Embodiment 1

[0014] A method for removing synthetic musk from water, comprising the steps of:

[0015] Step 1. Import the sewage containing synthetic musk into the aerobic hydrolysis-MBR membrane bioreactor for treatment, and the hydraulic retention time is 5h;

[0016] Step 2: import the sewage treated in the step 1 into the reaction tank, add an appropriate amount of activated carbon, stir and adsorb for 24 hours, let it settle for 40 minutes, and the clear liquid is the treated sewage.

[0017] The amount of activated carbon added is: 0.3 g of activated carbon is added to every liter of sewage; the rotational speed of stirring and adsorption is 80 rpm / h.

Embodiment 2

[0019] A method for removing synthetic musk from water, comprising the steps of:

[0020] Step 1. Import the sewage containing synthetic musk into the aerobic hydrolysis-MBR membrane bioreactor for treatment, and the hydraulic retention time is 7h;

[0021] Step 2: import the sewage treated in step 1 into the reaction tank, add an appropriate amount of activated carbon, stir and adsorb for 30 hours, and let it settle for 50 minutes. The clear liquid is the treated sewage.

[0022] The amount of activated carbon added is: 0.5 g of activated carbon is added to every liter of sewage; the rotational speed of stirring and adsorption is 100 rpm / h.

Embodiment 3

[0024] A method for removing synthetic musk from water, comprising the steps of:

[0025] Step 1. Import the sewage containing synthetic musk into the aerobic hydrolysis-MBR membrane bioreactor for treatment, and the hydraulic retention time is 10h;

[0026] Step 2: import the sewage treated in the step 1 into the reaction tank, add an appropriate amount of activated carbon, stir and adsorb for 36 hours, let it settle for 60 minutes, and the clear liquid is the treated sewage.

[0027] The amount of activated carbon added is: 0.7 g of activated carbon is added to every liter of sewage; the rotational speed of stirring and adsorption is 120 rpm / h.

Abstract

The invention discloses a method for removing synthetic musk in water. The method for removing synthetic musk in water comprises the following steps: introducing sewage containing synthetic musk intoan aerobic hydrolysis-MBR membrane bioreactor for treatment; introducing the treated sewage into a reaction tank, adding a proper amount of active carbon, stirring and adsorbing for 24-36h, standing and precipitating for 40-60 min, and obtaining a clear liquid, namely treated sewage. The method for removing synthetic musk in water has advantages of short treatment time, obvious treatment effect and low treatment cost.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for removing synthetic musk in water. Background technique [0002] Because the production of natural musk is limited by its production method and cannot keep up with people's increasing demand for musk, so people have found a method to utilize chemical means to synthesize musk, that is, to replace natural musk with synthetic musk. As a cheap substitute for natural musk, synthetic musk is widely used in the daily chemical industry because of its excellent fragrance-fixing ability, typical musk fragrance and low price. [0003] Synthetic musk is added to cosmetics and detergents as a fragrance, and after use these products cleanse the skin and release the pollutants into sewage. Due to the extensive use of these compounds, synthetic musk enters the environment along with sewage. Synthetic musk has been detected in surface water, sewage, sludge, air, and aquatic...
