Abstract

The invention discloses a farm excrement comprehensive utilization system and method and belongs to the technical fields of environmental protection and waste resource utilization. The farm excrement comprehensive utilization system is in a structure that an excrement soaking tank is sequentially connected with a pretreatment tank, a cutting pump and a metering and heating tank, wherein the metering and heating tank is connected with a CSRT reactor by virtue of a feeding pump, the CSRT reactor is connected with a discharging tank, the discharging tank is connected with a reflux pump, the reflux pump is respectively connected with the excrement soaking tank and a dehydrating machine, the dehydrating machine is respectively connected with a biogas slurry storage device and a biogas residue storage tank, the CSTR reactor is also connected with a water sealing device, the water sealing device is sequentially connected with a steam-water separator, a desulphurization tower, a wet-type gas storage cabinet and an electric generator, and the electric generator is respectively connected with the CSRT reactor and the metering and heating tank by virtue of a heat transfer pipeline. By applying the farm excrement comprehensive utilization system, excrement in a farm can be subjected to hazard-free treatment and resourceful treatment, the environment of the farm is improved, and sustainable development of the farm is promoted.

Description

technical field [0001] The invention belongs to the technical field of environmental protection and utilization of waste resources, and in particular relates to a system and method for comprehensive utilization of farm feces. Background technique [0002] The data show that the pollution of agricultural products in my country's agricultural environment is becoming more and more serious, the environmental quality of cultivated land is declining, and the problem of toxic and harmful substance residues in agricultural products is prominent, which has become an important factor restricting the development of agriculture and rural economy. [0003] Agricultural waste pollution is becoming increasingly prominent. In recent years, while the "vegetable basket" project to enrich urban residents has been successfully implemented, it has also brought about the outstanding problem of environmental pollution caused by a large amount of waste such as livestock and poultry manure and manur...
