Description
Technical field
The invention belongs to water environment pollution and Treatment process field, relate to a kind of rural scattered domestic sewage treatment device
And method.
Background technology
Along with small towns, developing rapidly of rural area and improving rapidly and living condition bright of vast rural area living standards of the people
Aobvious improvement, the discharge capacity of domestic sewage in rural areas is continuously increased.Due to the shortage of the long-range environmental planning in rural area, rural area drainer
Cheng Yizhi is out in the cold, and the Sewage Treatment Facilities of major part rural area is still far from perfect, and causes major part life in the countryside dirty
Water pollution problems can not get solving.The Ministry of Construction's " village human settlement's present situation and problem " investigation report shows: the village of 96% does not has
There are discharge conduit and sewage disposal system, productive life sewage arbitrarily to discharge, thereby result in rural rivers and generally polluted, also
Serious threat is to subsoil water, and the phreatic water even having has been polluted, it is impossible to take.
The feature of domestic sewage in rural areas water quality is that the content of nitrogen and phosphorous is high, biodegradability is strong, containing poisonous and harmful substances such as heavy metals
Less；Having each household discharge capacity in discharge less, water quality and quantity fluctuation is relatively big, and emission point disperses, and collects the features such as more difficult；
And contained pathogen is more in feces.In addition, China's rural population inhabitation ratio is relatively decentralized, and existing sewage disposal small scale makes
Expense for construction, operating cost are higher, and sewage treatment facility is the most easily affected by local natural environment so that China's country sewage
Treatment technology is selected and process parameters design is different from city domestic sewage and processes, and dimension is bigger.Rural domestic sewage treatment
The select country practical situation technology with it is critical only that treatment in accordance with local conditions of effect quality, can not only reach discharging standards, more
It is important that meet the requirements such as investment is little, operational management is convenient, develop low cost, miniaturization, integrated form, low cost, nature
Processing system group technologies etc. are very urgent and necessary.Therefore, based on existing various sewage disposal technology advantages and defect point
Analysis, filters out applicable technology for treating domestic sewage in rural area the most crucial, significant.Therefore, the present invention is by anaerobic filter, life
The technology such as state chinampa, wetland are optimized combination, process rural area decentralized type sewage, to human settlement's improvement, society master
Justice new countryside construction has highly important real value.
Summary of the invention
