Abstract
The utility model provides a water treatment device of carbon fiber ecological grass rivers and lakes and belongs to the field of sewage treatment. A water inlet pool (1) of the water treatment device is connected with an anaerobic pool (3) through a water inlet pump (2), the anaerobic pool (3) is connected with a mixed liquid backflow pipe, carbon fiber ecological grass is arranged in the anaerobic pool (3) from top to bottom, the anaerobic pool (3) is connected with an anaerobic pool (4) through a flashboard at the bottom, carbon fiber ecological grass is arranged in the anaerobic pool (4) from top to bottom, the anaerobic pool (4) is connected with an air compressor (5) and an air flow meter (6), the anaerobic pool (4) is formed by connecting more than two anaerobic pools in series, the anaerobic pool at the tail end is connected with a mixed liquid backflow pipe, the mixed liquid backflow pipe is connected with the mixed liquid backflow pipe of the anaerobic pool (3) through a mixed liquid backflow pump (8), and the anaerobic pool (4) is connected with a water outlet pool (7). The carbon fiber ecological grass is used as microbial carriers, chemical oxygen demand (COD) and content of pollutants of nitrogen are reduced remarkably, and the water treatment device of carbon fiber ecological grass rivers and lakes is remarkable in effects of water inlet impact load fighting and sludge reduction and has the advantages of being small in occupied area and good in quality of treated water.
Description
Technical field
The utility model relates to the ecological careless river of a kind of thomel lake water treatment unit, belongs to sewage treatment area.
Background technology
In recent years, river Lake Water Body eutrophication incident frequently takes place in China, and nitrogen, phosphorus are the principal elements of eutrophication, and country has put into effect more strict surface water standard for this reason.Up-to-date " national water environment quality standard GB3838-2002 " regulation, IV class water body emission standard is COD
Cr≤30mg/L; NH
3-N≤1.5mg/L.Because it is serious further that the epibenthic sewage discharge in river is polluted surface water body, keep river and lake water quality pressure up to standard also increasing.Therefore, through arranging that in the prior biological treatment unit the ecological grass of thomel (carbon fiber bundle) as microbe carrier, reaches the purpose that purifies water.This device has anti-shock loading, improves COD and the advantages such as denitrification effect, minimizing sludge yield removed.
At present, ecological grass of thomel and the scientific research of biological treatment device bonded in China seldom do not have enough scientific and technological achievement propping works to use yet, and the underbraced of scientific and technological achievement influences applying of the ecological grass of thomel.Because the present stage pollution problem of China river Lake Water Body is more and more serious; Press for and carry out the environmental protection of this type of the ecological grass of thomel, energy-conservation, waste disposal plant and the exploitation of related process Study on Technology efficiently, for water pollution control field provides practical, efficient, power-saving technology.
The utility model content
The utility model provides the ecological careless river of a kind of thomel lake water treatment unit, is through arranging that in bio-reactor the ecological grass of thomel improves the technology of river lake water biochemical treatment effect.
The ecological careless river of thomel lake water treatment unit comprises: suction sump 1, intake pump 2, anoxic pond 3, Aerobic Pond 4: connect at least 2 ponds, air compressor machine 5, air flowmeter 6, outlet sump 7 and mixed-liquor return pump 8.It is characterized in that: suction sump 1 links to each other with anoxic pond 3 through intake pump 2.Anoxic pond 3 connects the mixed-liquor return pipe, and inside is arranged the ecological grass of thomel from top to bottom, and is connected with Aerobic Pond 4 through the bottom flashboard.Aerobic Pond 4 inside are arranged the ecological grass of thomel from top to bottom, are connected with air flowmeter 6 with air compressor machine 5; 2 above Aerobic Ponds of Aerobic Pond 4 series connection, terminal Aerobic Pond is connected with the mixed-liquor return pipe, and the mixed-liquor return pipe links to each other with the mixed-liquor return pipe of anoxic pond 3 through mixed-liquor return pump 8.Aerobic Pond 4 is connected with outlet sump 7.
Through the river lake water that this method was handled, the concentration of its suspended substance, biochemical oxygen demand, nitrogen is all lower, and the relative conventional activated sludge method of required floor space is less.This device can reduce the volume of bio-reactor greatly, significantly reduces and removes COD and the required floor space of denitrogenation.Suit the ecological grass of thomel is used for the upgrading of existing sewage work, and, can greatly reduce the capital construction cost owing to sludge treatment equipment need be set.
Description of drawings
Fig. 1 is the ecological careless river of a utility model thomel lake water treatment unit schematic diagram.
Among the figure: 1 suction sump, 2 intake pumps, 3 anoxic pond, 4 Aerobic Ponds, 5 air compressor machines, 6 air flowmeter, 7 outlet sumies and 8 mixed-liquor return pumps.
Embodiment
The device of the utility model has had detailed description in the utility model content, and this place repeats no more.
The treatment unit mode of operation: contaminated river lake water at first gets into suction sump 1; Through intake pump 2 with sewage transport to anoxic pond 3; Denitrifying bacteria utilizes organism and the nitrate salt in the backflow mixed liquor in the water to carry out denitrification in the anoxic pond; Carbon elimination denitrogenation simultaneously, anoxic pond 3 links to each other with Aerobic Pond 4 through the bottom flashboard, and the sewage flow by gravity gets into Aerobic Pond.When sewage got into Aerobic Pond 4, air compressor machine 5 produced oxygen through air flowmeter 6 controls, makes the autotrophic type nitrobacteria under the competent condition of dissolved oxygen, ammonia nitrogen is converted into nitrate nitrogen, realizes the purpose of denitrogenation; The microbial consumption that possesses the organic matter degradation ability is simultaneously fallen carbon source in the sewage and is reached and remove organic purpose.Aerobic Pond 4 is connected with anoxic pond 3 through mixed-liquor return pump 8, and with a part of mixed-liquor return to anoxic pond 3, Aerobic Pond 4 links to each other with outlet sump 7 through rising pipe.
The logical favour river in Beijing is adopted in water inlet, and water quality is following: COD 40～60mg/L, NH
3-N2～6mg/L.Through this reactor for treatment, water outlet COD content is 4～6mg/L, and clearance is more than 90%; NH
3-N content is less than 0.1mg/L, and clearance is more than 95%.Water outlet COD, ammonia nitrogen all satisfy " national water environment quality standard GB3838-2002 " IV class water body emission standard; The ecological careless river of thomel lake water treatment unit is handled river lake water and can be obtained denitrification effect preferably, and this utility model has been applied to the urban rivers and lakes water treatment.
This device is fit to existing water treatment plant's denitrogenation upgrading and newly-built treatment plant.This treatment unit has the advantages that to save floor space, raising processing power and do not produce excess sludge.
