specific Embodiment approach 1

[0020] Embodiment 1: This embodiment is a method for preparing an eco-adsorption column dedicated to treating dairy cow breeding wastewater, which is specifically prepared according to the following steps:

[0021] 1. Cutting: remove the branches and leaves of the corn stalks and the core of the corn stalks, and then cut the corn stalks to obtain corn stalks with a length of 2cm to 4cm; use distilled water to wash the corn stalks with a length of 2cm to 4cm for 5 to 8 times, Then drying at a temperature of 45° C. to 55° C. for 8 hours to 12 hours to obtain dry corn stalks with a length of 2 cm to 4 cm;

[0022] 2. Soaking: Soak dry corn stalks with a length of 2cm to 4cm in a sulfuric acid solution with a mass fraction of 8% to 15% for 15min to 20min to obtain corn stalks soaked in sulfuric acid solution; soak corn stalks in sulfuric acid solution Soak in a potassium phosphate solution with a mass fraction of 30% to 50% for 40 to 50 minutes to obtain corn stalks soaked in the ...

specific Embodiment approach 2

[0033] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the material of the adsorption column described in step 6 is organic glass. Other steps are the same as in the first embodiment.

specific Embodiment approach 3

[0034] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is: step 1 removes the branches and leaves of corn stalks and the core of corn stalks, and then cuts the corn stalks to obtain corn stalks with a length of 2 cm; The corn stalks with a length of 2 cm are washed with distilled water for 5 to 6 times, and then dried at a temperature of 45° C. to 50° C. for 10 h to 12 h to obtain dry corn stalks with a length of 2 cm to 4 cm. Other steps are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a preparation method of a special ecological absorption column for treating cow breeding waste water, and relates to a preparation method of an ecological absorption column. The preparation method aims to solve the problem that an existing method for treating the cow breeding waste water is high in operating cost and poor in treatment effect and is inappropriate for deep treatment of the cow breeding waste water. The preparation method comprises the following steps: cutting corn stalks, soaking the corn stalks with a sulfuric acid solution, then soaking with a potassium phosphate solution, then carrying out activation, sieving, then soaking with a cellulolytic enzyme solution, then adding a sodium alga acid solution, then dropwise adding a calcium chloride solution, leaving to stand, and washing to obtain active carbon fixed with mixed enzyme; washing zeolites by using grain size nitric acid, then soaking the zeolites with nitric acid, then washing, and drying to obtain treated zeolites; adding the active carbon fixed with mixed enzyme and the treated zeolites into the absorption column. The ecological absorption column prepared by using the preparation method is suitable for treating the cow breeding waste water.

Description

technical field [0001] The invention relates to a preparation method of an ecological adsorption column. Background technique [0002] With the transformation of the aquaculture industry from traditional small-scale production to intensive and large-scale production, it is accompanied by excessive concentration of carbon, nitrogen, and phosphorus-rich manure and fence waste water, which also puts great pressure on the environment. In many areas, the pollution caused by livestock and poultry breeding has become or is becoming the main local pollution source. Therefore, in response to these problems, the state has issued a series of policies in recent years to vigorously strengthen the construction of large and medium-sized biogas projects for large-scale livestock and poultry farms. When large and medium-sized biogas projects process livestock and poultry waste and produce biogas, a large amount of by-product, biogas slurry, will also be produced. Because after anaerobic fer...
