Description
Technical field
The present invention relates to environmental technology field, more particularly to a kind of sewage treatment process.
Background technology
Sewage disposal is widely used in building, agricultural, traffic, the energy, petrochemical industry, environmental protection, urban landscape, medical treatment, food and drink
Etc. every field, the daily life of common people is also come into more and more.
Classify by sewage source, sewage disposal is generally divided into production wastewater treatment and sanitary sewage disposal.Production waste bag
Trade effluent, rural sewage and medical sewage etc. are included, and sanitary sewage is exactly the sewage that daily life is produced, and refers to various shapes
The inorganic matter of formula and the complex mixture of organic matter, including：Floating and the size solid particle for suspending；The diffusion of gluey and gel
Thing；Pure solution.
Divide by the property of water pollution, the pollution of water there are two classes：One class is natural pollution；Another kind of is artificial pollution.When
Preceding harm larger water body is artificial pollution.Water pollution can according to pollution impurity difference and be broadly divided into chemical contamination,
Physical pollution and biologic contamination three major types.Pollutant mainly has：First, it is unprocessed and discharge industrial wastewater；2nd, without
The sanitary sewage for processing and discharging；3rd, chemical fertilizer, agricultural chemicals, the farmland sewage of herbicide are largely used；4th, work by the river is stacked
Industry discarded object and house refuse；5th, soil erosion；6th, mine system engineering etc..The method for processing sewage is a lot, can typically conclude
It is Physical, chemical method and bioanalysis etc..
Sewage disposal is sewage is reached a certain water body of draining or the water quality requirement for reusing, and it is purified
Process, can effectively save Water Energy, bring benefit to the mankind, but sewage water treatment method of the prior art and not to the utmost such as people
Meaning, there are problems that investing big, operating cost.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of sewage treatment process, caused in the prior art to solve
Sewage water treatment method is simultaneously not fully up to expectations, there are problems that investing big, operating cost.
To achieve the above object, the present invention provides following technical scheme：A kind of sewage treatment process, including following step
Suddenly：
（1）Filtering：Sewage is collected 20-30min is stirred in treatment tank, side stirring
Side adds sewage-treating agent, is then precipitated, by sewage water filtration after precipitation；
（2）Collect：By step（1）The sewage obtained after middle filtering is collected, and is put into cesspool, then in cesspool
Addition sustained release dephosphorization agent, is reacted, and the reaction time is 20-30min；
（3）Sterilization：By step（2）In the sewage that is collected into be put into sterilization tank, addition chlorine dioxide carries out disinfection.
Preferably, the step（1）The filter screen of middle filtering is 400-800 mesh.
Preferably, the step（1）Middle sewage-treating agent by polymeric aluminium ferrum silicate, foundry loam bactericide,
Hydrogen peroxide, non-phosphate environment-friendly type antisludging agent, inorganic inhibitor and acetic acid composition.
Preferably, the component that the sewage-treating agent is counted by weight：30 parts of polymeric aluminium ferrum silicate, foundry loam bactericide
16th, hydrogen peroxide 20, non-phosphate environment-friendly type antisludging agent 6, inorganic inhibitor 8, acetic acid 20.
Preferably, the step（2）In sustained release dephosphorization agent by 12 hydrazine aluminum sulfate potassium, hydroxypropyl methyl cellulose and
Polyacrylic acid is constituted.
Preferably, the sustained release component counted by weight of dephosphorization agent is：12 hydrazine aluminum sulfate potassium
94 parts, 4 parts of hydroxypropyl methyl cellulose, 2 parts of polyacrylic acid.
It is using technical scheme beneficial effect：By filtering three big processing steps of -- collection -- sterilization, to dirt
Water is processed, and reaches draining or the water quality requirement for reusing, and the process purified to it, can effectively save water
The energy, brings benefit to the mankind, whole processing step advantages of simple, it is easy to control, and will not produce more rubbish, effectively protection ring
Border, cost is relatively low.
Specific embodiment
Below by the description to embodiment, to specific embodiment of the invention such as involved manufacturing process and operation
Application method etc., is described in further detail, to help those skilled in the art to inventive concept of the invention, technical side
Case has more complete, accurate and deep understanding.
Embodiment 1:
A kind of sewage treatment process, comprises the following steps：
（1）Filtering：Sewage is collected 20min is stirred in treatment tank, side stirring
Side adds the component counted by weight：30 parts of polymeric aluminium ferrum silicate, foundry loam bactericide 16, hydrogen peroxide 20, nothing
Phosphorus environment protecting scale inhibitor 6, inorganic inhibitor 8, the sewage-treating agent of the composition of acetic acid 20, are then precipitated, by dirt after precipitation
Water filtration, the filter screen of filtering is 400 mesh；
（2）Collect：By step（1）The sewage obtained after middle filtering is collected, and is put into cesspool
In, the component then counted by weight in cesspool addition is：12 94 parts of hydrazine aluminum sulfate potassium, hydroxypropyl first
4 parts of base cellulose, 2 parts of sustained release dephosphorization agents of sustained release dephosphorization agent composition of polyacrylic acid, is reacted, and the reaction time is 20min；
（3）Sterilization：By step（2）In the sewage that is collected into be put into sterilization tank, addition chlorine dioxide carries out disinfection.
Embodiment 2:
Remaining is same as Example 1, and difference is the step（1）It is middle that sewage is collected in treatment tank
In be stirred 30min, the component counted by weight is added while stirring：30 parts of polymeric aluminium ferrum silicate, foundry loam bactericide 16,
