小型医院地埋式一体化污水处理设备
1、污泥处理
污泥池中的污泥通过好氧消化后,定期处理。
2、防渗措施
本污水处理站中采用钢筋混凝土制作的池,为了避免地下水渗入或污水渗出,钢筋混凝土采用防渗设计。
3、除臭措施
由于缺氧池、好氧池、污泥池都需充氧曝气,因此曝气后溢出水面的气体有一定的臭味,如果这些臭气不加以处理势必影响周围环境,造成二次污染。我们将调节池、缺氧池、好氧池、污泥池顶盖上引出通风口,整套设备运行**,管理方便,其设备投资相应较小。
4、降噪措施
本污水处理站*主要的噪声来源是鼓风机,为此我们采用一系列措施降低噪声。本污水处理站采用罗茨风机布置在风机房内,在风机基础下设置隔振垫,并在风机进风口上安装消声器,在出风口上安装可曲挠橡胶接头,以减少振动产生的噪声。
充氧采用水下曝气机,噪音小,充氧效率高。曝气机安装在水下,可以随时提升上来维修,技术特点如下:
⑴氧溶解率高,微小气泡所占比列大,充氧效率高且充氧面积宽;
⑵池中无死区,夹带气泡的水平水流*冲刷池底的每个角落;
⑶结构简单、紧凑、机组寿命长,能承受大负荷的轴承、采用油浴的转轴机械密封和吸入叶轮腔内的空气防止工作时与密封件接触,这些都保证曝气机在24小时连续工作,**运行;
⑷与常规的鼓风曝气方式相比,无需建设鼓风房,无需气泵和输气管道,安装方便,维修工作量小,占地面积少;
⑸使用灵活,当池内设有多台沉水式曝气机时,可根据需要增减曝气机的运行数量,容易实现曝气量的调节和节能效果;
⑹曝气机工作时,兼具有搅拌功能,避免污泥在池低沉淀;当进气口关闭时,也可作为搅拌机使用。
医院污水来源及成分复杂,含Y病原性微生物、有毒、有害的物理化学污染物和放射性污染等,具有空间污染、急性传染和潜伏性传染等特征,不经**处理会成为一条疫病扩散的重要途径和严重污染环境。医院污水受到粪便、传染性细菌和病毒等病原性微生物污染,具有传染性,可以诱发疾病或造成伤害。医院污水中含有酸、碱、悬浮固体、BOD、COD和动植物油等有毒、有害物质。牙科**、洗印和化验等过程产生污水含有重金属、消毒剂、有机溶剂等,部分具有致癌、致畸或致突变性,危害人体健康并对环境有长远影响。同位素**和诊断产生放射性污水。放射性同位素在衰变过程中产生a-、β-和γ-放射性,在人体内积累而危害人体健康。
The underwater aerator is used for aeration with low noise and high aeration efficiency. The aerator is installed underwater and can be lifted up and maintained at any time. The technical characteristics are as follows:
(1) High oxygen dissolution rate, large proportion of micro bubbles, high oxygen filling efficiency and wide oxygen filling area;
(2) There is no dead zone in the pool, and the horizontal flow with bubbles completely scours every corner of the bottom of the pool.
_The structure is simple, compact, the life of the unit is long, bearings can withstand heavy loads, mechanical seals of rotating axles using oil bath and air inhalation in impeller chamber are used to prevent contact with the seals when working. All these ensure that the aerator works continuously for 24 hours and has long-term trouble-free operation.
(4) Compared with conventional blast aeration, there is no need to build a blast room, no need for air pumps and gas pipelines. It is easy to install, less maintenance work and less floor area.
(5) Flexible use. When there are several submerged aerators in the tank, the number of aerators can be increased or decreased according to the need, which can easily realize the adjustment of aeration volume and energy saving effect.
(5) When the aerator works, it has the function of stirring to avoid low sludge deposition in the tank; when the intake is closed, it can also be used as a mixer.
