Embodiment:
Below the present invention is specifically described:
The present invention adopts and cuts down landscape water body holophytic nutrition material by the mode of enrichment, transfer algae with the following method, landscape water body is tending towards and reaches oligotrophication's state or reach the requirement of national Environmental Quality Standard of Surface Water GB3838-2002.
In water cycle process, first, landscape water body is introduced lift pump, dosing coagulant, landscape water body, after lift pump supercharging coagulation, enters coarse filter.In coarse filter, remove the macrobead foreign material of more than 1mm in landscape water body.
Landscape water is after coarse filter purification, and enter the former water water inlet system of fine filting machine, then enter fine filting machine water distribution system, former water, after fine filting machine water distribution system is evenly uniformly distributed, enters filtrate district by support system.In filtrate district, algae, turbidity material tiny flocculation, absorption, precipitation and retained by filtrate on every filtrate in landscape water body, the algae in water, turbidity material are removed.Landscape water body is through the thickness≤2500mm in speed≤45m/h, the 600mm≤filtrate district of filtrate.The clearance of algae reaches more than 99%, and turbidity material clearance reaches more than 98%.
Water after the purification of filtrate district enters purification pool, then collects through rising pipe, and by purifying waste water, rising pipe flows out.After purifying waste water and adding microbial preparation and biological algicide in rising pipe, inflow landscape water body of purifying waste water.
In landscape water body, but biological algicide kills mud tongue, liver moss, unarmored dinoflagellate, blue-green algae, silk algae etc. in landscape water body; Organic waste, as residual bait, ight soil, organic debris, dead algae etc., are cleared up into small organic molecule and the inorganics of algal grown breeding, for the algae-bacteria symbiotic system in landscape water body provides matter and energy by the organic waste in biotechnological formulation decomposition water body; Simultaneously, because the landscape water body after purification has higher visibility meter, the illuminance of higher sunlight significantly promotes the photosynthesis of algae, impels algae in landscape water body with growth rate and breeding faster, the holophytic nutrition material in fast enriching landscape water body.
Through the repeatedly circulation of landscape water body purification system, holophytic nutrition material in landscape water body is by algae enrichment and transfer, its concentration is more and more lower, and water quality is tending towards gradually and reaches oligotrophication's state or reach the requirement of national Environmental Quality Standard of Surface Water GB3838-2002.
In actually operating, when water quality of landscape water reaches the water quality demand of user, purification system can quit work.
When fine filting machine filters, the algae in landscape water body and turbidity material are retained down by filtrate district filter material layer gradually, and after repeatedly water cycle, filter material layer is more and more dirtier, and now fine filting machine needs back flushing.
During fine filting machine back flushing, open the valve on blow-off pipe, close the valve on rising pipe, fine filting machine enters back flushing state.In fine filting machine backwash process, fine filting machine still keeps flooding quantity when filtering.First, booster air pump, pressurized gas is inputted by inlet system, pressurized gas is after the even gas distribution of gas distribution pipe of water distribution system, filtrate district is entered through support system, filtrate in filtrate district starts to expand and back flushing, and the sewage of back flushing and pressurized gas enter rising pipe and sewage backwash pipe through sewage backwash district, then enter drainage.When fine filting machine air-water backwashing is after 4-15 minute, stop air pump air feed, air-water backwashing terminates; Now enter water rinse state, after 4-15 minute, after the sewage in filtrate drains substantially, back flushing terminates.Now, open rising pipe valve of purifying waste water, close sewage backwash tube valve, fine filting machine formally enters filtration condition.
See Fig. 1, be system composition of the present invention and method flow diagram.
A kind of city appearance water body integrated conduct method, it comprises the following steps:
(1), by landscape water body introduce lift pump, with coagulating agent mixing in lift pump, carry out reaction flocculation; Described coagulating agent is aluminium salt or molysite; Aluminium salt is Tai-Ace S 150, polymerize aluminum chloride, and its concentration is 1.0-10ppm; Molysite is ferrous sulfate, ferric sulfate or iron trichloride;
