Farm excrement treatment process

Abstract

The invention discloses a farm excrement treatment process. The process comprises the following steps: uniformly feeding excrement sewage discharged from livestock raising in a farm into a screening and collecting tank, mixing the excrement sewage and calcium oxide according to a ratio by the collecting tank through a sludge lifting pump, and adding the mixture into a vortex ion accelerator (strong magnetic physical and chemical treatment reactor), performing full treatment, feeding excrement into a static reaction tank for 20-40 minutes, pumping excrement sewage into a solid-liquid separator by using a sludge pump after the reaction is completed, carrying out solid-liquid separation, carrying out air floatation on the separated sewage, carrying out biochemical treatment on supernatant without most suspended solids / eggs / escherichia coli / COD / NH3, enabling concentrated excrement subjected to air floatation to flow into the reaction tank again, and performing secondary solid-liquid separation; making the separated solid excrement into organic fertilizer through an air energy-saving drying machine, and enabling the organic fertilizer to enter the market for selling; treating the liquid into a liquid organic fertilizer, extracting urine protein feed or up-to-standard discharge, collecting waste gas, and preparing or decomposing and discharging a liquid fertilizer through efficient gas-liquid mass transfer technical equipment. Secondary pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of manure treatment, in particular to a farm manure treatment process. Background technique [0002] Feces, urine and sewage easily seep into the ground or flow into rivers, causing drinking water to be polluted by nitrite. Drinking water polluted by nitrite will cause a great threat to human health. The structure of nitrite is similar to that of heme. As a result of its competition with heme, the oxygen-carrying capacity of the blood is reduced, which leads to hypoxia in pregnant women, resulting in blue baby syndrome and brain damage to the fetus. Nitrite can also enter the baby's body through breastfeeding, endangering the health of the fetus. [0003] The aquaculture industry is a high-pollution, high-energy-consuming industry (a large amount of water and food is consumed). In addition to the water for washing animal manure, it also includes other water for animal husbandry. [0004] The bacteria conte...
