Embodiment example 1

[0078] The water sample was taken from a fish pond, 4L, yellow-green, containing many blue algae, green algae, humus and mud colloids, smelly, turbid liquid, and low visibility. The test value of the PH test paper is 7, and there are algae substances on the test paper.

[0079] Temperature during the experiment: 29℃~30℃

[0080] formula:

[0081] Pollutant treatment agent: slaked lime (Ca(OH) 2 ) 1.1g

[0082] In addition to hard neutralizer: sodium bicarbonate (NaHCO 3 ) 0.3g

[0083] Flocculant: polyaluminum chloride ([Al 2 (OH) n Cl 6-n ] m ) 0.3g

Embodiment example 2

[0085] The water sample is taken from the park landscape lake, the water sample is 5L, it is a light yellow-green turbid liquid, which contains many blue algae, green algae, humus, mud and dust. The test value of the PH test paper is 6, which has a fishy smell.

[0086] Temperature during the experiment: 25℃

[0087] formula:

[0088] Pollutant treatment agent: slaked lime (Ca(OH) 2 ) 1.0g

[0089] In addition to hard neutralizer: sodium bicarbonate (NaHCO 3 ) 0.3g

[0090] Flocculant: Ferric chloride (FeCl 3 ) 0.3g

Embodiment example 3

[0092] Separate a 6m×2m×1.8m water body, about 21.6m, in a heavily polluted small river 3 . The water body is polluted by agricultural sewage, the color is yellow-green, the turbid liquid, the visibility is less than 20cm, the blue algae and green algae are over-proliferated in the water body, and there are many humus and mud dust particles from the rot of rice straw, PH=6.

[0093] Temperature during the experiment: 30℃~33℃

[0094] formula:

[0095] Pollutant treatment agent: slaked lime (Ca(OH) 2 ) 4.8Kg

[0096] In addition to hard neutralizer: sodium bicarbonate (NaHCO 3 ) 0.44Kg

[0097] Flocculant: polyaluminum chloride ([Al 2 (OH) n Cl 6-n ] m ) 0.93Kg

[0098] After the above treatments, it can effectively remove the pollution of algae, phosphorus, nitrogen, heavy metals, etc., effectively reduce the odor of the water body, clarify the water body, and remove the precipitated pollutants with simple operation and low-cost, and use the removed calcium-rich, Nutrient-rich pol...

Abstract

The invention discloses a disposing method of eutrophication water and tank to separate the disposed eutrophication water, which comprises the following steps: putting pollution disposer with Ca(OH)2 or CaO in the disposed eutrophication water; adjusting pH value of water to object pH value through placing hardening-removing neutral agent in the water; adding flocculant to sediment suspension and colloid polymer. The tank contains groove with three rectangle or square jacconettes or baffle boards connecting tightly, wherein two ends of groove connect jacconette or baffle board and separating net as door switched bulk.

Description

Technical field [0001] The invention relates to sewage treatment technology, in particular to a treatment method of eutrophic water. Background technique [0002] Eutrophication of water bodies is the result of abnormal reproduction of autotrophic organisms (mainly phytoplankton) in water bodies rich in nutrients such as nitrogen, phosphorus and organic matter. The eutrophication of water bodies caused by nitrogen and phosphorus pollution is a worldwide environmental problem. At present, about 75% of the waters of lakes in my country are significantly polluted, mainly due to severe eutrophication. Relying on the self-purification and ecological adjustment capabilities of heavily polluted water bodies to restore water quality is very difficult. Signs and hazards of eutrophication include scum and toxins from algae blooms, massive infestation of certain aquatic plants, increased incidence of water-related diseases, decreased water transparency, malodorous water, depletion of dissol...
