Background technology
Along with developing rapidly of small towns, rural area, population is lived and is concentrated day by day, the quantity discharged of domestic sewage in rural areas by using constantly increases, many small towns begin to build sewage work, yet a little less than the town government ability to shoulder economically, maintenance management technician operational management experience famine, the treatment process that most of small towns do not adapt with it.
In the area of municipal sewage pipe network no show, the residential quarters sanitary sewage disposal also is the problem that is difficult to solution always.According to incompletely statistics, the pollutent of sanitary sewage has accounted for water pollutant total amount 40%~50% in the city.Because the urban groundwater road sewage collection system of China is not perfect, sewage work's fraction of coverage is lower and the numerous not treated just directly dischargings of sanitary sewage that can't take over the biotope in area of causing cause the more serious problem of environmental pollution.And there are shortcomings such as expense for construction and running cost height, maintenance management personnel experience shortage simultaneously again in characteristics such as samll cities and towns and residential quarters sewage disposal have small scale, the water yield, change of water quality is big, alternative technology is few.
Therefore, for above place disperse, the less population center of quantity of wastewater effluent, should design that a kind of equipment is simple, investment and working cost is few, stability high and be easy to maintenance management unpowered water technology sanitary sewage purified on the spot and carry out recycle.
Summary of the invention
The purpose of this utility model is to provide that a kind of energy consumption is low, treatment effect good, safeguard simple unpowered domestic sewage processing system at middle-size and small-size sanitary sewage.
For achieving the above object, the utility model is by the following technical solutions:
A kind of unpowered domestic sewage processing system, it comprises successively grid settling tank, anaerobic digester, anaerobic biofilter, oxygen compatibility pool and the honeycomb inclined-plate clarifying basin that connects by from high to low, all is arranged on underground with upper pool body.
Grid settling tank described in the such scheme is provided with two of grid and settling regions, the effect of play and hold back the bulk solid suspended impurity, removing chiltern in the sewage, and hydraulic detention time is 3~6h, the grizzly bar gap of grid is 10-40mm.
Anaerobic digester described in the such scheme mainly plays acidication, enter anaerobic digester through the preliminary sanitary sewage that filters of grid, foreign material such as ight soil, paper are deposited in the anaerobic pond bottom, the organism that precipitates hydrolysis under the effect of acidity corruption bacterium or acid-producing bacteria, acidifying, hydraulic detention time is 16-24h.
The bio-matrix floating stuffing has been filled in anaerobic biofilter inside described in the such scheme, bio-matrix chemistry and biology good stability, specific surface area is big, high adsorption capacity, porosity height, and biofilm is easy, the bio-matrix dispersion suspension is in the biological filter, packing volume is 1/100-1/20, and the adding of bio-matrix has increased biomass and the corresponding COD rate of load condensate of biological filter; Anaerobic filter arranges traverse baffle simultaneously, anaerobic zone is divided into a plurality of compartments, processed waste water being flowing in of each compartment and water of flowing through successively goes to upper and lower alternate run in the reaction tank, make the biodegradation process that is carrying out having the biological organic substrate that participates in of different floras in each compartment, impelled stable, the efficient operation of total system, the hydraulic detention time of anaerobic biofilter is 24-36h.
The important function of the oxygen compatibility pool described in the such scheme is to remove NH 3-N concentration is provided with ventilation plant on this regional top, makes it to communicate with air and form certain convection current; Hang elastic solid filler and fixing flora in the body of pond, sewage is further removed organic pollutant under the acting in conjunction of aerobic area difference floras, and the hydraulic detention time of aerobic area is 12~24 h.
Many intensive cellular swash plates are set in the honeycomb inclined-plate clarifying basin described in the such scheme, make that suspended impurity precipitates in the water in swash plate, water rises along swash plate and flows, the sedimentation under action of gravity of isolated body refuse, the inclination angle that the honeycomb swash plate is set is 50 °-60 °, length is 800-1000mm, and the swash plate spacing is 25-30mm.
The beneficial effect that the utility model reaches is:
1, adopt unpowered domestic sewage processing system of the present utility model, need not to arrange power-equipments such as water pump, blower fan, do not consume energy, construction costs is cheap, and technology is simple, and operational management is convenient, satisfies the processing requirements of middle-size and small-size sanitary sewage project.
2, adopt the novel biochemical treatment process, at first take full advantage of hydrolysis-souring stage and realize organic efficient degradation, further degrade by the treatment process of anaerobism and the oxygen of holding concurrently then and remove organism and ammonia nitrogen etc., effluent quality height, water conditioning, discharging or reuse requirement can be up to state standards.
3, adopt new bio matrix floating stuffing and rational flap flow guide system, guaranteed stablizing, efficiently moving and the anti impulsion load ability of total system.
4, surface-area is not taken up an area of in buried setting, can integrated enforcement be built in sewage disposal and greenery patches according to the greening needs.
5, handle for cities and towns and domestic sewage in rural areas by using and realize that sewage recycling and water resources sustainable utilization provide a kind of new way, for town and country construction and energy-saving and emission-reduction work provide a new technical support.
