Embodiment 1

[0031] Such as figure 1 Shown, a kind of processing technique for the enteromorpha of sewage treatment comprises the steps:

[0032] (1) Enteromorpha pretreatment

[0033] Use the Enteromorpha fishing device to catch fresh Enteromorpha, and use seawater to wash it to remove impurities such as sediment;

[0034] (2) pickling

[0035] Using a hydrochloric acid solution with a mass fraction of 5% to soak the Enteromorpha treated in step (1), remove metal ions such as calcium, magnesium, and sodium adsorbed on the Enteromorpha, and increase the adsorption point of the Enteromorpha;

[0036] (3) Anti-corrosion treatment

[0037] Immerse the Enteromorpha treated in step (2) into a sodium dehydroacetate solution with a mass fraction of 0.01%, and soak for 0.5h to increase the antiseptic performance of the Enteromorpha;

[0038] (4) Alkaline treatment

[0039] Wash the Enteromorpha after the antiseptic treatment in step (3), immerse it in a sodium hydroxide solution with a mass f...

Embodiment 2

[0045] A processing technology for Enteromorpha for sewage treatment, comprising the steps of:

[0046] (1) Enteromorpha pretreatment

[0047] Use the Enteromorpha fishing device to catch fresh Enteromorpha, and use seawater to wash it to remove impurities such as sediment;

[0048] (2) pickling

[0049] Using a hydrochloric acid solution with a mass fraction of 8% to soak the Enteromorpha treated in step (1), remove metal ions such as calcium, magnesium, and sodium adsorbed on the Enteromorpha, and increase the adsorption point of the Enteromorpha;

[0050] (3) Anti-corrosion treatment

[0051] Immerse the Enteromorpha treated in step (2) into a sodium dehydroacetate solution with a mass fraction of 0.05%, and soak for 0.7h to increase the antiseptic performance of the Enteromorpha;

[0052] (4) Alkaline treatment

[0053] Wash the Enteromorpha after the antiseptic treatment in step (3), immerse it in a sodium hydroxide solution with a mass fraction of 4%, and alkalize it...

Embodiment 3

[0059] A processing technology for Enteromorpha for sewage treatment, comprising the steps of:

[0060] (1) Enteromorpha pretreatment

Abstract

The invention discloses a processing technology of Enteromorpha used for sewage treatment, comprising the following steps: (1) Enteromorpha pretreatment (2) pickling (3) anticorrosion treatment (4) alkalization treatment (5) immobilization treatment (6) Post-treatment, Enteromorpha after the process of the present invention has better filtering effect and adsorption performance, and large adsorption capacity, as an adsorption material in the sewage treatment system, it can effectively remove heavy metal ions and organic pollution in sewage It can remove pollutants and inorganic pollutants, purify water quality, and greatly improve the anti-corrosion performance. It can be replaced regularly, and will not cause secondary pollution due to the corruption of Enteromorpha.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, in particular to a processing technology of enteromorpha used for sewage treatment. Background technique [0002] In the traditional sewage treatment process, additives such as organic flocculants and inorganic flocculants are usually used to settle and remove pollutant particles in sewage, and some adsorbents such as activated carbon are used to adsorb pollutants and heavy metal ions in sewage, but these flocculants, adsorption Agents, etc. are non-renewable or difficult to regenerate, and the cost is high for long-term use. [0003] Enteromorpha is a kind of green algae. The algae are bright green and consist of a single layer of cells, which are surrounded by tubes or adhered into ribbons. Under the microscope, there are often many air sacs in the algae of Enteromorpha. Due to global climate change, water eutrophication and other reasons, the "green tide" of marine algae Enteromorpha...
