Abstract

A water treatment composition for treating organic wastewater is provided. The water treatment composition includes a bulk catalytic material and an oxidant. The bulk catalytic material includes iron atoms or ions, manganese atoms or ions, and magnesium atoms or ions.

First claim

What is claimed is:

1 . A water treatment composition for treating organic wastewater, the water treatment composition comprising:
a bulk catalytic material, comprising iron atoms or ions, manganese atoms or ions, and magnesium atoms or ions; and an oxidant.

2 . The water treatment composition of claim 1 , wherein a particle size of the bulk catalytic material is 0.5 cm to 4 cm.

3 . The water treatment composition of claim 1 , wherein in the bulk catalytic material, a content of the iron atoms or ions is 0.1 mg/g to 1 mg/g, a content of the manganese atoms or ions is 0.1 mg/g to 1.5 mg/g, and a content of the magnesium atoms or ions is 2 mg/g to 6 mg/g.

4 . The water treatment composition of claim 1 , wherein a concentration of organics in the organic wastewater is 10 ppm to 1000 ppm.

5 . The water treatment composition of claim 1 , wherein the water treatment composition and the organic wastewater are mixed to form a treatment solution, in the treatment solution, a concentration of the oxidant is 0.01 g/mL to 0.3 g/mL, and a concentration of the bulk catalytic material is 0.01 g/mL to 0.5 g/mL.

6 . The water treatment composition of claim 1 , wherein the oxidant is hydrogen peroxide, ozone or sodium hypochlorite.

7 . The water treatment composition of claim 1 , wherein the bulk catalytic material is an industrial waste.

8 . A water treatment method, comprising:
providing a water treatment composition, wherein the water treatment composition comprises a bulk catalytic material and an oxidant, the bulk catalytic material comprises iron atoms or ions, manganese atoms or ions, and magnesium atoms or ions; and mixing the water treatment composition with organic wastewater, so as to decompose organics in the organic wastewater.

9 . The water treatment method of claim 8 , wherein the water treatment composition and the organic wastewater forma treatment solution, and the water treatment method further comprises:
introducing a current into the treatment solution, so as to cause the treatment solution to generate an electrolysis reaction.

10 . The water treatment method of claim 9 , further comprising:
converting thermal energy generated by the electrolysis reaction into electrical energy via a thermoelectric unit, and using the electrical energy to generate the current introduced into the treatment solution.
