Description
Technical field
The present invention relates to a kind of method, more particularly, to a kind of sewage water treatment method.
Background technology
Sewage, it is often referred to discharge water necessarily polluted, from life and production.Sewage mainly has sanitary sewage, work
Industry waste water and early-stage rainwater.The ill pathogen contaminant of major pollutants, oxygen consumption pollutant, plant nutrient and the poisonous dirt of sewage
Contaminate thing etc..According to the viewpoint of sewage source, sewage can be defined as from the discharge of house, office, business or industrial area and ground
The liquid or water that carry waste of the mixing such as lower water, surface water, snowstorm.Sewage is correspondingly reduced dirty by many classifications
Influence of the water to environment also has many technologies and technique.According to sewage source, sewage can be divided into this four class.
The first kind：Sewage of the industrial wastewater from manufacturing, mining and industrial production activities, including from industry or business
Industry storage, processing runoff live leachate, and it is other be not sanitary sewage waste water.
Second class：Sanitary sewage is from house, office building, office or similar sewage；Hygienic sewage；Sewer is dirty
The industrial wastewater mixed in water, including sewerage system in sanitary sewage.
3rd class：Business sewage exceedes nontoxic, the harmless dirt of sanitary sewage from commercial facility and some compositions
Water.Such as sewage from catering business.Sewage of wash house, animal feeding sewage, sewage etc. caused by hairdressing place.
4th class：Overland flow water, the water from city and industrial area etc. under rainwater, snow-broth, highway
Deng overland flow does not infilter soil, enters underground water along street and land.
In water pollution caused by human production activity, water pollution most serious caused by industry.Such as industrial wastewater, it contains
Pollutant is more, complicated component, not only is not easy to purify in water, and handles also relatively difficult.
Industrial wastewater, it is the most important reason that industrial pollution causes water pollution.It accounts for the pollutant of industry discharge
It is most of.Pollutant contained by industrial wastewater varies because factory's species is different, even same class factory, production process is not
Together, the quality and quantity of its contained pollutant is also different.Industry is in addition to the waste water of discharge is directly injected into water body and causes pollution, solid
Waste and waste gas also can polluted-waters.
Agricultural pollution, which is firstly because farming or opened up wasteland, makes soil surface porosity, is dropped in soil and also unstable landform
Rain, a large amount of silts are flowed into water, increase the suspension in water.
An also major reason is that agricultural chemicals, the usage amount of chemical fertilizer are increasing, and the agricultural chemicals and chemical fertilizer used is only few
Amount attachment is absorbed, and remaining overwhelming majority remains in soil and floating in an atmosphere, by rainfall, by rushing for rainwash
Brush, which enters surface water and penetrates into surface water, forms pollution.
Urban pollution resource is because urban population is concentrated, caused by city domestic sewage, rubbish and waste gas cause water pollution.
Pollution of the urban pollution resource to water body is mainly sanitary sewage, and it is the mixing of caused various sewage in people's daily life
Liquid, including the sewage of kitchen, washing room, bathroom and lavatory discharge.
Present sewage treatment process is complicated, and treatment effeciency is poor so that environment is polluted after discharge.
The content of the invention
It is an object of the invention to overcome above-mentioned existing sewage treatment process complicated, and treatment effeciency is poor so that discharge
The problem of polluting environment afterwards, devises a kind of sewage water treatment method, simple the step of this method, can be clean by sewage disposal,
Environmental protection, solves existing sewage treatment process complexity, and treatment effeciency is poor so that the problem of environment is polluted after discharge.
The purpose of the present invention is achieved through the following technical solutions：A kind of sewage water treatment method, comprises the following steps：
（1）Two block response devices water inlet flowing water Valve is opened, opens Sand Filtration System and to catalytic ozonation reactor inlet pipeline
Valve, reactor start to intake；Observation water inlet electromagnetic flowmeter, regulating water inlet valve door, regulation and control flow of inlet water is in the range of needs；
（2）Reactor aeration supervisor and 10 branch pipe valves are opened, air blower starts, and sewage starts aeration agitation in reactor；
（3）Reactor sulfuric acid dosing tube valve is opened, starts sulfuric acid dosing pump, reactor starts dosing, control water quality pH value 3-
6, predominantly early stage debugs catalyst in pickling reactor and added；
（4）Open ozone and add pipeline valve, start oxygen and ozone generation system processed, appropriate tune is carried out by the dosage of ozone
The loading power of whole ozone generator, starts to add ozone；
（5）The water outlet of catalytic ozonation process system can enter biochemical hydrolysis acidification pool and hydrolysis acid by switching adjustment valve
Change water quality mixing pit, when water COD concentration is higher by 400 --- during 500mg/L or more than 500mg/L, close two side mixing pits and enter
Penstock, opens hydrolysis acidification distribution reservoir inlet valve, and water enters biochemical hydrolysis acidification pool；If opposite water COD concentration is smaller,
Then switch valve enters mixing pit；Avoid when COD pollutant concentrations are low, ozone and organic pollution reaction are incomplete, water outlet
The excessive biochemical hydrolysis acidification pool that enters of middle ozone residual quantity kills broken, bad microorganism fungus kind, is caused greatly to hydrolysis acidification pool
Harm；
（6）Ozone process system flowback pump is provided with hydrolysis acidification mixing pit, is needed to adjust backflow pump valve tune according to technique
Return flow is saved, capacity of returns is controlled 50% --- between 100%.
In summary, the beneficial effects of the invention are as follows：The step of this method, is simple, can be clean by sewage disposal, protection
Environment, solves existing sewage treatment process complexity, and treatment effeciency is poor so that the problem of environment is polluted after discharge.
