Embodiment 1

[0024] In this example, the sewage used is a sewage sample obtained from a local river ditch, the amount of which is 1000 kg, the copper content is 0.74 mg / L, the lead content is 0.12 mg / L, and the pH is 4.7, which belongs to heavy metal pollution body of water. At the same time, it was found that the zinc content was 0.037mg / L (that is to say, the zinc content was very low). The sewage was collected in advance using a 40-mesh sieve to obtain a water body that was basically free of sediment. Moreover, the phosphorus content in the sewage is 0.42mg / m3, and the nitrogen content is 0.71mg / m3, which belongs to the sewage with severe eutrophication.

[0025] This 100 kg of sewage is introduced into the pre-set cement pool, followed by the following steps:

[0026] (1) Add 20 grams of fresh Chlorella pyrenoidosa and 60 grams of fresh Spinospinosa green algae to 1000 kilograms of water, and adjust the content of zinc salt so that the content of zinc salt in the water is 0.35 mg / L c...

Embodiment 2

[0030] In the present embodiment, the sewage used is the same as in Example 1, followed by the following steps:

[0031] (1) Add 10 grams of fresh Chlorella pyrenoidosa and 100 grams of fresh Spinospinosa green algae to 1000 kilograms of water, and adjust the content of zinc salt so that the content of zinc salt in the water is 0.5 mg / L calculated as zinc element;

[0032] (2) Use quicklime to adjust the pH value of the water body obtained in step 1 to 6.5;

[0033] (3) The water body obtained in step 2 was allowed to stand naturally under natural light for 2 days, and the algae in the water were fished out.

Embodiment 3

[0035] In the present embodiment, the sewage used is the same as in Example 1, followed by the following steps:

[0036] (1) Add 100 grams of fresh Chlorella pyrenoidosa and 10 grams of fresh Spinospinosa green algae to 1,000 kilograms of water, and adjust the content of zinc salt so that the content of zinc salt in the water is 0.25 mg / L calculated as zinc element;

[0037] (2) Use quicklime to adjust the pH value of the water body obtained in step 1 to 6.5;

[0038] (3) The water body obtained in step 2 was allowed to stand naturally under natural light for 2 days, and the algae in the water were fished out.

Abstract

The invention discloses a composite algae formulation capable of rapidly removing heavy metals in water and a method for rapidly removing the heavy metals through the composite algae formulation. Thecomposite algae formulation comprises the following raw materials in parts by weight: 10-100 parts of fresh protein nuclear chlorella pyrenoidosa, 10-100 parts of fresh spirogyra green alga, zinc saltand a pH regulator. The composite algae formulation and the method can achieve high-efficiency adsorption on copper salt and lead salt by the combination of the fresh protein nuclear chlorella pyrenoidosa and the fresh spirogyra green alga; and when the adsorption on the lead salt is relatively thorough when the zinc salt is added into the composite algae formulation. The composite algae formulation and the method can be widely applied in wastewater treatment process, and have the wide application prospect.

Description

technical field [0001] The invention relates to the treatment of sewage, in particular to a compound algae preparation for rapidly removing heavy metals in water and a method thereof. Background technique [0002] The amount of heavy metals discharged by humans into the environment is increasing day by day, which not only seriously pollutes water resources, but also brings great harm to human health. At present, physical, chemical and biological methods are generally used for the treatment of heavy metal polluted water bodies, such as precipitation method, chelating resin method, polymer capture method, natural zeolite adsorption method and ion exchange method, etc. The purification rate of the above methods is very high, but the technical process is mostly very long, the operation is cumbersome, and the treatment cost is expensive. Therefore, people have been trying to find a more environmentally friendly method. [0003] Algae has a strong ability to adsorb and enrich he...
