Embodiment 1

[0033] A method for treating livestock and poultry sewage with hydroponic protein grass, comprising the following steps:

[0034] S1. Dilute the livestock and poultry sewage with water, and adjust the pH and conductivity.

[0035] S2. Adding sterilizers and insecticides to the diluted livestock and poultry sewage.

[0036] S3. Adding 1% by volume formulation solution to the livestock and poultry sewage treated in step S2.

[0037] According to mass ratio, the preparation solution includes: 10% biological enzyme, 1% urease, 15% mineral and 1% peroxide, and the rest is water.

[0038] S4. Transplant the protein grass seedlings into the livestock and poultry sewage treated in step S3, and carry out hydroponics.

[0039] S5. Harvest once every 20-30 days of hydroponics.

Embodiment 2

[0041] A method for treating livestock and poultry sewage with hydroponic protein grass, comprising the following steps:

[0042] S1. Dilute the livestock and poultry sewage with water, and adjust the pH and conductivity.

[0043] S2. Adding sterilizers and insecticides to the diluted livestock and poultry sewage.

[0044] S3. Adding 5% of the prepared solution by volume to the livestock and poultry sewage treated in step S2.

[0045] According to the mass ratio, the preparation solution includes: 5% biological enzyme, 3% urease, 5% mineral and 5% peroxide, and the rest is water.

[0046] The biological enzymes include cellulase, pectinase, amylase and catalase.

[0047] The minerals include 0.01 part of silicon, 500 parts of calcium, 100 parts of magnesium, 1000 parts of potassium, 0.8 part of iodine, 0.05 part of selenium, 0.01 part of iron and 0.05 part of molybdenum in parts by weight.

Embodiment 3

[0051] A method for treating livestock and poultry sewage with hydroponic protein grass, comprising the following steps:

[0052] S1. Dilute the livestock and poultry sewage with water, and adjust the pH and conductivity.

[0053] Control the conductivity of the diluted livestock and poultry sewage to 1.0-3.0mS / cm, and control the pH to about 6.5. After the protein grass seedlings are transplanted, the conductivity is controlled to 1.5mS / cm in the first 3 to 7 days; after that, the conductivity is controlled to 2.5mS / cm. Use a water quality detection pen to monitor the conductivity in real time.

[0054] S2. Adding sterilizers and insecticides to the diluted livestock and poultry sewage.

[0055]The sterilant is the German imported Octex plant disinfectant.

[0056] The insecticide is a plant insecticide. The plant insecticide is a plant insecticide produced by Shenzhen Lvsen Biotechnology Co., Ltd.

[0057] S3. Adding a 3% preparation solution by volume to the livestock ...

Abstract

The invention provides a method for treating livestock and poultry sewage by using hydroponic protein grass, and belongs to the technical field of sewage treatment. The method comprises the following steps: S1, diluting the livestock and poultry sewage with water, and adjusting the pH and the conductivity; S2, adding a sterilizing agent and an insecticide into the diluted livestock and poultry sewage; S3, adding a blending solution with the volume ratio of 1%-5% into the livestock and poultry sewage treated in the step S2, wherein the blending liquid comprises the following components in percentage by mass: 5%-10% of biological enzyme, 1%-3% of urease, 5%-15% of mineral substances, 1%-5% of peroxide and the balance of water; S4, transplanting protein grass seedlings into the livestock and poultry sewage treated in the step S3, and carrying out water culture; S5, harvesting once every 20-30 days of water culture. The livestock and poultry sewage is digested and treated by utilizing the hydroponic protein grass, the treated water is used as livestock and poultry production water, the protein grass is recycled to prepare feed, and the overall treatment cost is low.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a method for treating livestock and poultry sewage with hydroponic protein grass. Background technique [0002] Guangxi is a large agricultural province. It is located in the south of China. The Tropic of Cancer runs through the central part. It belongs to the subtropical climate area. It is along the river and the coast. It has good climate and location advantages for the development of the planting and breeding cycle industry. With the development of agriculture, the scale of aquaculture continues to expand, followed by a large increase in manure emissions, and aquaculture pollution has become the largest source of pollution in agricultural production. The animal husbandry industry in the region produces nearly 80 million tons of livestock and poultry manure every year, and more than 200 million tons of manure. However, at present, these manures have not been effectiv...
