Description
Technical field
The invention belongs to the process fields of sewage, and in particular to a kind of water process algae case, water treatment system and water process side
Method.
Background technique
With industrial progress and social development, water pollution problems is on the rise.The major pollutants of common sewage be COD,
Ammonia nitrogen, nitrate nitrogen and phosphate, these pollutants can promote microorganism to grow, and oxygen depleted causes water body smelly, and fishes and shrimps are dead
It dies.
Traditional biological sewage treatment method such as activated sludge process in contaminant water organic matter, suspended matter removal effect compared with
It is good, but energy consumption is high for treatment process, and total phosphorus, total nitrogen treatment effect are unstable；A large amount of sludge can be supervened in treatment process, brought
Treatment of Sludge and the high problem of cost of disposal；This external equipment is more, management difficulty is larger and the shortcoming of the treatment process.
Due to the wastes such as output a large amount of residual baits, fish faeces in aquaculture pond in aquaculture process, often make water nutrition
Content increases and becomes eutrophic water, and the presence of eutrophic water causes dissolved oxygen to decline, and seriously affects the existence of fish.Currently,
Well known pond culture is pond water quality to be adjusted by carrying out discharge water with outer river, however this method is easy to bring into from Wai He
Pathogen causes the generation of disease.
Currently, high to the generally existing processing cost of the processing of environment water sewage and breeding water body, poor processing effect ask
Topic.
Summary of the invention
The purpose of the present invention is to provide a kind of water treatment systems, to solve the existing processing of existing sewage water treatment method
The problem of at high cost, poor processing effect.Present invention simultaneously provides a kind of method for treating water and water process algae casees.
To achieve the above object, technical solution used by water treatment system of the invention is:
A kind of water treatment system, including the system body for containing water body to be clean and for swimming in water body to be clean
The water process algae case on surface；The water process algae case includes cabinet, has the inner cavity for containing filamentous algae in cabinet, on cabinet
Equipped with the communicating passage for being connected to external water body and the inner cavity to be clean.
Water treatment system provided by the invention absorbs the nutriments such as a large amount of carbon sources, N and P using filamentous algae from water body,
Dissolved oxygen is provided for water body, keeps the ecological functions of water body；Cabinet provides stable space environment for filamentous algae, can strengthen algae and week
The adaptability of water body is enclosed, guarantees the efficient performance of algae bio purification function；Water body and outer may be implemented in cabinet in communicating passage
Portion's water body exchanges, to achieve the purpose that outside body of water Ecological Disposal, the water treatment system structure is simple, is processed into sewage
This is low, effect is good.
Cabinet is equipped with the adjusting door for controlling communicating passage opening and closing degree.Communicating passage includes that the water of body side is handed over
Change the permeable net of hole and/or the bottom of box.By adjusting the water exchange capacity between the setting adjustable case body of door and outside body of water,
Achieve the purpose that control water body characteristic.Can grow nonparasitically upon another plant single-cell algae substance in filamentous algae incubation, using permeable web form
Cabinet, unicellular alga can move Xiang Shuiti from permeable net, realize unicellular alga culture or provide high-quality bait for aquatic fish
The purpose of material.
The cabinet includes cylindrical sidewall, and the lower concave bottom for the sediment precipitating in cabinets cavity is equipped with below cylindrical sidewall
Wall, or/and system body bottom is equipped with the collecting bin for the sediment precipitating in water body to be clean.Preferably, lower concave bottom

Collect the main body sewage pipe of the sediment discharge in storehouse.It is further preferred that water treatment system further include with cabinet sewage pipe and/or
Main body sewage pipe outlet be linked in sequence settling separation device, sand filtering device, sand filtering device have for water body to be clean
The treated water outlet of connection.
The cylindrical sidewall is square tube shape, and it is highly 20~40cm that side length, which is 40~180cm,.It is further preferred that square tube
The side length of shape side wall is 50~100cm, is highly 25~35cm.Square tube shape side wall is surrounded by four pieces of sidewall panelings, the face of intercommunicating pore
Product is the 0.01%~3% of side wall plate suqare.The cabinet of above-mentioned specification is selected, production is simple, and cabinet size is also suitable in cabinet
The normal growth of filamentous algae.
By the setting of cabinet sewage pipe, main body sewage pipe, the sediment collected in cabinet, collecting bin can be arranged in time
Out, sediment is generally the mixture of water and thallus flocculate, microalgae, after sedimentation separation, sand filtration processing, can further mitigate
Pollution to water body.
It is additionally provided in cabinet for providing the light source of illumination in the case where night or not good enough illumination for filamentous algae.On daytime
The photosynthesis that filamentous algae is played by natural light, it is molten to increase night water body by adding light source to strengthen photosynthesis outside at night
Oxygen content is solved, to be beneficial to fish and water body environment.
The light source is LED lamp bead.The power of light source is 2W~100W；Preferably, the power of light source is 3W~10W.It can
According to the distribution mode of light source and the power of quantity flexible setting light source.Additional light source can avoid algae in night oxygen consumption, improve
Night oxygen content of water.
Algae used belongs to Chlorophyta, Chlorophyceae, Cladophorales, Cladophoraceae, root branch algae in water treatment system of the present invention
Category or its close relative float on the water surface its main feature is that spontaneously forming bacterium bed after producing gas in water.
The removal water body that filamentous algae can be convenient effectively and can be removed at low cost and cause the organic of water eutrophication
The nutriments such as object, nitrogen, phosphorus.Root branch algae may be selected in filamentous algae.Root branch algae all has sizable biomass throughout the year, influences
Its factor grown includes the environmental factors such as salinity, temperature, nutrition；The optimum growh salinity and temperature of root branch algae are respectively 20 ‰
With 25 DEG C, as inorganic carbon source NaHCO3When concentration is 2~4mg/L, root branch algae photosynthetic rate with higher；And it adds certain dense
The nitrogen source of degree can effectively promote 2-3 times of its photosynthesis rate in water body again.Root branch algae can not only be using carbon dioxide as carbon
Source, while also can also can promote some microalgae biological growths using bicarbonate radical in water body.It is a large amount of to develop the raw matter money of root branch algae
Source can also reduce environment percent of greenhouse gases content except that can improve water quality.
Technical solution used by method for treating water of the invention is:
A kind of method for treating water, this method are floating setting water process algae case, the water process algae on water body to be clean
