Embodiment Construction

[0016] A large-scale pig farm adopts IC + SBBR + UASB combined process to treat pig wastewater. The effluent from the SBBR pool flows into the UASB reactor. After being treated by UASB, pollutants such as COD, ammonia nitrogen and nitrite nitrogen in the wastewater are further removed. After the wastewater is treated, the effluent quality meets the requirements of GB 18596-2001 "Discharge Standard of Pollutants for Livestock and Poultry Breeding Industry". UASB effluent COD 100 mg / L, NH 3 -N 40~80mg / L.

[0017] The specific implementation process is as follows:

[0018] (1) After the pig farm wastewater is collected by the sewage collection pipe network, it is intercepted by the mechanical grille to remove large particles of pollutants and floating objects in the sewage, and the wastewater enters the IC reactor.

[0019] (2) The waste water enters the IC reactor, undergoes high-efficiency anaerobic digestion, and after removing most of the COD to obtain biogas, the water qual...

Abstract

The invention discloses a novel up-flow anaerobic sludge blanket (UASB) for treating wastewater of a pig farm, which comprises a UASB reactor main body, a raw water tank, a heating and heat insulation system, a control cabinet, a water inlet system, a reflux system and the like. A bio-film filler fixed bracket is arranged in the reactor, a bio-film filler is arranged on the filler fixed bracket, and the operation of the whole reactor is controlled through an electromagnetic metering pump. The reactor has the characteristic of simultaneously degrading organic substances and ammonia nitrogen, and is suitable for automatic control of the whole process.

Description

technical field [0001] The invention relates to environmental engineering technical equipment, in particular to a UASB (Up-flow Anaerobic Sludge Bed, hereinafter referred to as UASB) reactor for synchronous anaerobic ammonium oxidation methanation and denitrification of pig farm wastewater . Background technique [0002] Livestock and poultry breeding wastewater, especially large-scale pig farming wastewater, has become the main source of pollution in many areas of our country. At present, most pig farms use solid-liquid separation-anaerobic-aerobic treatment of fecal wastewater. UASB consists of three parts: sludge reaction zone, gas-liquid-solid three-phase separator (including sedimentation zone) and air chamber. A large amount of anaerobic sludge remains in the bottom reaction zone, and the sludge with good sedimentation and coagulation properties forms a sludge layer in the lower part. The sewage to be treated flows from the bottom of the anaerobic sludge bed and is ...
