Description
Technical field the invention belongs to field of environment protection; belong to a kind of organism that the organism anaerobic hydrolysis of the organism of the macromolecular chain in the high-concentration sewage and difficult for biological degradation can be become micromolecular organism and readily biodegradable, be convenient to subsequently the further speed change flow lifting type anaerobic treatment method of biological treatment.
In the prior art, the treatment process that adopts anaerobic process to handle high-concentration sewage has two kinds to background technology at home.First kind is adopted anaerobic methane stage processing sewage, and this method can be innoxious substances such as methane, carbonic acid gas with the organic substance anaerobic digestion in the sewage, but the dwell time of sewage of this treatment process is long, and bulky, floor space is big, the investment waste; Second kind is adopted the anaerobic hydrolysis of solid, liquid, gas triphase separator to dispose of sewage, this method can be decomposed into the organism in the sewage small organic molecules such as formic acid, acetate, the dwell time of sewage of this treatment process is short, floor space is little, but the design of required triphase separator is complicated, difficulty is installed, inferior separating effect, cost height.At present domestic quantity of wastewater effluent increases day by day, directly exhaust emission river, river, lake, the processing of sewage causes that day by day people pay attention to, and operation is simple, floor space is little, cost is low, the high-concentration sewage anaerobic treatment method of good separating effect yet there are no report.
Summary of the invention is big for the floor space that overcomes anaerobic treatment high-concentration sewage in the prior art, and the investment waste is installed difficulty, the deficiency that cost is high.Goal of the invention of the present invention is that a kind of floor space of design is little, and treatment effect is good, and is easy for installation, moves simple speed change flow lifting type anaerobic treatment method and handles high-concentration sewage.The method of the different anaerobic methane stage processing of speed change flow lifting type anaerobic treatment method sewage, the treatment stage that adopting anaerobic hydrolysis, this method handles high-concentration sewage, the solid, liquid, gas triphase separator of complexity is designed to simple speed change up-flow inclined tube-type solid, liquid, gas separation method treatment stage of with anaerobic hydrolysis, inclined tube adopts glass reinforced plastic or plastics impregnating material, can carry out the bonding arbitrary shape that is assembled at the scene, design and installation is convenient.Speed change flow lifting type anaerobic treatment method also is designed to the treating processes in anaerobic methane stage the treating processes in the residence time in short anaerobic hydrolysis stage, and speed change flow lifting type anaerobic treatment method floor space is little, and running cost is low.
The technical solution adopted for the present invention to solve the technical problems is: the principle of design of speed change flow lifting type anaerobic treatment method is that processing of anerobic sowage hydrolytic purification and mud concentrating return-flow are integrated, sewage enters in the device of speed change flow lifting type anaerobic treatment method from the inlet that adopts the porous water distribution manner, the orifice diameter of porous water distribution is at 5-100mm, the aperture direction is towards the below or tiltedly, the sewage uniformly distributing that enters is upwards flowed, and flows through the mud district.Active granule sludge bacterial classification floor is housed in the mud district, produces micro-bubble when the pollutent of granule sludge bacterial classification in can degradation of sewage, pollutent in degradation of sewage, slowly rising behind the granule sludge bacterial classification that adheres to micro-bubble and the sewage thorough mixing.Speed change up-flow inclined tube separator is equipped with on top at device, the basal area of the bottom of speed change up-flow inclined tube separator is smaller, the basal area on top is big, flow velocity when effluent stream is crossed speed change up-flow inclined tube separator like this is along with the flow velocity of the variation sewage of basal area also changes, the flow velocity of sewage from large to small, with sewage together upwards mobile granule sludge bacterial classification because diminishing of flow velocity and and water sepn, granule sludge bacterial classification precipitation downwards under action of gravity.Because the speed change up-flow inclined tube distance each other that adopts is less, generally between the 60-100 millimeter, less distance makes sedimentary granule sludge bacterial classification sink to the bottom of inclined tube very soon and to lower slip, separates with sewage.The granule sludge bacterial classification that adheres to bubble is when running into the upper wall of inclined tube, slight vibrations made bubble and granule sludge strain separating when utilization was collided, bubble moves upward along the upper wall of inclined tube, with the granule sludge strain separating, the granule sludge that breaks away from bubble also can sink, and sinks to the bottom of inclined tube very soon and to lower slip.The gas that this method produces in the time of can separating sewage, granule sludge bacterial classification and granule sludge strain degradation sewage effectively, granule sludge bacterial classification after the separation glides along inclined tube and reenters granule sludge bacterial classification layer, thereby kept a large amount of granule sludge bacterial classifications, gas after the separation rises to the water surface along the inclined tube upper wall and overflows, and the sewage discharger after separating.Speed change flow lifting type anaerobic treatment method keeps the granule sludge bacterial classification of high density by speed change up-flow inclined tube separator, the sewage short period of time stop in anaerobic hydrolysis stage is changed in the long-time stop of the sewage in anaerobic methane stage, thereby reduced device volume and cost greatly.
The invention has the beneficial effects as follows that this method adopts simple speed change up-flow inclined tube separator to replace complicated triphase separator, speed change up-flow inclined tube separator adopts corrosion resistant glass reinforced plastic and plastics to make, can batch production produce in batches, and field assembly, method is simple.
