污水（英文：sewage,wastewater）受一定污染的来自生活和生产的排出水
生活污水、畜禽饲养场污水以及制革、洗毛、屠宰业和医院等排出的废水，常含有各种病原体，如病毒、
病菌、寄生虫。水体受到病原体的污染会传播疾病，如血吸虫病、霍乱、伤寒、痢疾、病毒性肝炎等。
历史行的瘟疫，有的就是水媒型传染病。如1848年和1854年英国两次霍乱流行，死亡万余人；
1892年德国汉堡霍乱流行，死亡750余人，均是水污染引起的。
市政污水处理工程(缺氧+传统活性污泥法)
某污水处理厂是芜湖室修建的一座大型污水处理厂。该厂的建设引进关键技术、监控装置和设备，提高污水处理效率，充分利用生物能，节约能耗，节省用地，降低工程造价和运行成本。
该污水处理厂的工艺设计，在进行各种工艺方案比较的基础上，仍选用鼓风曝气的设计方案。其理由是大型污水处理厂采用鼓风曝气工艺管理简便、运行可靠。该污水处理厂肖化吸收了国外的技术，对每个单项构筑物及污水、污泥处理的细部方案都作了改进，如进水泵房及污水量计量的自动控制、洗砂排砂、排泥浓度控制、溶解氧白控、脱氨反硝化工艺、二沉池出水槽新工艺、消化池投泥方式、大型消化池的沼气搅拌、沼气发电升压联网、沼气锅炉及排泥阀、可调堰、细格栅等技术都在该厂得到了应用。
本厂污水处理系统分4个系列，4个圆形初沉池排成一行，4个曝气池组成田字形，8座二沉池设在厂区南侧，临近北塘排水河，使处理出水可就近排人河道。污泥处理区设在厂的西北角，5个消化池组成梅花形，污泥处理的控制室设在5个捎化池的中央。北侧设有两个沼气储罐、污泥脱水机房和沼气发电机房等。
设备：
进水格栅是污水处理厂的道预处理设施。该厂设6台垂直格栅，由计算机程序控制。高水位时格栅清污机将连续工作，运送格栅拦截的浮渣的皮带运输机与格栅清污机联锁运行，在所有格栅停止工作后，皮带运输机仍将继续运行一段时间。
6台垂直格栅每台宽2m，栅条净距25 mm。
进水泵房
设6台HLWB-10型立式涡壳混流泵，5用1备。
泵房设有6个控制水位，控制5台泵的运行。为避免个别水泵负荷偏重而反复起动，水泵将依次循环投人运行。当某台泵因故障停止工作时，另一台泵将自动投入运行。
8台曲面格栅设在沉砂池的端部。每台格栅宽度1.2m，栅条曲率半径2.0 m，栅条净距10m。
每台格栅的清污动作根据水位模拟信号由计算机控制。当水位差处于正常值时，清污工作将按设定时间动作；当前后水位差超过设定值时，清污工作将连续进行。如果清污工作连续操作时间过长，计算机将发出报警信号。
曲面格栅刮出的浮渣落在皮带运输机上，皮带运输机的运行与格栅清污机联锁，清污工作停止后，运输机仍将运行一段时间。
曝气沉砂池设有6条廊道，每条长30m、宽4m、深4.3m，水力停留时间约6min。
池内设有振动空气(VIBRAIR)曝气器648个，供气量为5184立方米/小时。全池设两座吸砂工作桥，每个工作桥上有3个空气提砂装置，负责3条廊道的吸砂。污秽的砂水被提升到洗砂槽，经搅拌后，有机物随洗砂水流回进水泵房，砂水被送至分砂机进行进一步脱水。分砂机设在进水泵房的上部建筑顶层，以便脱水的砂粒流入砂斗运走。
吸砂工作桥用行程开关控制，其上设有刮渣设施，以清除池内浮渣。空气提砂装置要求注续工作，由计算机控制。当空气压缩机发生故障时，备用机可自动投入。空气压缩机、分砂机和泵的运行状态由计算机监控，如出现故障将自动报警。
初沉池曾设计了矩形和圆形两种方案，从运行管理、占地和混凝土用量等方面进行比较，认为圆形辐流式沉淀池设备运转可靠、管理简便，故采用了4座配有周边驱动全桥式刮混机的辐流式沉淀池，直径达60m，水深4.5 m，沉淀时间2.26h。
初沉池运行的关键是排泥，4座池轮流排泥的程序由计算机控制。每个排泥阀靠频率/时间自动操作。其功率/时间将根据计算机监测到的污泥浓度和流量束进行调整。排泥阀分两部分，启用的是电动阀门，排泥口用的是可手动调节的升降阀，该阀属非标设备。
为防止排泥系统出现堵塞故障，在两座初沉池间设一座污泥泵房。安装GF单螺杆泵4台，两座泵房共装8台污泥泵。污泥泵按频率邝j问自动操作，并由计算机进行调整，两座污泥泵房交替运行，在泵房的出口处设有污泥浓度模拟测量装置，污泥进人浓缩池前进行
流量检测。这些信号进入计算机后，将用于计算污泥的排放量，以调整排泥技术上频率和排混的持续时间。

Sewage (sewage, wastewater) from life and production of contaminated water
Wastewater from domestic sewage, livestock and poultry farms, and effluent from tannery, hair washing, slaughtering and hospitals often contain various pathogens, such as viruses,
Germs, parasites. The water body is contaminated by the pathogen, such as schistosomiasis, cholera, typhoid, dysentery, viral hepatitis and so on.
