Description
Technical field
The present invention relates to a kind of sanitary wastewater processing methods, belong to technical field of waste water processing.
Background technique
Existing lavatory (toilet) has more functions, clothes of such as having a bath, wash one's hands or do washing, it should be noted that one
Point, it is closely bound up with water for no matter carrying out which kind of activity in the bathroom, and then has a large amount of sewage and generate.It is existing
Toilet in the sewage that generates be directly to be discharged in sewer by pipeline, not only cause a large amount of of water resource in this way
Waste, new challenge is also proposed to the ability to bear of downcomer；More importantly the change that the sewage in sewer carries
It learns substance and damage difficult to the appraisal often is caused to environment.
Contain a large amount of pollutant in sanitary wastewater, and the smell is awful, if direct emission will affect environment, in rural area lavatory
Institute's sewage can be used for the fertilising of crops, but in city, sanitary wastewater discharge has to reach discharge standard by processing
After can discharge, feces of toilet sewage because its biodegradability height, in the prior art, at the beginning of UNITANK is the last century 90's
Start application sewage treatment process, the technology combine SBR, traditional activated sludge process, three working position method it is excellent
Point overcomes SBR intermittent water inflow, and the land occupation of three ditch formulas is big, the disadvantage more than Traditional Method equipment.The technique is once proposition just by the industry
Favor, but due to the technique automatic control in terms of requirement it is relatively high, there is no application in this small-sized processing system of sanitary wastewater.
Currently, the processing method to sanitary wastewater mainly uses microbial method to handle it.But microbial method exists
The problem of limit it in the application of some special dimensions.There are the problem of have: using microbial method processing sanitary wastewater dress
It sets and is unable to plug and play, microorganism needs the culture that professional carries out 3-14 days time, dirty before microculture completion
Water is unable to qualified discharge；Device intermittent duty using microbial method processing sanitary wastewater is inconvenient, period out of service, micro- life
Object, which needs nutrients, maintains activity；Treatment process cannot eliminate the stink of sanitary wastewater, and easily breed mosquitos and flies, generate hygienic issues；
And all there are the following problems for nearly all strain currently in use at present: microorganism fungus kind is single, and composite flora is few；Microorganism
Activity is low, and power of regeneration is weak, needs to be continuously replenished；Adaptation low for indoles mass degradation power in excrement, to inorganic salts
Property difference etc..So many places handle sewage nearby, then by treated, sewage is directly discharged into neighbouring rivers, lake
In, processing mode is simple, and treated, and sewage is difficult to reach discharge standard, and long-term discharge will lead to water PH value, COD content mistake
Height, destroys the biobalance of water ecosystem, and will cause water eutrophication, therefore is badly in need of a kind of sanitary wastewater processing side
Method, it is present to solve the problems, such as.
Summary of the invention
The technical problems to be solved by the invention: for current sanitary wastewater, treated that sewage is difficult to reaches discharge mark
Standard, long-term discharge will lead to water pH value, COD too high levels, destroy water body, and will cause that water eutrophication is excessively high to ask
