[0048] 2) Preparation of Radix Radix Radix Dregs

[0049] Cut the purchased Radix isatidis into small pieces of about 1 cm, fry it in water for 3 times, take it out and dry it after 30 minutes each time, this process is to simulate the production process of traditional Chinese medicine dregs.

Embodiment 1

[0050] Example 1 Preparation of adsorbent by different chemical modifications using Radix isatidis dregs

[0051] 1) Decolorization treatment of Radix Radix Radix Slag: First, dry and pulverize Radix Radix Radix Radix Slag residue, pass through a 60-mesh sieve, then put it into a beaker, add methanol at a ratio of 1:5 (w / v), and place it on a magnetic stirrer. Stir at a speed of 500r / min, change the methanol every 12h until the dregs are white, dry at 65°C to constant weight, and store for later use.

[0052] 2) Chemical modification: take 5 parts of decolorized isatidis slag each 10mg, add 100ml of 1mol / L HCl, 1mol / L NaOH, 1mol / L NaCO respectively 3 , 1mol / L H 2 SO 3 , 0.6mol / L citric acid, shake in a constant temperature oscillator at a rate of 120r / min for 4h (HCl, NaOH, NaCO 3 ), 24h(H 2 SO 3 ), 30min (citric acid), and then filtered, and the solid residue was repeatedly washed with deionized water until the pH was about 7, and dried in an oven at 60°C until constant ...

[0054] Example 2 Preparation of adsorbent by using Radix isatidis dregs through different weight ratios of Radix isatidis and potato starch

[0055] 1) Decolorization treatment of Chinese medicine Radix Radix Slag: First, dry and pulverize the traditional Chinese medicine Radix Radix Radix Slag, pass through a 60-mesh sieve, then put it into a beaker, add methanol at a ratio of 1:5 (w / v), and put it on a magnetic stirrer. Stir at a speed of 500r / min, change the methanol every 12h until the dregs are white, dry at 65°C to constant weight, and store for later use.

[0056] 2) Biological fermentation: mix 100 g of fermentation substrate with 30 g of water and 0.1 g of ammonium sulfate, wherein the fermentation substrate is made of Radix Radix Radix dregs and potato starch in a weight ratio of 3:1, 3:2, 2:1, and 1 :1, 2:3 mixed, sterilized in a sterilizing pot at 121°C for 20 minutes, cooled, and used as a medium.

[0057] Then inoculate the white rot fungus liquid in the sterili...

Abstract

The invention discloses a traditional Chinese medicine isatis root residue water treatment agent, and a preparation method and application thereof, and belongs to the technical field of water treatment agents. The problem that existing wastewater and traditional Chinese medicine residues urgently need to be treated is effectively solved. The traditional Chinese medicine isatis root residue water treatment agent is prepared by sequentially carrying out NaOH modification and white-rot fungus fermentation treatment on isatis roots which are decocted with water. The method comprises the followingspecific steps: firstly, decolorizing the traditional Chinese medicine isatis root residues; then adding NaOH into the decolorized isatis root residues to carry out chemical modification; mixing the chemically modified isatis root residues with carbon source and water, cooling, sterilizing, adding white-rot fungi to inoculate, and fermenting; and finally, filtering out a solid from a fermentationproduct, and drying the solid to obtain the water treatment agent. The water treatment agent has the following beneficial effects: the isatis root residues are used as a raw material to prepare a biological adsorbent through a chemical and biological double-treatment method, and the isatis root residues which are Chinese herbal medicine wastes are used for treating wastewater, so that the utilization rate of resources can be effectively improved, and the environmental pollution is reduced.

Description

technical field [0001] The invention belongs to the technical field of water treatment agents, and in particular relates to a traditional Chinese medicine Radix Radix Radix Slag water treatment agent and its preparation method and application. Background technique [0002] In my country, the discharge of sewage and wastewater is about 1×10 per day 8 m 3 As many as 82% of the rivers and lakes in the country have been polluted to varying degrees, 2% of the urban drinking water sources are seriously polluted, and 70% of the rural drinking water does not meet the hygienic standards. The economic losses caused by water pollution every year As high as 37.7 billion yuan, the treatment of water pollution is obviously already a very serious problem. [0003] At present, there are three main methods for treating dye wastewater: physical and chemical methods, chemical methods and biochemical methods. Among them, the adsorption method is one of the most mature physical and chemical t...