The history of epidemic plague, some waterborne infectious diseases. For example, in 1848 and 1854, two cholera was popular in Britain and more than 10000 people died.
In 1892, Hamburg cholera was popular in Germany, and more than 750 people died, all of which were caused by water pollution.
Municipal sewage treatment project (anoxia + traditional activated sludge process)
A sewage treatment plant is a large sewage treatment plant built in the Wuhu room. The key technologies, monitoring devices and equipment are introduced to improve the efficiency of sewage treatment, make full use of bio energy, save energy, save land and reduce project cost and operation cost.
On the basis of the comparison of various technological schemes, the design scheme of air blast aeration is still used in the process design of the sewage treatment plant. The reason is that the large sewage treatment plant uses blast aeration technology to be easy to manage and operate reliably. The sewage treatment plant Xiao of absorbing foreign advanced technology, sewage and sludge treatment structures and the detail scheme of each individual were improved, such as the pump room and sewage metering automatic control, sand washing, sand mud concentration control, dissolved oxygen control, white ammonia denitrification process two, sedimentation tank tank process, digestion tank, large investment mud digester biogas stirring, biogas power generation, biogas boiler and boost network mud valve, adjustable weir, fine grid and other advanced technologies are applied in the factory.
The sewage treatment system of our factory is divided into 4 series, 4 circular primary settling tanks are arranged in one row, 4 aeration tanks form a field shape, and 8 sets of two sedimentation tanks are located on the south side of the factory area, near the drainage river of Beitang, so that the treated water can be drained near the river. The sludge treatment area is located in the northwest corner of the factory. The 5 digests are composed of plum blossom shape, and the control room of sludge treatment is located in the center of the 5 carrier pools. There are two biogas storage tanks, sludge dewatering machine room and biogas generator room on the north side.
Equipment:
The inlet grille is the first pretreatment facility for the sewage treatment plant. The plant has 6 vertical grille, which is controlled by computer program. When the water level is high, the grille cleaning machine will interlock and run continuously with the grille intercepting scum belt conveyor and the grille cleaning machine. After all grille stops, the belt conveyor will continue to run for a period of time.
6 vertical grille is 2m with a width of 25 mm.
Inflow pump room
There are 6 HLWB-10 vertical vortex shell mixed flow pumps, 5 for 1.
The pump room has 6 control water levels to control the operation of 5 pumps. In order to avoid the heavy load of individual pumps, the pump will circulate and run in turn. When a pump stops working because of a failure, the other pump will be put into operation automatically.
8 curved grille are located at the end of the sand sink. The width of each grid is 1.2m, the radius of curvature of the gate is 2 m, and the net distance of the gate bar is 10m.
The cleaning action of each grid is controlled by the computer according to the analog signal of the water level. When the water level difference is in the normal value, the cleaning work will act according to the setting time; when the current water level difference exceeds the set value, the cleaning work will be carried out continuously. If the cleaning work is too long for a long time, the computer will send out the alarm signal.
The scum scraped from the surface grille falls on the belt conveyor. The operation of the belt conveyor is interlocked with the grille cleaning machine. After the cleaning operation is stopped, the transporter will still run for a period of time.
The aeration and sand sedimentation tank has 6 corridors with a length of 30m, wide 4m and deep 4.3m, and the hydraulic retention time is about 6min.
The tank has a vibratory air (VIBRAIR) aerator with 648 gas supply of 5184 cubic meters per hour. There are two sand suction working bridges in the whole pool. There are 3 air lifting devices on each working bridge, which is responsible for the sand suction of the 3 corridors. The polluted sand is raised to the sand washing tank. After mixing, the organic matter is returned to the pump room with the flow of sand washing. The sand water is sent to the sanding machine for further dehydration. The sand separator is located on the top floor of the upper building of the inlet pump room, so that the dehydrated sand is flowing into the sand bucket.
The sand suction working bridge is controlled by a stroke switch, and a slag scraping facility is provided to remove the slag in the pool. The air lifting device requires continuous work and is controlled by a computer. When the air compressor fails, the standby machine can be automatically put into operation. The operating state of air compressor, sanding machine and pump is monitored by computer. If failure occurs, it will alarm automatically.
The primary settling tank was designed with rectangular and circular two schemes were compared from the operation and management, and the amount of concrete covers and so on, that circular radial flow sedimentation tank equipment, reliable operation, convenient management, so the use of the 4 seat equipped with peripheral drive full bridge scraping mixer the radial flow sedimentation tank, diameter of 60m the depth of 4.5 m, precipitation time 2.26h.
The key to the operation of the initial sedimentation tank is the sludge discharge, and the program for the 4 pools to drain the mud is controlled by the computer. Each sludge discharge valve is operated automatically by frequency / time. The power / time will be adjusted according to the sludge concentration and flow beam monitored by the computer. The sludge discharge valve is divided into two parts, which is operated by electric valve. The mud outlet is a manual adjustable lift valve. This valve belongs to non standard equipment.
In order to prevent the plugging of the sludge system, a sludge pump room is set up between the two primary sedimentation tanks. Installation of GF single screw pump 4 units, two pump rooms with a total of 8 Sludge pumps. The sludge pump is automatically operated at the frequency Kuang J, and is adjusted by the computer. Two sludge pump houses
