Description

A kind of domestic sewage treatment process
Technical field
The invention belongs to sanitary sewage disposal technical field, more particularly to a kind of domestic 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 sewage treatment and sanitary sewage disposal.Production waste bag Trade effluent, rural sewage and medical sewage etc. are included, and sanitary sewage is exactly sewage caused by daily life, refers to various shapes The inorganic matter of formula and the complex mixture of organic matter, including：Floating and the size solid particle to suspend；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 kind is natural pollution；Another kind of is artificial pollution.When Preceding endanger 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, unprocessed and discharge industrial wastewater；2nd, without The sanitary sewage for handling and discharging；3rd, largely using chemical fertilizer, agricultural chemicals, the farmland sewage of herbicide；4th, work by the river is stacked Industry discarded object and house refuse；5th, soil erosion；6th, mine system engineering etc..The method for handling sewage is a lot, can typically conclude For Physical, chemical method and bioanalysis etc..
Sanitary sewage disposal is sewage is reached a certain water body of draining or the water quality requirement reused, and it is carried out only The process of change, Water Energy can be effectively saved, is brought benefit to the mankind, but sewage water treatment method of the prior art and not to the utmost such as People's will, traditional sanitary sewage are directly outer row mostly, cause serious water resource.
The content of the invention
The invention aims to solve shortcoming present in prior art, and a kind of sanitary sewage disposal work proposed Skill.
To achieve the above object, the present invention provides following technical scheme：
A kind of domestic sewage treatment process, comprises the following steps：

S2, sedimentation basin top clarified solution converged in collecting-tank, be stirred 20-30min, add sewage while stirring Inorganic agent, and add oxidant, flocculation aid and flocculant into collecting-tank and sewage is sterilized and causes the charged particle in sewage Solidification forms floccule；
S3, then the sanitary sewage obtained in S2 is precipitated, by sewage water filtration after precipitation, filter out sanitary sewage In residue and floccule, the sewage obtained after filtering is collected, is put into cesspool, is then removed in cesspool addition sustained release Phosphorus agent, is reacted, reaction time 20-30min；
S4, by S3 handle after sewage collecting to sewage be put into sterilization tank in, addition chlorine dioxide disappeared Poison；
S5, the sewage after being handled in S4 is filtered, the sewage after filtering enters Desultwater Station via water station, in desalination Water station is by filtering the solid impurity, colloid, larger molecular organicses and the salt ion that are eliminated with counter-infiltration in sewage, by processing Qualified product water, which is delivered to, each uses water spot；
S6 and then the sewage discharged from the Desultwater Station solid impurity in filter sewage again, now, first pass around sky Gas Air-float separator changes the COD of sewage, and it is miscellaneous to be then passed through integrated water purifier, ultra filtration device and RO counter-osmosis devices removal solid Matter, colloid, larger molecular organicses and salt ion, handle qualified product water and just flow back in water station and recycle.
Preferably, sedimentation basin weekly twice, each spoil disposal half an hour, arrange spoil disposal daily by efficient sedimentation tank in the step S1 Mud half an hour, odd-numbered day row's odd numbers pond, even-numbered days row's even numbers pond.
Preferably, the sewage-treating agent in the step S2 is by polymeric aluminium ferrum silicate, foundry loam bactericide, hydrogen peroxide, nothing Phosphorus environment protecting scale inhibitor, inorganic inhibitor and acetic acid composition.
Preferably, the filter screen of filtering is 400-800 mesh in the step S5.
Preferably, the sustained release dephosphorization agent in the step S3 by 12 hydrazine aluminum sulfate potassium, hydroxypropyl methyl cellulose and Polyacrylic acid forms.
Preferably, the chemical sludge in the step S1 in sludge concentration tank crosses sludge concentration tank all, reaches plate and takes off Behind water dispenser room, it is pressed into mud cake and carries out outward transport processing.
The technique effect and advantage of the present invention：A kind of domestic sewage treatment process provided by the invention, with conventional art phase Than by filtering, collecting and sterilizing three big processing steps, handling sewage, the water quality for reaching draining or reusing will Ask, the impurity in sewage and high salinity can be efficiently separated, it is fully obtained cycle applications, it is therefore prevented that production waste pair The influence of environment, realizes zero-emission；And the process purified to it, Water Energy can be effectively saved, is brought benefit to the mankind, it is whole Individual processing step advantages of simple, it is easily controllable, more rubbish will not be produced, effectively environmental protection, cost is relatively low.
