Method for purifying liquid manure using the ground, with denitrification of the water percolated through using new liquid manure

摘要

Method for purifying liquid manure using the ground. The spreading doses envisaged greatly exceed the capability of plants to use the nitrogen-containing substances. The ground compartment 2A-2B is used for nitrification 2-2. The residual nitrates are washed in a period of excess water, an arrangement of the ground makes it possible to collect them 3. Denitrification using liquid manure again is implemented in a reactor 5. The denitrifying flora comes from the liquid manure 1. The final effluent without nitrate is again spread 5-1. The system thus provides a means of purifying liquid manures without polluting underground waters with nitrates.
