Abstract

一种污水处理装置，内部由一带落水口的横板将 装置分为上下两部分，上部为生物滤池，下部为接触 氧化池，在该装置内完成污水的二级生化处理，该装 置占地少、能耗少、去除率高，耐冲击、易管理，不外排 过剩的污泥和废气，减轻了二次污染。

Description

石油炼厂、化工厂等污水处理大多采用活性污泥法，该法剩余污泥多，易发生污泥膨胀，操作管理困难，并且占地面积大，运行费用高，文献调研中发现近几十年来，国内外许多企业采用生物滤池处理代替传统的活性污泥法，由于生物滤池处理工艺去除率低，只能在低有机负荷条件下运行，还有的企业采用生物滤池与接触氧化池及活性污泥法串联的工艺，这种串联的方式占地面积大，运行费用高，不易管理。
本发明的目的在于研究开发一种占地面积小、处理效果好、能耗低、管理方便，运行费用低，能处理各种污水，包括海、淡混合污水的污水处理装置。
本发明污水处理装置上部设有污水进水线、冲洗水线及空气排出线，装置的下部按装有进气线和出水线，装置内一带有落水口的水平汇水板将装置分为上下两部分，汇水板上部分为生物滤池、下部为接触氧化池，在汇水板的上部有一与汇水板平行的筛板，筛板以上的滤池中装有陶瓷软性填料，汇水板下面的接触氧化池内设有折流挡墙，在接触氧化池内也装有陶瓷软性填料。
待处理污水从污水进水线进入生物滤池处理，然后经筛板渗滤，由汇水板汇集到装置的一端，经落水口排到接触氧化池，经处理后的水从接触氧化池直接排出，空气经鼓风机从接触氧化池底部进入，经生物滤池的落水口进入生物滤池，然后从装置顶排出，接触氧化池中设有折流挡墙，可延长水流过的长度，使污水中的污染物含量在装置内形成明显的梯度，经过充分处理后，从出水线排出。
本发明污水处理装置的壁部，生物滤池内的筛板，汇水板及接触氧化池内的折流挡墙均由钢筋混凝土制成。
本发明是在同一装置内完成污水的二级生化处理装置，上部的生物滤池为予处理设施，下部的接触氧化池为进一步处理设施。接触氧化池过剩的空气经上部生物滤池后排出，造成生物滤池的强制供风，这样不仅提高了氧的利用率，也有利于提高生物滤池的处理效果，同时废气经过生物滤池时，其中的有害物质可以被滤池中的污水吸收，经生物氧化后分解，减轻了二次污染。
本发明污水处理装置占地少，效率高，耐冲击、易管理，费用低，不外排过剩的活性污泥，对污染物去除率高。该装置用于处理炼油厂含油污水，当原水水质硫化物含量≤200mg/l，挥发酚含量≤200mg/l，石油类含量≤60mg/l时，处理后水中硫化物＜1mg/l，挥发酚＜1mg/l，石油类＜5mg/l。
该装置不仅可以处理炼油厂，也可处理化工、染料等其它行业生产中产生的污水。
图1为本发明生物氧化污水处理塔的内部结构示意图。
下面结合附图来说明本发明的一个实施例。
图1中，1是生物氧化污水处理塔的塔壁、2是筛板、3是冲洗水线、4是污水进水线、5是生物滤池、6是汇水板、7是出水线、8是接触氧化池、9是折流挡墙、10是进气线、11是落水口、12是空气排出线。
待处理污水由进水线4进入生物滤池5，经一次生化处理的水通过筛板2的渗滤由汇水板6汇集到塔的一端，然后从落水口11排到接触氧化池8，由于接触氧化池中折流挡墙9的作用，污水中污染物含量形成明显梯度，在接触氧化池中污水经二次生化处理后从出水线7排出。
该生物滤池除有污水进水线外，另外设有冲洗水线3，在污水处理塔正常运行一定时间后，用大量新鲜水进行冲洗，加速生物滤池填料上生物膜的脱落、更新和排出，防止生物滤池堵塞。
压缩空气通过进气管线10进入接触氧化池8，又通过落水口11进入生物滤池，最后由塔顶空气排出线12排出。
塔壁及内部设施全部由钢筋混凝土制成，塔内填料均为陶瓷软性填料。
