Problems solved by technology

[0007] The technical problem mainly solved by the present invention: In view of the high concentration of organic matter, more suspended solids and excessive ammonia nitrogen content in the current poultry wastewater, it is difficult to meet the corresponding discharge standards by using the commonly used wastewater treatment methods for poultry farming, and the impact of farmland soil compaction Yield, the commonly used deep tillage method has the disadvantages of short-term operation and cumbersome operation process. It provides a method of using poultry breeding wastewater to treat soil compaction.
The invention not only has simple operation, low cost and no secondary pollution, but also solves the problem of soil compaction and has economic benefits

example 1

[0020]First dig a sewage treatment tank with a length of 15m, a width of 10m and a height of 2.5m, introduce the poultry breeding wastewater into the sewage treatment tank, stop the introduction of the poultry breeding wastewater when the water level reaches 2.0m, and then add the bottom of the anaerobic tank to the treatment tank The volume ratio of the activated sludge to the sewage treatment tank is 1:6, and then an aeration device is installed at the bottom of the tank to perform aeration treatment, so that the activated sludge at the bottom of the anaerobic tank and the poultry breeding wastewater are fully mixed Evenly, in a suspended state; then according to the mass fraction, take 20 parts of fresh lavender, 30 parts of Pangpengxiang, and 35 parts of Fenbaicao into clean water, wash it repeatedly once, remove surface dirt, and let it dry naturally Finally, mash it into slag, then put the plant leaf slag obtained after mashing into a fermenter, place it in a ventilated a...

Abstract

The invention discloses a method using poultry cultivation waste water to process soil hardening and belongs to the field of waste water treatment. The method includes: guiding activated sludge in an anaerobic tank into a treatment tank with the poultry cultivation waste water, well mixing, then adding extracted plant extract into the treatment tank to obtain mixed liquid, performing anaerobic fermentation on the mixed liquid until black mixed turbid liquid is obtained, and guiding the black mixed turbid liquid into perforated hardened soil to solve the soil hardening problem. Practical examples prove that the method has economic benefits and is simple and practicable, low in cost, free of secondary pollution and capable of solving the soil hardening problem.

Description

technical field [0001] The invention discloses a method for treating soil compaction by using poultry breeding wastewater, which belongs to the field of wastewater treatment. Background technique [0002] The effective management of aquaculture waste has become one of the three major problems plaguing the world's environmental workers. In terms of its emissions, its organic matter COD equivalent emissions are twice that of industrial and urban domestic wastes. What's worse is that industrial and urban domestic wastes have been effectively treated, while the treatment of breeding wastes in our country is still under the condition of under-treatment or simple treatment. [0003] Poultry farm wastewater mainly includes urine, feces and breeding house flushing water. This type of wastewater has a high concentration of organic matter, its COD is 5000-13000mg / L, BOD is 5000-6000mg / L, and there are many suspended solids. SS is 17000-20000mg / L , the content of ammonia nitrogen is h...
