Description
Technical field
The invention belongs to surface water pollution water body processing technology field, more particularly, to a kind of based on photovoltaic driving
Sewage disposal system and processing method and application.
Background technology
In China wast rural area, with the fast development of working condition being obviously improved with rural economy, people’s lives
Significant changes occur for mode, and living standard also greatly improves, however, people, while pursuing high-quality life, some are lived
Mode also brings serious threat to the ecological environment in rural area, and waste has become locality caused by some local people's lives
One of main pollutant.Such as being widely used for washing machine, bath in a tub becomes taking a shower, and dry pail latrine is changed to toilet flushing etc., these are high-quality
While amount life style allows people to enjoy good life, a large amount of sanitary sewage is also produced.Since village disperses, house
Draining is not yet formed with sewage treatment facility, cause the sewage that villager is discharged it is unprocessed be just directly discharged to it is neighbouring small
In small stream, pond, river, if long-term discharge wantonly is administered not in time again, by the local ecological environment of serious pollution, or even threaten
The drinking water safety of villager largely effects on the look of a village village looks construction to new socialist countryside, also counteracts rural strategy to revitalize
Implementation.For that purpose it is necessary to be administered to the sanitary sewage increasingly discharged.
Currently, management means and engineering measure is mainly taken to be resolved for the sanitary sewage of rural area discharge.Management
Means advocate using water wisely, cycling use of water mainly in conjunction with the implementation of building Socialist New and rural strategy to revitalize
Environmental consciousness reduces the discharge of sewage from source.Engineering measure mainly takes technological measure to be administered to sewage, is
Most effective way, common processing mode have centralization and two kinds of improvement forms of distributing.However, coming to the vast rural areas
It says, since village is numerous, distribution is scattered, and input improvement funds are limited in addition, it is difficult to which sewage disposal that is newly-built, promoting centralization is set
It applies.Therefore, decentralized type sewage treatment technology has become rural sewage treatment main means in some places and has caused environmentally friendly work
The concern of author.Currently, traditional decentralized type sewage processing has oxidation pond, septic tank, land treatment system.Oxidation pond is to organic
The removal of object and nitrogen is limited and processing time is longer, and operation is bad to influence look of a village village looks；Septic tank, frequently as sewage disinfection treatment
System, water outlet still suspended matter, BOD with higher concentration5, nitrogen, phosphorus and pathogenic bacteria, water body cannot be directly discharged into, therefore cannot
It is used alone；Artificial wet land system is the novel ecological system simulated land treatment system principle and formed, and passes through matrix, plant
And microorganism collaboration, carry out the pollutant in degradation water through physics, chemistry and biological effect, small investment, operating cost are low, can be compared with
It goes well to denitrogenate, phosphorus, however processing speed is slow, apparent by seasonal effect, operation is improper can cause underground water pollution.In addition, knot
The water quality characteristics of sanitary sewage are closed, common processing unit (such as flocculation treatment unit) works well in some centralized techniques,
It is very suitable for administering the sanitary sewage of rural area discharge, however operating cost constrains the use of these processing units, explores thus
It is always environmental worker's focus of attention to be suitble to rural area distributing household domestic sewage treating method also.
