Description
Technical field
The present invention relates to technical field of environmental management, and in particular to a kind of shallow lake solar energy different makings aeration control round the clock
Algae device.
Background technique
As water quality is wanted in the expansion of China's city size, improvement of living standard and social economy's high speed development, city
Ask higher and higher, the demand to water is increasing, and the requirement to ecological environment is also gradually promoted.However, in recent years, with work
The rapid development of agriculture scale, pollutant emission was far super former, and China is most of once as the lake and reservoir eutrophy of source water
Change more serious.Currently, the mean depths such as China's main inland lake such as Taihu Lake, Chaohu, Dian Chi, East Lake only have 1.8-3.0m or so
Shallow lake majority eutrophication is serious, cause alga eruption to take place frequently, water environment is destroyed serious, has been unable to satisfy municipal water
The requirement of source water, therefore gradually cause water source judgment.Meanwhile urban inner small area shallow lake has due to receiving largely to be rich in
The sanitary sewage of machine object and becoming a mandarin for initial rainwater also generate serious pollution, cause algal bloom, if not being controlled,
Surrounding resident life will be seriously endangered, will be brought a negative impact to ecological environment.
Algae largely breeds in shallow-layer lake, brings a series of environmental problems and safe drinking water problem.Algae is suspended in water more
Form wawter bloom in body, and certain cyanobacterias be it is toxic, is decomposed after a large amount of algae are dead by heterotroph in water, generation stench is into one
Severe exacerbation water quality is destroyed ecoscape by step release vivotoxin.In the lake as urban water sources, the taste of algae
It is raw to directly affect tap water production, contain the poison such as tetrachloro-ethylene, dimethyl disulphide in the secretion and catabolite of algae
Property substance, people, animal poisoning can be caused, musty, the fishy smell generated also makes drinking water be difficult to receive on sense organ, long-term low
The intake of concentration algae toxin can be done harm to huamn body.
Raw water high for planktonic algae content at present, water treatment plant can only increase water purification backman during original sub-block
Skill.Usual processing method has following 4 kinds:
1. adding the algicides such as copper sulphate except algae in storage pond；
2. enhanced coagulation and filtering technique；
3. electrocoagulation-flotation and air bearing flotation remove algae；
4. flocculation aid permanganate (PPC) composite drug is added to remove algae.
The above various methods but will be also brought a negative impact simultaneously using reducing in water concentration of algae as final purpose, i.e.,
The destruction of harmful frustule can make the algae toxin in cell discharge into water body, to form the secondary pollution to water quality, simultaneously
A large amount of uses except algae medicament can be such that water treatment plant's operating cost increases significantly.
Therefore, to reduce harmful concentration of algae in water treatment plant's water inlet, control shallow lake alga eruption just must be from source
The eutrophic extent of upper control water body inhibits the growth and breeding of algae in source water.And existing measure both at home and abroad is main at present
Have:
1. surface layer shading method；
2. biological control act；
3. pump up water aeration；
4. bottom storehouse sluicing method.
Above a few class methods can play good effect in terms of controlling algal grown, but these methods all can be by certainly
The limitation of body technology and there are certain disadvantages:
1. surface layer shading method works well, but since shading-area limits, control algae ability is limited, water body algae other than shading region
Class is unaffected, while will affect other in water body beneficial to the growth of aquatile.
2. biological control act is generally the consumer or competitor for cultivating algae, such as fresh-water fishes, planktonic organism, emergent aquactic plant
Etc. algae bio amount is controlled, the method clean and environmental protection is energy saving.However since algae reproduction speed is exceedingly fast, competitive advantage
It is too strong, lead to eutrophic water body Mesichthyes hypoxia death, is extremely difficult to desired effect.
3. the aeration that pumps up water is to can achieve increase Dissolved Oxygen in Water by installing different types of aerator in bottom storehouse
Inhibit the effect of Nutrient release and disturbance mixed water body in bed mud.But this kind of method is suitable for deep water type lake and reservoir, and
Generally existing energy consumption excessive the technical issues of need to being regularly maintained with equipment, cause control algae cost to be greatly improved in use process, difficult
To promote on a large scale.
4. bottom storehouse sluicing method can effectively slough bottom nutriment, algae source of nutrition is cut off, achievees the purpose that algal control, but
The method lake and reservoir storage capacity loss lesser for water-holding quantity is larger, and bottom storehouse sluice operation difficulty is big, and risk is higher.
