Abstract

The invention relates to a method for efficiently treating pig cultivation waste water and belongs to the technical field of treatment of pig cultivation waste water. The method comprises the following steps: building a filtering pool with a water inlet pump at the top, paving aeration pipes at the bottom, connecting the aeration pipes with an aeration machine outside the filtering pool, mounting microporous aeration heads on the aeration pipes, paving an ecological filter cake, arranging a water outlet above the aeration pipes, connecting the water outlet with a water outlet pipe, connecting the water outlet pipe with a cultivation pool with a water pumping machine, paving nutritional soil, arranging a stirrer in the middle of the nutritional soil, connecting the stirrer with a television, pouring pig cultivation waste water into the filtering pool, starting the aeration machine, turning on the television after the waste water enters the cultivation pool, closing a valve and turning off the television when the water level reaches certain height, removing plants after plants are planted for certain time, and pumping water in the cultivation pool to finish treatment on the pig cultivation waste water. According to the treatment method provided by the invention, the treatment effect is not influenced by season or temperature change, underground water is not polluted, energy consumption is low, the needed mechanical equipment is less, and the maintenance management quantity is small.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment, and in particular relates to a method for efficiently treating pig raising waste water. Background technique [0002] With the increasingly large-scale operation of pig farming, the problems caused by pig farm wastewater are becoming more and more serious, which is one of the main factors that form agricultural non-point source pollution. Pig farm wastewater is a high-concentration organic wastewater produced by liquid metabolites discharged from pigs and flushing solid manure and residual feed during intensive pig farm feeding. The quality and quantity of wastewater is directly related to the production method of the pig farm. At present, the main manure cleaning processes in large-scale pig farms include water flushing, water soaking manure and dry manure cleaning processes. Nowadays, most large-scale pig farms use water flushing technology. A 10,000-head pig farm uses water to...
