Abstract
The invention discloses a landscape water circulation purifying treatment technology. The technology sequentially comprises the following steps: an elevator pump arranged at the tail end of a landscape water pumps water to a water purifying facility, and the water is purified; the elevated water enters a bio-contact nitration pool, aerobic bacteria are used in a bio-contact oxidation pool to degrade ammonia nitrogen and COD in the water, and outlet water enters a coagulative precipitation tank; a flocculating agent is added to the coagulative precipitation tank to remove TP; precipitated outlet water enters a sand filtering process, and suspensions and colloid substances in the water are removed as possible to reduce the pollutant index of outlet water; and the outlet water is finally disinfected by chlorine dioxide to kill pathogens and other microbes in the water, and treated outlet water enters the landscape water. The landscape water circulation purifying treatment technology has the substantial characteristics of standard reaching water quality, low comprehensive investment and operating cost, simple management, and realization of starting or stopping at any time according to practical needs.
Description
Technical field
The present invention relates to a kind of landscape water circulation purification treatment process.
Background technology
Along with the fast development of economy, the requirement of town dweller to periphery life and living environment improves day by day, and the domestic construction to public welfare park is more and more paid attention to, and the quantity in park is explosive growth, and inland lake, park Water quality also more and more receives publicity.
Without the park at external water source, its water pollution main source is the early-stage rainwater of rainfall in region, resident washes clothes waste water and the organic humic of animals and plants etc.The pollutent that above reason produces will greatly destroy lake water water quality, the especially remittance of nitrogen phosphoric after importing lake, and the mobility of water body is poor in addition, will increase the possibility of lake water outburst blue-green algae.
Inland lake, park is polluted and is belonged to micro-pollution, pollute without ripe effective treatment measures for inland lake, park at present, main methods has natural sedimentation to purify and plantation waterplant strengthening reparation two kinds of methods, because two kinds of method manual interventions when day-to-day operation are less, its role is less, impact resistance is poor, and the Water quality of current domestic most inland lake causes anxiety.
In many parks, Lake Water is administered in puzzlement factor, suitable Technology is not had to be primary factor the most, as inadequate to the attention degree of Lake Water Pollution in park and improvement in part park initial investment process of construction, the internal Lake Water daily administration of part park is safeguarded not in place, does not have suitable inland lake water quality purification process etc. to be all the principal elements perplexing the water quality process of inland lake, park.
Seek suitable inland lake, park water quality treatment process technology, become the preposition property important topic of construction of park.
Summary of the invention
The object of the invention is the weak point in order to overcome above-mentioned background technology, providing a kind of water quality of landscape water circularly purifying treatment process, this technique adopts catalytic oxidation+coagulating sedimentation+sand filtration+sterilization Physiochemical and biochemical Combination of Methods, and technique is made up of following steps:
(1) water body is evacuated in water purification facilities and carries out purification of water quality process by the lift pump being placed in landscape water body end.
(2) first promoting water enters in biological nitrification tank, and in biological contact oxidation pond, utilize the metabolism of aerobic bacteria, degrade to the ammonia nitrogen in water body and COD, water outlet enters coagulative precipitation tank.
(3) in coagulative precipitation tank, add flocculation agent, remove TP to greatest extent by the mode of chemical dephosphorization.
(4) precipitate water outlet and enter sand filtration operation, remove the suspended substance in water and colloidalmaterial as far as possible, reduce the pollutent index of water outlet.
(5) water outlet is finally by disinfection by chlorine dioxide, and kill the microorganisms such as the pathogenic agent in water body, the water outlet after process enters in landscape water body.
Landscape water circulation purification treatment process has following outstanding feature:
1, adopt this art breading landscape water physical efficiency to stablize to reach the surface water three class water body standard that landscape water body is strict with.
2, the comprehensive method of investment and running cost relative moderate.
For general landscape water body, adopt the cost of investment of this technique can control at 2000 yuan/ton of water, running cost is greatly about about 0.3 yuan/ton of water.
3, the management of this programme operation is simple, can according to actual needs with opening with stopping.
Accompanying drawing explanation
Fig. 1 is a kind of water quality of landscape water circulating disposal process of the present invention schema.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the present embodiment provides a kind of water quality of landscape water circularly purifying treatment process, comprises the following steps successively:
(1) water body is evacuated in water purification facilities and carries out purification of water quality process by the lift pump being placed in landscape water body end.
(2) first promoting water enters in biological nitrification tank, and in biological contact oxidation pond, utilize the metabolism of aerobic bacteria, degrade to the ammonia nitrogen in water body and COD, water outlet enters coagulative precipitation tank.
(3) in coagulative precipitation tank, add flocculation agent, remove TP to greatest extent by the mode of chemical dephosphorization.
(4) precipitate water outlet and enter sand filtration operation, remove the suspended substance in water and colloidalmaterial as far as possible, reduce the pollutent index of water outlet.
(5) water outlet is finally by disinfection by chlorine dioxide, and kill the microorganisms such as the pathogenic agent in water body, the water outlet after process enters in landscape water body.
Implement the embodiment of the present invention, there is following beneficial effect: landscape water circulation purification treatment process has following outstanding feature: 1, adopt this art breading landscape water physical efficiency to stablize to reach the surface water three class water body standard that landscape water body is strict with.2, the comprehensive method of investment and running cost relative moderate.For general landscape water body, adopt the cost of investment of this technique can control at 2000 yuan/ton of water, running cost is greatly about about 0.3 yuan/ton of water.3, the management of this programme operation is simple, can according to actual needs with opening with stopping.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
