Abstract
The present invention belongs to the field of environment harnessing technology, and is especially method of inhibiting blue green algae growth and treating water pollution comprehensively. The method includes: setting floating fences in polluted water and planting hyacinth inside the fences, controlling the propagation of hyacinth and fishing out excessive hyacinth, planting the fished out hyacinth in newly set floating fences, and anaerobic fermenting the excessive hyacinth to produce marsh gas. The method of the present invention has low cost and high reward.
Description
Technical field:
The invention belongs to the environmental improvement technical field, especially a kind of method of comprehensive treatment of polluted water by inhibiting growth of blue algae.
Background technology:
Because the increase and the process of urbanization of population, the organism that makes people discharge in water system is more and more, and organic increasing derives from sanitary sewage and industrial sewage and cause the nutritive substance of water body such as lifting capacity such as nitrogen, phosphorus to exceed standard.The reason that blue-green algae wreaks havoc appears in basins such as Taihu Lake, Chaohu, Dian Chi and Changchun reservoir, is to pollute the body eutrophication that causes, and the water ecology structure is damaged.Make contaminated water quality obtain fundamental turn for the better, it is clear that water quality is become, the improvement work relationship of pollution of area source is to the recovery of whole basin environmental ecology, methods such as the method for physics that employing is conventional and chemistry, bactericidal purifying technology, microbial technique processing, biological treatment, because of concerning the water intaking hygienic safety of waterhead area in the basin, must be very prudent.
Handle the water that pollutes its water correction can be utilized again, a lot of methods and approach are arranged both at home and abroad, in recent years, bioremediation more and more is subject to people's attention, and the breadth and depth of research has all had considerable progress.Bioremediation also can serve the same role, even also is better than the method for conventional physics and chemistry in some aspects.
Summary of the invention:
Task of the present invention is to provide a kind of method of comprehensive treatment of polluted water by inhibiting growth of blue algae.
The present invention comprises: (1) becomes " Lian Chi " with float type fence circle on contaminated waters, " Lian Chi " is fixed on the water surface breeding Herba Eichhorniae in " Lian Chi "; (2) control Herba Eichhorniae breeding quantity is in time salvaged the Herba Eichhorniae of " superfluous relatively ".
The present invention, described " Lian Chi " can be cast anchor on the dark water surface of stuck-at-.2-1.8 rice.
The present invention can produce biogas through anaerobically fermenting with the Herba Eichhorniae of salvaging, as the new forms of energy raw material.
Sum up after deliberation: Herba Eichhorniae is at nutritive substances such as a large amount of nitrogen of necessary for growth, phosphorus, and under optimum conditions, one hectare of Herba Eichhorniae can sponge nitrogen, the phosphoric of 800 people discharging the same day.Herba Eichhorniae is also to heavy metal ion, for example: mercury, cadmium, thallium, silver, cobalt, strontium, lead etc. are tackled freely, and agricultural chemicals and other artificial-synthetic compounds etc. is had extremely strong accumulation ability.It can reach more than 95% the organic pollutant clearance rate in the petroleum wastewater, but also environment secretes sterilization factors towards periphery, and it can suppress the growth of blue-green algae, also comprises other algae, mushroom.
The present invention, on contaminated waters, the breeding Herba Eichhorniae is in time salvaged the Herba Eichhorniae of " superfluous relatively ", the growth of an amount of Herba Eichhorniae can reach the GB898-1996 emission standard to the purification of water quality, and the less energy consumption that does not need to drop into again energy consumption or input can also the regenerated energy resource.The breeding Herba Eichhorniae is administered blue-green algae and be can be described as a kind of with low cost, save energy, operating cost is low, regeneration is easy, better results simple and feasible method.
Embodiment:
Through experiment, every 4-7m
2Herba Eichhorniae breeding area, can purify 1 ton of contaminated fresh water in 7-10 days.Now with 5m
2Be the unit surface of disposing of sewage, can handle 1 ton of polluted water with per 10 days and calculate.
If: the water that polluted by blue-green algae is about 60,000m
3, external discharging every day flows into about 100 tons of the sewage in this waters, and Herba Eichhorniae breeding area is 75 mu on the water surface, is about 50000m
2, become " Lian Chi " with every 0.5-1.0 mu water surface with float type fence circle, casting anchor is positioned on the dark water surface of 1.2-1.8 rice; Breeding Herba Eichhorniae in " Lian Chi ", then:
y＝x÷((50000÷5÷10)-100)
＝60000÷((50000÷5÷10)-100)
＝60000÷(1000-100)
＝60000÷900
≈ 67 (my god)
In the formula, y: handle sewage fate (my god); X: the sewage number (ton) of expression water body; Can handle whole sewage in 67 days.Water quality treatment reaches the GB898-1996 emission standard in 67 days described basins.If the waters divides the location to handle, the available towboat of these floatation types " Lian Chi " moves to other waters that need handle " operation " to it.
Through experiment, every strain Herba Eichhorniae can be bred next strain in per 5 days, then:
A＝m×2
(n/5)
In the formula: A: the strain number after the expression breeding; M: expression radix; N: expression fate.
If with every mu 0.2 ten thousand strain Herba Eichhorniae is breeding radix (m), then the Herba Eichhorniae of every mu of breeding increases to 12.8 ten thousand strains after 30 days.
Through experimental observation, when the Herba Eichhorniae number of every mu " Lian Chi " was 6-8 ten thousand strains, scrubbing decontamination effect improving the best when the Herba Eichhorniae number in every mu " Lian Chi " surpasses 100,000 strains, because density is too high, can influence the Herba Eichhorniae growth and breeding, and the scrubbing decontamination effect improving descends on the contrary.Therefore, should rationally control Herba Eichhorniae breeding quantity, in time salvage the Herba Eichhorniae of " superfluous relatively ".
According to above calculating, throw when initial and support 0.2 ten thousand strain Herba Eichhorniaes as if every mu " Lian Chi ", can carry out the Herba Eichhorniae of salvaging for the first time " superfluous relatively " after 25-30 days, the quantity of salvaging is about 1/2nd of " Lian Chi " interior Herba Eichhorniae number.Salvage once every 8-10 days summer later on, salvage once every 20-30 days winter, and the quantity of salvaging remains about 1/2nd of " Lian Chi " interior Herba Eichhorniae number.
After the water quality of handling in the basin reaches the GB898-1996 emission standard basically, part floatation type " Lian Chi " can be moved to other waters that need handle " operation " to it with towboat.Retained part " Lian Chi " continues that scrubbing is carried out in the waters and purifies, and the quantity of reservation is decided on the quantity of the sewage of discharging every day.
The present invention, to salvage the Herba Eichhorniae of " superfluous relatively ", can be used for increasing newly " Lian Chi " breeding breeding, also can utilize Guangdong Qitian Chemical Pesticides Co., Ltd to study successfully " method and device that the residual body of comprehensive utilization Herba Eichhorniae is produced biogas " patent of invention technology, produce biogas through anaerobically fermenting, as the new forms of energy raw material.
Therefore, the simple and feasible method that the present invention is a kind of with low cost, save energy, operating cost is low, regeneration is easy, better results is rich in application value.
