汽车清洗污水回收系统的设计(CATIA三维图)(任务书,开题报告,论文说明书7800字,CATIA三维图)
摘要
摘要：本设计为洗车污水系统处理设计。洗车污水废水中油类是主要污染物质，因此要设计除油装置，本设计是通过处理污水中的油、泥砂等污染物，使水可以重新利用进行洗车。先通过格栅以及污水池对水中大颗粒进行过滤，然后经过隔油池处理油污，再进过混凝反应加斜板沉淀池，对水中小颗粒进行沉淀处理，最后再经过活性炭去除色度以及加入消毒液对水进行消毒，最终可以达到再次洗车的标准。本设计有着处理效果好，工艺简单，占地面积省，运行稳定，能耗少的优点。洗车污水水处理系统的效益巨大，每年都浪费很多的水资源，为了让污水处理技术有效的实现节约用水，保证出水水质可以重新洗车，将自动控制技术运用于污水处理中，提高污水处理的自动化水平已经成为污水处理中的关键问题。
本文以洗车污水处理的设计为基础，结合污水处理工艺，探讨如何自动进行污水处理，并充分考虑污水处理系统的运行。本文主要介绍了隔油池、混凝池、过滤池等污水处理过程。

Abstract
Abstract: This design is the treatment of car washing wastewater system. The water quality characteristics of oil washing wastewater is the main pollutant in car washing wastewater. According to the oil pollutant of car washing wastewater is divided into two major categories: the first is less oil, car washing wastewater with mud and sand, detergent more; the second is oil content, mud and sand, detergent like substances were higher for the car washing wastewater, this kind of wastewater treatment process is relatively complex. The design of car washing wastewater of oil, mud and sand, detergent substances were higher. First through the grille and sewage pool of water particle filter and after the pool that lie between oil processing oil, and then go to mixed agglutination and inclined plate sedimentation tank, sedimentation treatment of small particles of water, finally through the activated carbon removal of chroma and add the disinfectant for water disinfection, can attain the standard car wash again. This design has a good treatment effect, simple process, small occupied area, stable operation,low power consumption advantages. Car washing sewage water treatment system of great benefit, the annual waste a lot of water resources, in order to let the sewage treatment technology effectively realize water saving to ensure water quality may be re washing, automatic control technology used in wastewater treatment, improve the automation level of wastewater treatment has become a key problem in sewage treatment.
In this paper, based on the design of car washing wastewater treatment, considering the process of sewage treatment, investigate how to automatically for sewage treatment, and give full consideration to the operation of sewage treatment system. This paper mainly introduces the oil separation tank, flocculation tank, filter and other sewage treatment process.

洗车场数据的设定
本设计假设洗车店是10个车位的，用高压水枪洗车的话，每辆车洗车用水大概100L，洗一辆车要10分钟。每天洗200辆车，每天20吨污水。若流量q=6 m3/h、流速u=0.6 m/s。管径计算公式： d=18.8×[(q/u)^(0.5)]=40.3选择DN40的水管。DN40 外半径48.3壁厚3.5[3]。按平均每天20吨污水进行设计。污水处理2个小时可进行再次利用。洗车场每天工作8个小时，因此污水处理系统容积要在5吨以上。在洗车污水进入污水处理系统前，要有简单的过滤处理，除去沙粒以及树叶的大物体，起到保护污水处理系统不被堵塞以及损坏。
