Description
Technical field
The utility model relates to a kind of sewage disposal device, particularly a kind of membrane-sludge method anaerobic reactor that is used to handle high concentration organic sewage.
Background technology
In the prior art, a lot of to the method for sewage disposal, as chemical oxidization method, flocculation sedimentation, biological chemistry etc., select corresponding treatment process for use at sewage of different nature.The organic sewage that contains high density is often adopted sedimentation in advance or anaerobic treatment,, alleviate the aftertreatment load to cut down organic concentration.The anaerobic biological reactor that is used for anaerobic treatment is many, as up-flow anaerobic sludge blanket (USAB), anaerobic filter (AF), anaerobic baffled reactor (ABR) etc., though up-flow anaerobic sludge blanket and anaerobic filter have certain sewage treatment capacity, but its function singleness, lacking microorganism distributes and the concentration of wastewater Gradient distribution along the journey population, and space availability ratio is not high, and is strong inadequately to the adaptability of various sewage, causes processing power and efficient undesirable; Though anaerobic baffled reactor embodied microorganism along the journey distributivity, improve space availability ratio and to the adaptability of various sewage, and do not needed three-phase separating device, but because it is provided with undesirable, space utilization efficient is not fully exerted yet, influences sewage treatment capacity and efficient.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art and a kind of improved membrane-sludge method anaerobic reactor is provided, and effectively removes the high concentration organic contaminant of sewage, and raising equipment reduces investment and working cost to the processing power and the efficient of sewage.
The purpose of this utility model can realize by following technical measures: this reactor has housing, filler, water inlet pipe is arranged on the housing, rising pipe, be provided with seal cover board in the housing upper port, be laid with the baffling dividing plate in the housing, last baffling dividing plate is separated at least two reaction tanks with housing, all be provided with down the baffling dividing plate in each reaction tank, the upper end of last baffling dividing plate is a water outlet, the lower end is connected on the base plate of housing, the lower end of following baffling dividing plate is a water outlet, the upper end is higher than the upper end of baffling dividing plate, on, following baffling dividing plate two side ends is connected to the inwall of housing, on, the water outlet of following baffling dividing plate forms the baffling structure that misplaces up and down; The bottom of reaction tank is the anaerobic activated sludge district, and anaerobic activated sludge has active sludge in the district, and filler is seated in the middle and upper part of reaction tank, is fixed by upper and lower baffling dividing plate, forms the collecting methane chamber between cover plate and the filler, on the cover board is provided with the collecting methane pipe.
High concentration organic sewage enters in the housing from water inlet pipe, in each reaction tank, all pass through the active sludge in carrier filler and anaerobic activated sludge district, water outlet baffling on upper and lower baffling dividing plate, when upwards flowing, contact with the anaerobic sludge in anaerobic activated sludge district earlier, flow through filler again, fully contact with filler; It is then just opposite to flow downward, sewage flows through filler earlier and fully contacts with filler, entering the anaerobic activated sludge district again contacts with the active sludge mixing, respectively via the staggered effect of microbial film on the filler and active sludge, high-enriched organics generation anaerobic methaneization or hydrolysis reaction, the biogas that the anaerobic reaction process produces can be collected by the collecting methane chamber and recycle through the collecting methane pipe, because the mud of its generation is few, but self complete digestion is handled, do not need spoil disposal, after sewage in the reactor obtains effective anaerobic treatment, discharge through rising pipe.
The utility model is reasonable in design, utilize the staggered effect of filler and active sludge, make biomembrance process and activated sludge process, the microorganism that had both guaranteed the active sludge district distributes along the journey population, make again along Cheng Chengxian concentration of wastewater Gradient distribution simultaneously, make each reaction tank bring into play its reactivity worth effectively, increased shock-resistant ability, improved space availability ratio and the adaptability of various sewage disposals, shorten the reaction times effectively, have the effect that classification cycle is handled, it is simple in structure, and floor space is little, working cost is low, processing power and efficient height, adaptability is strong, is the environmental protecting device of Nover practical.
