Problems solved by technology

However, although many microalgae have a certain ability to adsorb heavy metal ions, the adsorption efficiency of microalgae in the natural environment for heavy metal ions is limited, and many microalgae have poor tolerance to heavy metal ions, which greatly limits the ability of microalgae to absorb heavy metal ions.

Embodiment 1

[0024] A kind of preparation method of the coconut shell activated carbon adsorbent of novel loading chlorella, the steps are as follows:

[0025] (1) Preparation of coconut shell activated carbon

[0026] Wash the coconut shell with deionized water, crush it, sieve it (100 mesh), and dry it in an oven (80° C.). Put the coconut shell powder in a ceramic crucible, wrap it with tin foil and place it in a muffle furnace, carbonize it at 900°C for 3 hours, cool it to room temperature and take it out, and pass the obtained product through a 100-mesh standard sieve to obtain coconut shell activated carbon.

[0027] (2) Cultivation of Chlorella (Chorella)

[0028] Chlorella algae (FACHB-8) was purchased from the freshwater algae bank of the Chinese Academy of Sciences, and the algae were cultivated and transferred by themselves. The specific methods are as follows:

[0029] ① After receiving the algae seeds, shake the algae seeds in the test tube, transfer them directly into a glas...

Abstract

The invention discloses a novel chlorella-loaded coconut shell activated carbon adsorbent as well as a preparation method and application thereof, and belongs to the technical field of biology. The coconut shell activated carbon adsorbent is prepared from coconut shell activated carbon and living chlorella. The preparation method comprises the following steps: (1) preparing the coconut shell activated carbon; (2) preparing living chlorella; and (3) mixing and oscillating the coconut shell activated carbon and living chlorella to obtain the novel chlorella-loaded coconut shell activated carbon adsorbent which achieves the effect of 1 + 1 > 2 on heavy metals in different time periods. According to the present invention, the use effect of the novel chlorella-loaded coconut shell active carbon (Csac-Chlorella) is greater than the sum of the heavy metal adsorption effects of the single use of the coconut shell active carbon and the single use of the chlorella, such that the research results show that the novel chlorella-loaded coconut shell active carbon (Csac-Chlorella) has a certain removal effect on the heavy metal pollutants in the wastewater, and has the potential of heavy metal pollution wastewater remediation.

Description

technical field [0001] The invention belongs to the field of biotechnology, and in particular relates to a novel chlorella-loaded coconut shell activated carbon adsorbent and a preparation method and application thereof. Background technique [0002] Microalgae is a common microorganism in various water bodies. It reproduces quickly and has strong adaptability. It only needs to inoculate a small amount of microalgae mother liquor in the water body. After a period of reproduction in a suitable environment, the amount of microalgae can reach the level of sewage treatment. desired concentration. Sewage is rich in nitrogen and phosphorus, which provides good inorganic nutrients for the reproduction of microalgae. In addition, microalgae can use photosynthesis to obtain carbon sources and energy, and there is no need to provide additional carbon sources to ensure the growth of microalgae, reducing costs. Therefore, the use of microalgae to treat sewage is an effective and econo...
