Description
Technical field
The present invention relates to environmental technology field, particularly relate to the device for purifying water quality of sight waterbody that a kind of submersible type has denitrification functions.
Background technology
Along with the raising day by day of standard of living, the pursuit of people to living environment is also more and more higher, has also occurred increasing landscape water body.These communities, landscape water body park etc. mostly are the closed water body of hand digging, the self-detergent power of water body is natively very weak, owing to being constantly subject to the impact of other natural pollutions such as periphery sanitary sewage and rainy runoff, water quality is unstable, serious generation blue-green algae, water quality blackout is smelly, and mosquitos and flies such as to grow at the phenomenon, has a strong impact on the environment of neighboring area.
The way of current domestic employing has two kinds substantially, one is in pond extracorporeal treatment mode, namely water is extracted outside the body of pond circulates in inflow pond after purification, although which process is relatively good, but construction cost is high, problems such as operational management is loaded down with trivial details to such an extent as to use could not be popularized on a large scale, another is processing mode in the body of pond, such as aeration aerating, biological floating island, waterplant etc. is cultivated around pond, these ways all can not the pollution substance of effective place to go water body, and the plant of cultivation needs periodical reaping, maintenance management is not good at easily producing negative interaction to water body purification.Also some purification facilitys in the body of pond newly developed are had recently, in these ponds, purification facility is due to complex structure, the easy fault of the mechanical means used under water, and the filler purification efficiency used is low, and be easy to saturated, for this is very limited to water body purification effect.According to statistics, the major cause being much in the many lakes of bad V class water quality and landscape water body is at present because total nitrogen index severe overweight, and general purification facility is very low to the nitrogen removal rate of water body, especially almost total nitrogen cannot be removed at the water body of low stain load.
Chinese patent CN102079576 " a kind of surface water protection and the pleuston reactor repaired "; this invention is the vertical tube cylindrical shell swimming in the water surface; continuous for water input reactor as biofilm carrier built with porous material, is flowed through biofilm surface and makes it to be purified by submersible pump by pipe cylindrical shell.The form of fountain is designed at rising pipe.The power of this invention is submersible pump, and owing to forming fountain, the ability that not only consumes is large, and continuous print draws water in a large number, easily water foreign pasture and water etc. because suction function causes the blocking of submersible pump.In addition because swimming in the water surface, have impact on water landscape effect.
Chinese utility model patent (application number 200820041174.2) " surface water comprehensive water treatment device ", this invention is provided with floating drum, inner and outer tubes, the suitable for reading same of inner and outer tubes is connected with a rising pipe, interior pipe has filtration biochemical treatment equipment, and polluted water is promoted by impeller and counts inner and outer pipe by aeration, is filtered-biochemical treatment in interior pipe, finally rise to rising pipe, flow out circulation from water diversion disk and return water body.Water body oxygenation in continuous working cycle, filters and biochemical reaction, reaches the object of purification of water quality.But lead to due to inner and outer pipes two and be subject in identical impeller lifting force, and interior pipe is filled with filter packing, sewage easily passes through from the outer tube that resistance ratios is less for this reason, forms short stream, and namely sewage does not fully enter into the interior pipe being filled with biologic packing material and carries out biochemical reaction.
And, the common problem that the research of the biologic packing material of existing water body purification apparatus filling exists: is that the filler of facility is low to contaminant removal efficiency such as COD, BOD of water body, and decontamination effect improving is unstable, and work-ing life is short.Two is the water bodys in low stain concentration range, owing to lacking carbon source, very low to the clearance of total nitrogen.
Summary of the invention
A kind of submersible type is the object of the present invention is to provide to have the device for purifying water quality of sight waterbody of denitrification functions.This refining plant not only can remove the BOD of water body for a long time efficiently, and the pollution substances such as COD, can also remove ammonia nitrogen and the total nitrogen of water body.
