Embodiment 1

[0054] according to Figure 2A and Figure 2B It can be seen that a kind of solar energy micro-power pig farm biogas slurry biological matrix treatment method, its steps are:

[0055] A. Build a biological matrix pool: build a biological matrix pool, mainly through biological matrix materials (straw, corn stalk, wheat straw, etc.) to degrade wastewater COD and absorb nitrogen and phosphorus. The specifications of the biological matrix pool are determined according to the number of pigs in stock. The technical parameters and space layout requirements of the matrix pool mainly include:

[0056] 1) The depth of the biomatrix pool is 200 or 220 or 235 or 250cm, and the volume requirement is 0.2 or 0.3m 3 / head of pigs in stock. The biological matrix pool is divided into 3 or 4 grades on the basis of ensuring the total volume.

[0057] 2) The wall and bottom of the biomatrix pool are required to have an anti-seepage function. The wall material is a brick-concrete structure wit...

Embodiment 2

[0077] according to Figure 2A , Figure 2B , image 3 It can be seen that a treatment system utilizing a solar micro-aeration device to treat large-scale pig farm wastewater includes a No. 1 solar micro-aeration device 1A, a first-level biological matrix pool 2A, and a biological matrix material 5. The connection relationship is: two The first-level biological matrix pool 2B is connected to the first-level biological matrix pool 2A and the third-level biological matrix pool 2C respectively, the third-level biological matrix pool 2C is connected to the fourth-level biological matrix pool 2D, and the first-level biological matrix pool 2A, The secondary biomatrix pool 2B, the tertiary biomatrix pool 2C, and the quaternary biomatrix pool 2D are connected to each other by diversion holes 4 in a transversal layout. Corresponding aeration discs 14 are housed in the matrix pool 2B, the third-level biological matrix pool 2C, and the fourth-level biological matrix pool 2D. , 2C, 2D)...

Abstract

The invention discloses a solar micro-power method and system for treating a pig farm biogas slurry biological matrix.The method comprises the following steps: A, building biological matrix pools, comprising: 1) building the biological matrix pools, 2) performing seepage prevention of the wall bodies and the bottoms of the biological matrix pools, 3) adjoining the first to fourth stages of the biological matrix pools, and 4) newly building a biological matrix pool; B, solar micro-aeration system designing and installing, comprising: 1) selecting and installing a solar micro-aeration machine, 2) designing and installing a solar cell panel and a storage battery, 3) designing and installing a time controller, (4) mounting a tool box, and (5) designing and installing an aeration disc; C, addition of a matrix material into a matrix digestion pool; and D, operation and management of the micro-aeration biological matrix treatment system. The system comprises the solar micro-aeration device, the biological matrix pools and a biological matrix material. The method is easy to implement, simple to operate, low in cost, good in treatment effect, simple in structure and convenient to use, and the occupied area of the sewage treatment system is greatly reduced.

Description

technical field [0001] The present invention relates to the field of agricultural environment, more specifically to a method for treating biogas slurry waste pollutants in pig farms, and also to a biogas slurry waste pollutant treatment system in pig farms, especially suitable for raising pigs in areas south of the Yellow River in China Ecological treatment of biogas slurry. Background technique [0002] The environmental pollution caused by biogas slurry discharge from pig farms is the main bottleneck problem affecting the healthy development of pig breeding industry. Generally, the treatment methods of biogas slurry mainly include two forms of fertilizer and water irrigation and discharge after treatment. Among them, the utilization of biogas slurry has a good effect on the wastewater treatment of small-scale farmers, but for large-scale farms, due to the large amount of wastewater discharge, Coupled with the limitations of the insufficient land area available for the far...
