Background technology
At present due to life, the sewage producing formation, the destruction for water surrounding has arrived the instant protection moment.Rural area, the sanitary sewage of town region people, ight soil, existing traditional processing mode is mostly the process such as anaerobically fermenting, precipitation means, need the cement manure pit of a construction leakproof, not only man-hour is long, cost is large, and occur that work-ing life is not long along with problems such as sedimentations, often causing revealing affects groundwater quality.This existing process means its cannot accomplish the beneficial effects such as in line, the useless solid second stage employ of solid-liquid separation, waste liquid.Usually use in existing Sewage treatment systems in addition and carry out biofilm containing the filler of microorganism and to purify water process, but there is obvious technological deficiency in this kind of process means, namely the survival of microorganism has strict requirement for envrionment temperature, in existing treatment system, its installation must distinguish region, just northern cold region can not be used in as some microbe treatment system, also microflora can be caused southern winter in time dead, and affect the normal use for the treatment of facility.How to design a kind of construct simply there is in line, useless solid full-time of second stage employ of solid-liquid separation, waste liquid, the efficient rural sewage treatment system of region is the object that those skilled in the art study always.
Chinese invention patent application numbers 201410294304.3 discloses a kind of single injection-molded septic tank, comprises main body, and main body is one overall by two halves casing by bolt tightening.A grid septic tank dividing plate and two grid septic tank dividing plates are established in aforementioned body.Two grid septic tanks are formed between one grid septic tank dividing plate and two grid septic tank dividing plates; A grid septic tank is formed between one grid septic tank dividing plate and septic tank body; Three-grid septic tank is formed between two grid septic tank dividing plates and septic tank body.The technical clarification of this kind of in line about waste liquid and the infull Time Domain Processing of three-grid septic tank or solution.
Summary of the invention
The invention provides a kind of construct simply have that solid-liquid separation, waste liquid are in line, space, region apply wide efficient country sewage refining plant.
A kind of efficient country sewage refining plant, comprise and to be reeled the cylinder formed by sheet material, the airtight connection in cylinder two ends is respectively equipped with the end cap of waste pipe and outlet pipe, be divided into three regions by two dividing plates in cylinder, three described regions are followed successively by anaerobic fermentation zone, biochemical treatment district, sedimentation and drawing district.
Described anaerobic fermentation zone comprises the siphon trap head connecting waste pipe; Siphon trap header structure changes its first lattice of the waste disposal plants such as traditional three-grid septic tank necessarily by the aerobic zone of inlet communication air, this kind of good oxide structure is unfavorable for the generation of anaerobically fermenting environment, the present invention is by the cylinder area formation anaerobic fermentation zone of siphon trap structure at connection waste pipe, by airtight anaerobic environment, form anaerobically fermenting, can decomposing protein organism, and produce the material such as biogas, ammonia, parasitic ovum and germ are carried out first time and kills.
Described biochemical treatment district comprises the chain filler of the hollow expansion link of spiral winding, the hollow expansion link body of rod is provided with breather hole, breather hole is embedded with carbon pipe, utilize the vesicular structure amount reproduction microorganism of carbon pipe, composite flora is provided with in the body of rod, the expansion link body of rod of hollow structure not only can as the oxygen sources passage of this kind of aerobic bacteria of composite flora, and the passage that also can add as composite flora secondary substantially increases the convenience of use.Chain filler not only prevents from occurring between adjacent filler to be wound around the filler premature failure caused by the hollow expansion link of spiral winding, and the upper degree of depth is controlled under this kind of hollow expansion link, the variation water quality of water is disperseed fully, cut down rapidly again simultaneously, thus improve the capacity of resisting impact load of system.Biochemical treatment district also comprises the header being located at barrel top, the distributive pipe being located at bottom of cylinder, be communicated with by the heat pipe of more than two between header and distributive pipe, distributive pipe feed-water end is communicated with earth source heat pump, the heat of earth source heat pump sorption enhanced is utilized to evenly spread in heat pipe by distributive pipe, thus keep the treatment temp in biochemical treatment district, guarantee the activity of composite flora and good reproductive status, realize the technical purpose of efficient sewerage processing.Earth source heat pump increases the round-the-clock and full regional characteristic that treatment temp is not subject to the time, the restriction in space achieves use range of the present invention in biochemical treatment district.
Chain filler composition is polyvinyl chloride, bamboo fibers, elm bark powder mixture, and preferred weight percent composition is: 80-90% polyvinyl chloride, 5-10% bamboo fibers, 5-10% elm bark powder.Elm bark powder has natural plant viscosity can realize biofilm rapidly, substantially increases clean water performance.The micropore formed after elm bark powder corrosion further increases voidage and the specific surface area of filler, and pole is beneficial to the growth of composite flora, thus reaches very high purification efficiency.
Described composite flora comprises bacillus, nitrobacteria, Decolourization Bacteria, yeast, milk-acid bacteria.Nitrobacteria is the important component of the pollutents such as process C0D, but often being eliminated by harmful bacteria because its reproduction speed is slow causes flora effective constituent to disappear, and the present invention is by reproduction speed aerobic yeast quickly, is responsible for robbing domain to nitrobacteria and breeds; Another one is the milk-acid bacteria of anaerobism, and reproduction speed also quickly, is responsible for eliminating bacterial classification that low-oxygen area is harmful to nitrifier thus substantially increases the surviving rate of composite flora and the clearance for pollutent.
Described header forms skeleton construction with distributive pipe by being connected heat pipe, a hollow expansion link is embedded between adjacent two heat pipes, flora, the microorganism of guaranteeing to be attached to hollow expansion link and chain filler periphery obtain the good temperature environment of an activation, are convenient to amount reproduction and pollutent biofilm.
Two described dividing plates are equipped with overflow weir, separate the dividing plate overflow weir in biochemical treatment district and sedimentation and drawing district higher than the dividing plate overflow weir separating biochemical treatment district and anaerobic fermentation zone.Guarantee the anaerobic environment of anaerobic fermentation zone and the aerobic environment in biochemical treatment district further, certainly also make sedimentation and drawing district obtain higher liquid level and improve the effect precipitated.
The cylinder at top, described biochemical treatment district is provided with ventilation inclined hole, utilizes inclined hole structure to form the convection of air environment tilted and makes more composite flora touch fresh air.
The present invention by septic tank being separated into anaerobic fermentation zone, biochemical treatment district, region, three, sedimentation and drawing district achieve ight soil, sewage, the technical purpose that solid-liquid separation, waste liquid are in line, the treatment temp simultaneously adopting heat source pump technology to increase biochemical treatment district reaches the round-the-clock and full regional characteristic of native system.Only need cylinder to insert about construction and installation in the hole dug, very convenient.
