒右矔a(chǎn)生大量的垃圾,這些垃圾的產(chǎn)生源主要來自辦公樓,宿舍區(qū),餐廳,教學樓等地方,而垃圾的組成成分由于產(chǎn)生源的不同也不盡相同,宿舍區(qū)、辦公樓和教學樓的垃圾種類主要有廢棄紙張,廢棄塑料,果皮,橡膠,玻璃等。而餐廳的垃圾種類主要有廢棄餐紙,食品包裝袋,菜葉,剩飯剩菜等。 而高校生活垃圾資源化處理,不僅能使我們的學校變得更干 整潔、干凈,而且能變廢為寶。 本設計主要是通過對高校內產(chǎn)生的生活垃圾中的有機固體 垃圾進行好氧 堆肥處理從而實現(xiàn)資源化。而堆肥是指在人為控制堆肥條件的基礎上 ,利用自然界中廣泛存在的微生物, 利用微生物對有機物中有機質的分解,促使堆 肥物料熟化, 向穩(wěn)定的腐殖質轉化的微生物學過程,利用微生物對有機垃圾分解腐熟而形成廢料的過程。通過對我校 —— 河南工業(yè)大學校內每日產(chǎn)生的生活垃圾進行分類篩選出有機固 體廢物,根據(jù)其產(chǎn)生量設計堆肥處理工藝的過程。通過對固體廢物的好氧 高溫 堆肥處理 ,可以實現(xiàn)垃圾資源化,減少有機垃圾對校園環(huán)境的影響,使我們的校園環(huán)境更加整潔。 關鍵詞 : 高校生活垃圾 資源化 好氧 堆肥 工藝設計 II Title Universities garbage treatment process design resources Abstract With economic development, people39。s living standards and consumption levels are constantly improved, the amount of garbage generated are constantly improving. There is no exception in college, university today39。s society as a special and important part of it will generate a lot of garbage by faculty, students and other daily activities, these sources of waste generated mainly from buildings, living quarters, dining , school buildings and other places, and the position of waste generated due to the different sources are not the same as living quarters, office and classroom building kinds of garbage mainly waste paper, waste plastic, peel, rubber, glass and so on. The main types of restaurant garbage food waste paper, food packaging bags, leaves, and other leftovers. The university garbage treatment resources, not only make our schools bee more charming neat, clean, and can change waste into treasure. This design is mainly through the garbage generated in the universities of anic solid waste posting be raised in order to achieve a good resource. The post is defined under manual control, the use of a wide range of microanisms present in nature, in a controlled manner to promote microbiological processes solid waste in biodegradable anic matter transformation to a stable humus, the use of microanisms to depose anic waste formed waste process. Through my school Henan University of garbage produced daily in schools classify selected anic solid waste posting process design according to their generation process. By good support posting of solid waste, waste resources can reduce the impact of anic waste on the campus environment.
