Description
Technical field
The technique purged the present invention relates to a kind of technique, during more particularly, to a kind of sewage disposal to pipeline.
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：Industry
Sewage of the waste water from manufacturing, mining and industrial production activities, including lived from the runoff stored, processed with industry or business
Leachate site, and it is other be not sanitary sewage waste water.Second class：Sanitary sewage is from house, office building, office or similar
As sewage；Hygienic sewage；The industrial wastewater mixed in effluent sewerage, including sewerage system in sanitary sewage.3rd class：
Business sewage exceedes nontoxic, the harmless sewage of sanitary sewage from commercial facility and some compositions.Such as sewage from catering business.Wash
Clothing room sewage, animal feeding sewage, sewage etc. caused by hairdressing place.4th class：Overland flow is from rainwater, snow-broth, highway
Lower water, water from city and industrial area etc., 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
It is more, complicated component, not only it is not easy to purify in water, and handle also relatively difficult.Industrial wastewater, it is that industrial pollution causes water body
The most important reason of pollution.It accounts for the major part of the pollutant of industry discharge.Pollutant contained by industrial wastewater is because of factory's kind
Class is different and varies, even same class factory, production process is different, and the quality and quantity of its contained pollutant is also different.Work
For industry 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 is first
It is due to first that farming or the reclamation of wasteland make soil surface porosity, the rainfall in soil and also unstable landform, 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 used and change
The only a small amount of attachment of fertilizer is absorbed, and remaining overwhelming majority remains in soil and floating in an atmosphere, by rainfall, by earth's surface
Washing away into surface water and infiltration surface water for runoff forms pollution.Urban pollution resource is the urban life because urban population is concentrated
Caused by sewage, rubbish and waste gas cause water pollution.Pollution of the urban pollution resource to water body is mainly sanitary sewage, and it is people
The mixed liquor of caused various sewage in daily life, including the sewage of kitchen, washing room, bathroom and lavatory discharge.
Only just up to 500 cubic kilometers of the industrial and life contaminated water of the discharge of urban area 1 year in the world, and each drop sewage will pollute
The water body of several times or even decades of times.
During present sewage disposal, purged for pipeline inside not in place so that pipeline blocks, and causes sewage disposal to imitate
Rate is low.
The content of the invention
During it is an object of the invention to overcome above-mentioned existing sewage disposal, purged for pipeline inside not in place so that pipe
Road blocks, the problem of causing sewage treating efficiency low, the technique purged when devising a kind of sewage disposal to pipeline,
The technique make it that sewage treating efficiency is high, effectively can prevent sewage from blocking, sewage disposal reaches requirement.
The purpose of the present invention is achieved through the following technical solutions：A kind of technique purged during sewage disposal to pipeline,
The equipment and pipeline for not allowing purging should isolate with purging system；The instrument that pipeline should be connected before purging is protected by, important
Valve, regulating valve, safety valve, instrument, orifice plate etc. should take corresponding safeguard measure；Check whether pipe-hanger support firmly may be used
Lean on, should give reinforcing if necessary；Mark should be carried out by purging the parts removed and temporary stop plate, be kept properly, and blowing pipeline closes
Resetted after lattice, the source of the gas of blowing pipeline can utilize the compressed air of outer confession, and the design pressure of gas tank used in purging should be big
In purging pressure, purging answers discontinuity to carry out, and should be carried out with maximum stream flow during purging, and air velocity cannot be less than 20m/s, purging
During, in outlet calico or the target plate inspection of white paint should be scribbled, in 5min, without iron rust and other miscellaneous on target plate
Thing is qualified, purges qualified pipeline, pipeline is sealed in time, and fills in blowing pipeline record.
In summary, the beneficial effects of the invention are as follows：The technique make it that sewage treating efficiency is high, can effectively prevent sewage
Block, sewage disposal reaches requirement.
Embodiment
With reference to embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited only to
This.
Embodiment：
A kind of technique purged during sewage disposal to pipeline, do not allow purging equipment and pipeline should with purging system every
From；The instrument that pipeline should be connected before purging is protected by, and important valve, regulating valve, safety valve, instrument, orifice plate etc. should be adopted
Take corresponding safeguard measure；Check whether pipe-hanger support is solid and reliable, should give reinforcing if necessary；Purge the parts removed
And temporary stop plate should carry out mark, keep properly, resetted after blowing pipeline is qualified, the source of the gas of blowing pipeline can utilize the pressure of outer confession
Contracting air, the design pressure of gas tank used in purging should be greater than purging pressure, and purging answers discontinuity to carry out, should be with during purging
Maximum stream flow is carried out, and air velocity cannot be less than 20m/s, in purge, in outlet calico or should scribble white paint
Target plate inspection, in 5min, without iron rust and other debris be qualified on target plate, purge qualified pipeline, pipeline is entered in time
Row sealing, and fill in blowing pipeline record.
The technique make it that sewage treating efficiency is high, effectively can prevent sewage from blocking, sewage disposal reaches requirement.
It is described above, be only presently preferred embodiments of the present invention, any formal limitation not done to the present invention, it is every according to
Any simply modification, the equivalent variations substantially made according to the technology of the present invention, method to above example, each fall within the present invention
Protection domain within.
