The invention provides a landscape water treatment technology which comprises steps as follows: (1) landscape water in a landscape water body is introduced into a primary filter and large-grained impurities in the landscape water are removed by the primary filter; (2) a flocculating agent is added to the landscape water treated by the primary filter, and the landscape water and the flocculating agent are introduced into a pipeline mixer by a water inlet pump of a floatation machine so as to be fully mixed; (3) the flocculating agent and the landscape water which are fully mixed are added to the floatation machine, the floatation machine fully mixes the flocculating agent and the landscape water which are fully mixed to remove algae in the mixture; (4) the landscape water purified by the floatation machine is added to a fine filter, and small-grained impurities in the landscape water are removed by the fine filter; (5) a microbial preparation and a biological algicide are added to outlet water purified by the fine filter, and then the water enters the landscape water body.
Description
Technical field
The present invention relates to field of environment engineering technology, particularly relate to a kind of landscape water treatment technology.
Background technology
The reason that landscape water is polluted roughly has following several, and one is landscape water itself is a pool of stagnant water, does not have mobility, reoxygenation ability, and the organic ability of bio-oxidation is more weak, therefore water body self-purification ability is poor.Two is extraneous contaminations, entering of the pollutent brought into as rubbish, chip, airborne dust, leaf, rainwater and other waste water, and these materials rot in water, diffusion, dissolve and precipitation, produces or directly brings a large amount of organic-inorganic thing into, water quality is worsened further.Three is that the biology that purifies water in landscape water body is single, does not form corresponding biologic chain, causes the biological growth difficulty having detergent power.Four is endogenous pollutions of landscape water, and many script innoxious substances enter water body and sink in the middle of bed mud, through after a period of time, chemical reaction occurs between these innoxious substances and generates harmful pollution substance, water body is worsened more.
Present landscape water body purification technique is divided into two large class methods according to its feature:
One, closed material internal recycle method, these class methods have chemical method, microbially decontaminate method, ultrasonic purification method, contact oxidation method etc., these class methods utilize chemical agent to suppress algal grown, or suppress algae, supersonic killing suppression algae etc. by microbial decomposition, although these class methods can suppress the Growth and reproduction of algae the short period of time, but As time goes on, the holophytic nutrition materials such as the nitrogen phosphorus in landscape water body all the time in water, the bottom realize inner material circulation, all the time can not to move out water body, thus landscape water body eutrophication gradually.Adopt the general water quality of the landscape water body of these class methods poor, or later stage operational management cost is very high.
Two, open material outer circulation method, these class methods have wetland method, By Bubble-floating Method, filtration method or other integrated conduct method, the feature of these class methods is that the holophytic nutrition substances such as the nitrogen phosphorus in landscape water body move out from water body by various mode, thus landscape water body is tending towards gradually and reaches oligotrophication's state.But due to the difference of technique, the difference of each art breading unit efficiencies, there is greatest differences in the front-end investment cost of various treatment process, operational management cost, operational management difficulty, shipwreck degree, water quality quality.
In addition, because landscape water body water treatment project is the project not having to take in, excessive front-end investment cost, operational management cost bring huge economic pressures to the manager of landscape water body, meanwhile, the environmental quality of city appearance water body surrounding enviroment soil an inch of land is an inch of gold and the climatic characteristic of China's north and south greatest differences also significantly limit the treatment process of landscape water body.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, a kind of landscape water treatment technology method and system are provided, seek a kind of mode by enrichment, transfer algae cut down the technical problem of landscape water body holophytic nutrition material to solve.
The present invention is achieved in that a kind of landscape water treatment technology, comprises the steps: that the landscape water in landscape water body is introduced primary filter by (1), removes oarse-grained foreign material in described landscape water by described initial filtrator; (2) by flocculant concentration in the landscape water through described primary filter process, and described landscape water and flocculation agent are introduced in line mixer, so that described flocculation agent and landscape water are mixed fully by air floatation machine intake pump; (3) will add in air floatation machine through well-mixed described flocculation agent and landscape water, described air floatation machine at the beginning of the mixing will entered point through well-mixed described flocculation agent and landscape water, to remove algae in mixture, bacterium and microorganism; (4) landscape water through air floatation machine purifying treatment is added in fine filting machine, removed the foreign material of described view tiny particle in water by described fine filting machine; (5) by the landscape water through fine filting machine filtration treatment, after adding microbial preparation, biological algicide, landscape water body is entered.
Particularly, in step (1), the filtering accuracy of described primary filter is 0.8-4mm.
Particularly, in step (1), by described air floatation machine intake pump, described landscape water is introduced air floatation machine.
Particularly, in step (3), add the landscape water after flocculation agent and enter process pipe mixing tank respectively and flocculate.
Particularly, in step (4), the filtering accuracy of described fine filting machine is 0.6-0.8mm.
Beneficial effect of the present invention is: landscape water treatment technology provided by the invention, comprises the steps: that the landscape water in landscape water body is introduced primary filter by (1), removes oarse-grained foreign material in described landscape water by described initial filtrator; (2) by flocculant concentration in the landscape water through described primary filter process, and described landscape water and flocculation agent are introduced in line mixer, so that described flocculation agent and landscape water are mixed fully by air floatation machine intake pump; (3) will add in air floatation machine through well-mixed described flocculation agent and landscape water, described air floatation machine at the beginning of the mixing will entered point through well-mixed described flocculation agent and landscape water, to remove algae in mixture, bacterium and microorganism; (4) landscape water through air floatation machine purifying treatment is added in fine filting machine, removed the foreign material of described view tiny particle in water by described fine filting machine; (5) by the landscape water through fine filting machine filtration treatment, after adding microbial preparation, biological algicide, enter landscape water body, can solve and seek a kind of mode by enrichment, transfer algae and cut down the technical problem of landscape water body holophytic nutrition material.
