Description
Technical field
The present invention relates to technical field of sewage, especially relate to a kind of biology and drip bed.
Background technology
Dirty water living creature processing technique is through 100 years of development, the form that exists of the microorganism that degradation of contaminant is played a major role mainly is divided into two classes, one class is to be discrete type, the flocculu shape of representative with the Activated Sludge Process, and an other class is to be that the microbial film of representative exists form with technologies such as biological filter and blodiscs.Microorganism exists with the microbial film form, can improve waste disposal plant unit volume microorganism concn, thereby effectively increases the treatment unit volumetric loading, improves processing power, strengthens capacity of resisting impact load.
At present, the microbial film sewage disposal technology mainly comprises aerobic contact oxidation, BAF, blodisc and biological filter etc.The microbial film that aerobic contact oxidation (as: number of patent application CN201020237578.6) and BAF (as: patent ZL02129618.9) all are attached to carrier is immersed in the sewage, need to rely on mechanical blast aeration to satisfy the demand of microorganism to oxygen, the energy consumption height, in service can the obstruction needs back flushing.Blodisc technology (as: number of patent application CN201010235846.5), microorganism growth is in the blodisc disc surfaces, rely on the disk body mechanical rotation, microorganism alternately is in the air and sewage in, guaranteed the microorganism oxygen supply, this process machinery equipment complexity, disc surfaces is long-pending little, and processing power is lower.Bio-trickling filter relies on the nature oxygen supply to satisfy the demand of microorganism to oxygen, patent CN200710170419.1 overcomes the treatment effect that exists in the prior art effectively and is subjected to shortcomings such as hydraulic load influences greatly, the easy obstruction in filter tank, but the high-rate filter of the back flushing of exploitation.
Mentioned microorganism is with the sewage treatment process that the microbial film form exists, and the needs that have rely on mechanical blast aeration to satisfy the demand of microorganism to oxygen, the energy consumption height; The mechanical means complexity that has, disc surfaces is long-pending little, and processing power is lower; What have needs back flushing for avoiding stopping up.The existence of this type of problem all impacts sewage treatment process management and energy consumption.
Summary of the invention
Purpose of the present invention be exactly provide a kind of complete modularization in order to overcome the defective that above-mentioned prior art exists, optimized structure, biology easy to use drips bed.
Purpose of the present invention can be achieved through the following technical solutions:
A kind of biology drips bed, it is characterized in that, this biology drips bed and is made of suction culvert, water distribution system, filler module and outlet system, described suction culvert and water distribution system are located at top, and water inlet is evenly distributed in the filler module, and described filler module edge is vertically to setting, top filler module is done support with bottom filler module, need not to be provided with separately bracing frame, described outlet system is located at foot, collection, backflow and emission treatment water.
Described filler module is that rigid plastics, glass reinforced plastic or light-weight metal sheet material are made into grid structure, and this filler module prolongs flow path along vertically corrugated to being designed to.
Described filler module is done support by bottom filler module, need not to be provided with separately bracing frame, the convenient installation.
Described filler module can be combined or single injection-molded by waved plate and union lever, at different concns waste water, select different lengths union lever or waved plate spacing for use, can change filler module gap, preventing in the sewage that big particle diameter material is sized is trapped in bed of packings, sewage relies on the biomembranous biochemical action that the filler top layer adheres to and degrades in the drippage process, the microbial film that comes off can pass the grid structure bed of packings smoothly, fundamentally prevented the bed of packings obstruction, avoid back flushing, simplified sewage disposal operation process.
Described biology drips bed and can design different filler apertures and fill out the water bed height according to flooded condition, owing to need not to be provided with separately bracing frame, only needs the filler module is directly piled up, and can realize biological the building of bed of dripping.Biological dripping between the bed fillers module group controlled appropriate gap, can satisfy the needs of filler top layer microorganism to oxygen by natural oxygen supply.
Compared with prior art, the present invention has the following advantages:
(1) complete modularization from as support, need not support frame or pond body with the filler module, and is simple in structure, and it is convenient to install, and construction investment is economized;
(2) choose suitable filler module aperture, can prevent in the sewage obstruction of the packing layer that the big particle diameter material and the microbial film that comes off cause, avoided back flushing, simplify sewage disposal operation process;
(3) biological dripping between the bed fillers module group controlled appropriate gap, can satisfy the needs of filler top layer microorganism to oxygen by natural oxygen supply, reduces the sewage disposal energy consumption;
(4) optimize the corrugated plate packing surface tissue, make the microbial film of apposition growth have certain thickness, the outer dissolved oxygen concentration of microbial film is high and inboard dissolved oxygen concentration is low, and dissolved oxygen concentration gradient difference has just been created condition for nitrification and denitrification takes place simultaneously.Simultaneously, along the biological bed water (flow) direction of dripping, the distribution difference of dissolved oxygen also for nitrification and denitrification provides condition, has realized simultaneous denitrification.
Can be according to influent quality water yield feature, certain altitude certain volume filler module is handled rank as one, each is handled rank suction culvert, water distribution system and outlet system is set respectively, according to the treatment process requirement, a plurality of processing ranks are passed through series, parallel and mixed running pattern, thereby reach effective processing the sewage of different Pollutant levels;
(5) microorganism exists with the immobilized biomembrane form in the biology bed, and the operational process sludge yield is few, and local anoxic mud is from digestion and metazoan predation, and whole technology excess sludge production is 1/4th of a conventional activated sludge process.
