The utility model has the advantages that relative to prior art:
Suitable for city of the surface water as water source such as the Jiang ﹑ He ﹑ Hu ﹑ pools, after treatment, mud can be done at extensive use of chemical fertilizer Reason, for the fertilizer of plant, sewage subtracts dirty discharge by eliminating filtration treatment.
Brief description of the drawings
Fig. 1 is the structural representation of municipal sewage sludge processing system.
In figure:
Filter the setting pot 4 of the barrier 3 just coagulative precipitation tank of 5 biological treatment tank of shallow lake pond, 6 second pond 7 in 1 sewage pipe road junction 2 The dewatering centrifuge 14 of 8 chemicals dosing plant, 9 filter, 10 11 initial sludge pipeline of outlet pipe, 12 mud concentration basin 13 flows back dirt The excess sludge pipeline of mud pipeline 15
Specific embodiment
The utility model will be further described with reference to the accompanying drawings and examples.
There is wastewater treatment, the tendency of light Treatment of Sludge emphatically in China.Many cities are not using the treatment of sludge as sewage The necessary component of factory, after often sewage treatment plant builds up, sludge treating system is just built after considerable time, causes me State's city sewage and sludge handling rate is very low.But in terms of Treatment of Sludge, China also lacks practical experience and design experiences, especially The integral level of sludge treating system also than relatively low, from terms of the sludge treatment equipment of built sewage treatment plant, operating condition It is not good, it is impossible to after ensureing that longtime running, the device of many factories build up, larger technological transformation to be carried out again, cause human and material resources and The significant wastage of financial resources.
The utility model provides a kind of municipal sewage sludge processing system, and sewage pipe road junction 1 sets one and filters barrier 2, Filtering barrier 2 is oblique, tentatively isolates debris, and the filtering barrier 2 connects setting pot 3 by pipeline, and sewage is by filtering After barrier 2, into setting pot 3, sewage is inevitably mixed into silt particle during migrating, flowing and collecting.Sand in sewage If not advance sedimentation separation removal, can influence the operation of subsequent processing device.Most importantly abrasion pump, blocking is managed Net, interference even destruction biochemical processing process process.Particle diameter is more than 0.2mm during setting pot 3 is mainly used in removal sewage, and density is big In 2.65t/ cubic metres of sand grains, with facilities such as protective conduit, valves from wearing and tearing and blocking.Its operation principle is with gravity point Based on, therefore the water inlet flow velocity of setting pot should be controlled so that heavy inorganic particle sinks, and organic suspension particle can Taken away with current.Setting pot mainly has horizontal-flow grit chamber, aerated grit chamber, rotational flow grit chamber etc..The main of modern designs has rotation Stream setting pot.
The setting pot 3 connects just shallow lake pond 4 by pipeline, and just shallow lake pond 4 is to remove suspension in water removal using precipitation A kind of structures, sedimentation basin is widely used in the treatment of waste water.Its pattern is a lot, and advection can be divided into by pool inner water stream direction Formula, vertical-flow and three kinds of radial-flow.The just shallow lake pond 4 connects biological treatment tank 5 by pipeline, and biological treatment tank 5 is to sewage The place of microbial cleaning is carried out, wherein containing substantial amounts of beneficial microbe, heavy metal ion, the Fu Ying in sewage can be absorbed Support the nuisances such as material so that sewage can become more clean, accelerate sewage purification.The biological treatment tank 5 passes through pipeline Connection second pond 6, second pond 6 is the important component of activated Sludge System, and its effect mainly separates sludge, makes mixing Liquid clarification, concentration and returnedactivatedsludge.Its working effect can directly affect effluent quality and the backflow of activated Sludge System Sludge concentration.The second pond 6 connects coagulative precipitation tank 7 by pipeline, and coagulative precipitation tank 7 is of sedimentation basin in wastewater treatment Kind.Coagulation process be it is most basic in industrial water and sanitary sewage disposal be also particularly important processing procedure, by water Some medicaments (commonly referred to coagulant and flocculation aid) are added, the particle for being difficult to precipitate in water is aggregated with one another and is formed glue Body, then combines to form bigger floccule body with the impurity in water body.Set between the second pond 6 and coagulative precipitation tank 7 and added Medicine device 8, chemicals dosing plant 8 is carried out disinfection by dosing to sewage, and the coagulative precipitation tank 7 connects filter 9, institute by pipeline State the connection outlet pipe 10 of filter 9.
The lower section in the just shallow lake pond 4 sets initial sludge pipeline 11, and beginning sludge pipeline 11 excludes mud, the initial mud The connection slurries filtering barrier 2 of pipeline 11, the filtering barrier 2 connects mud concentration basin 12 by pipeline, in mud concentration basin 12 Flocculant is added, the mud concentration basin 12 connects slurry dewatering centrifuge 13, the slurry dewatering centrifuge by pipeline 13 connection sludge pumps.Sludge pump conveys mud;The lower section of the second pond 6 sets returned sludge pipeline 14, the returned sludge Pipeline 14 connects the bottom of biological treatment tank 5.The lower section of the second pond 6 sets excess sludge pipeline 15, the excess sludge Pipeline 15 connects initial sludge pipeline 11.The setting of above-mentioned pipeline can be with circular treatment.
The purpose of Treatment of Sludge is to make sludge reduction, stabilisation, comprehensive utilization.At all kinds of sewage of domestic city For reason factory, it should constantly improve its sewage sludge handling process.Mud after dewatering centrifuge 13 is dehydrated can carry out aerobic heap Fertilizer, aerobic compost is, using the effect of microorganism, sludge to be converted into the process of humic-like substance, can eliminate sludge stench, compost Sludge stabilizing, innoxious degree are high afterwards, are economical and convenient, the innoxious substitute technology of sludge stabilizing of high-efficiency low energy consumption.
Although the utility model is disclosed as above with preferred embodiment, so it is not limited to the utility model, any Those skilled in the art, not departing from spirit and scope of the present utility model, when a little modification and perfect, therefore this can be made The protection domain of utility model is when by being defined that claims are defined.
