Description
Technical field
The present invention relates to a kind of technique, more particularly, to the handling process that fluid bed is used in a kind of sewage disposal.
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.
During present sewage disposal, its process is cumbersome, and efficiency is low, yields poorly.
The content of the invention
During it is an object of the invention to overcome above-mentioned existing sewage disposal, its process is cumbersome, and efficiency is low, and what is yielded poorly asks
Topic, devise the handling process that fluid bed is used in a kind of sewage disposal, the simple process, efficiency high.
The purpose of the present invention is achieved through the following technical solutions：The handling process of fluid bed is used in sewage disposal, including
Following steps：
（1）Fenton 1, No. 2 valve of water inlet is opened, intermediate pool No. 3 valves of draining is closed, opens intermediate pool elevator pump, Fenton
Reactor starts to intake；Observe inlet channel electromagnetic flowmeter, adjust the size of flow of inlet water by control valve, regulation to
Need flow；
（2）After the water inlet of Fenton's reaction tank, air-supplying valve is opened, it is inside reactor and rear reaction zone pond to open small roots blower
Interior carry out aeration agitation, tolerance size is adjusted by control valve；
（3）Each dosing valve of Fenton is opened, dosing mixer between dosing is opened, opens each dosing pump entrance end valve, open
Dynamic dosing pump starts dosing；The flow that observation dosing glass rotameter is shown, dosing is adjusted by adjusting return valve
Size is measured, is adjusted to the chemical feeding quantity needed for corresponding inflow；
（4）Reaction zone predominantly degassing pond, neutralization pond and sedimentation basin after Fenton, Fenton's reaction tank discharge water to degassing pond and taken off
Gas；Pay attention to monitoring the PH of pool inner water, pH value obtains height and directly affects reflection effect, finds the abnormal adjustment chemical feeding quantities in time of existing PH；
（5）Water outlet flows into neutralization pond by degassing pond, has sodium hydroxide chemical feeding points in neutralization pond, chemicals addition control PH is 6 --- 9 it
Between, notice that monitoring pH value notes abnormalities and adjust chemical feeding quantity in time；
（6）Water outlet flows into flocculation basin after neutralizing, and after water level in flocculation basin up to flocculation adjustable speed mixer after 2/3, is opened, slowly turns round
Dynamic adjusting switch, regulation mixer rotating speed is 500 --- between 800r/min, pay attention to the flocculation effect of flco in monitoring observation water
Fruit, the undesirable PAM of adjustment dosing in time of flocculating effect amount or mixer rotating speed etc.；
（7）Water outlet flows into Fenton's reaction sedimentation basin after the completion of flocculation, is first turned on east and west sides sedimentation basin inlet valve, regulating valve
Door makes sedimentation basin inflow essentially identical water inlet in both sides uniform；Two sedimentation basins can be run simultaneously with parallel running, also can interval
Operation；
（8）The regular spoil disposal of sedimentation basin, sludge-drainage time be every 6 hours be cycle spoil disposal 30min.
In summary, the beneficial effects of the invention are as follows：The simple process, efficiency high.
