Description
Technical field
The present invention relates to a kind of sewage disposal system and method, particularly a kind of solar rural domestic sewage drips filter and processes
System and using method thereof, belong to life in the countryside sanitary sewage disposal field.
Background technology
In recent years, China's rural economic construction high speed development, the level of urbanization improves constantly, but domestic sewage in rural areas discharge
Amount is consequently increased, and water pollution situation also runs down, and Rural Water Environment pollution problem is more and more prominent.Life in the countryside disperses
The main feature of formula sewage has and has water yield minor swing greatly, and in sewage, the content of nitrogen and phosphorous is high, easily causes the eutrophication of water body.
At present, common rural dispersed domestic sewage processing method is mainly with anaerobic bio-treated, bio-contact oxidation
Process, land treatment systems, artificial swamp etc. or treatment technologies that wherein both or both combine above.But such as anaerobism+aerobic+wet
Ground method, it is big to there is energy consumption in this method, and effluent quality effect is unstable, and the shortcoming such as Nitrogen/Phosphorus Removal is limited.It addition, MBR/ is artificial
Wet land technique, with advantages such as its high sludge concentration, stable effluent quality, also has very in the field of decentralized wastewater process and reuse
Good competitiveness, but its high operating cost limits its extensive application.
Trickling filter is also known as biofilter, and in trickling filter, sewage purification process includes the mass transport process of sewage, the diffusion of oxygen is inhaled
Receive, the various processes such as the metabolism of organic decomposition and microorganism, its cardinal principle is sewage when flowing through trickling filter, filler
Suspended material in trap water, absorbs colloid and dissolved matter.Microorganism simultaneously utilizes Organic substance and the nutrient substance of absorption,
Filler shows growth and breeding, and the content of organics in sewage greatly reduces, and water quality is purified.Trickling filter applies in general to process
Day, sewage quantity was less than 1000m3,And the Small Town Wastewater of relative distribution or country sewage, its major advantage is: be easily managed, and saves
The energy, stable, surplus sludge volume is few and is prone to settle decomposition etc..
Artificial wet land treating system, utilizes physics sedimentation, root system of plant obstruction, microbial metabolism, soil and plant surface
Absorption Absorption, remove oil removal, organic substance, and nitrogen and phosphorus had certain removal effect.Its advantage has expenditure of construction
Saving, operating cost is low, it is easy to maintenance technology content is low, processes reliable, and effluent quality is good, is widely used at country sewage
Reason.
Summary of the invention
The technical issues that need to address of the present invention are for above-mentioned the deficiencies in the prior art, and provide a kind of low energy consumption, fortune
Row convenient management, economy and beautiful appearance, sewage treating efficiency is high simultaneously, the environmentally friendly solar rural domestic of stable effluent quality
Sewage drips filter processing system and using method thereof.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of solar rural domestic sewage drips filter processing system, including the grid regulating reservoir being sequentially connected with by water pipe, trickling filter,

Have effusion meter well, elevator pump to have pipeline with effusion meter well to be connected；Include in described trickling filter setting gradually a high position from top to bottom
Water tank, water distribution pipe, packing layer, supporting layer and the layer that is filled with water, arrange ventilation duct in the layer that is filled with water, ventilation duct is distributed in the pond of trickling filter
On wall, effusion meter well communicates with elevated tank；Described artificial swamp includes inhalant region, treatment region and the exhalant region communicated, water inlet
District's internal upper part is inhalant region haydite floor, and bottom is inhalant region gravel layer, be followed successively by from top to bottom in treatment region treatment region coarse sands layer,
Treatment region gravel layer, modified lime stone haydite layer and treatment region bottom gravel layer, exhalant region internal upper part is exhalant region upper strata gravel
Layer, bottom is exhalant region lower floor gravel layer, and the layer that is filled with water communicates with inhalant region, and exhalant region is provided with outlet pipe.
As further preferred version, in described treatment region, it is provided with perforation tracery wall, treatment region coarse sands layer has and plants
Tegillum.
As further preferred version, described grid regulating reservoir, trickling filter, the volume ratio of artificial swamp are 1:1.2-
1.8:11-11.4。
As further preferred version, between described trickling filter and grid regulating reservoir, it is additionally provided with return duct, described
The layer that is filled with water of one connection trickling filter of return duct.
As further preferred version, described grid regulating reservoir is outside equipped with the solar panels powered for elevator pump,
Solar panels are mono-crystalline silicon solar electroplax.
As further preferred version, described packing layer is Pumex layer.
As further preferred version, the hole of described perforation tracery wall is evenly distributed, and its aperture is 100mmX100mm,
Adjacent two hole center distance 200mm.
As further preferred version, the laying depth of described inhalant region haydite layer is 225mm, haydite grain therein
