Solar micro-power method and system for treating pig farm biogas slurry biological matrix

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...

Problems solved by technology

[0003] The purpose of the present invention is to solve the outstanding problems of high cost of pig farm biogas slurry treatment project and large wetland area, and to provide a treatment method for large-scale pig farm wastewater using solar micro-aeration device. The method is On the basis of the bio-matrix consumption system, the solar panel device is used to provide energy for the micro-aeration equipment according to local conditions, and the removal rate of the bio-matrix system for pig wastewater pollutants is enhanced, and the removal rate of COD, TN, and TP can reach 40%. ~50%, laying a good foundation for the further use of ecological wetlands to treat wastewater. On the basis of increasing a small amount of engineering costs and not increasing operating costs, the wetland area can be greatly reduced by more than 20%.
