Problems solved by technology

[0004] The technical problem to be solved by the present invention: Aiming at the drawbacks that the sludge and nitrifying liquid need to be refluxed in the treatment of livestock and poultry breeding sewage by the above method, resulting in complicated operation process and high operation cost, a method for treating livestock and poultry breeding sewage is provided. Circulating biological selective reactor, this method does not need to reflux the livestock and poultry breeding sewage sludge and nitrification liquid, and the three phases are separated in different directions, so that the three phases can be separated more thoroughly

example 1

[0025] The livestock and poultry breeding sewage enters the anaerobic first zone (10) in the reactor body (2) through the water inlet (4), the sewage is evenly distributed through the water distribution plate (3), and part of the sludge flows upward from the inclined plate (16 ) falls into the bottom of the tray to realize the separation of mud and water, and the increased part of the sludge overflows the overflow outer plate (6) and directly falls into the sewage collection tank (17) from the central channel, and the anaerobic sewage overflows the overflow inner plate ( 8) Connect the pipeline to the biological selection area (5). After the biological selection, the sewage enters the biological aerobic area (11) from the bottom of the biological selection area (5), aerates for 2 hours, and the water overflows the overflow inner plate (8) It is introduced into the anaerobic second zone (12) through the pipeline for denitrification, and the remaining sludge partly overflows the ...

Abstract

The invention discloses a circulating biological selection reactor for livestock and poultry culture sewage treatment. The reactor is mainly composed of a gas outlet, a reactor body, a water inlet, a sewage collecting pool and a water outlet, livestock and poultry culture sewage enters an anaerobic zone 1 through the water inlet and undergoes anaerobic denitrification, sludge in an incremental portion directly falls into the sewage collecting pool, anaerobic sewage overflows an overflow external plate, overflowed sewage is directly introduced to a biological selection zone 1 through a pipeline and undergoes biological adaptation, obtained sewage enters a biological aerobic zone 1 and undergoes selective biological aeration treatment, a nitration solution directly enters an anaerobic zone 2 and undergoes denitrification, cycle treatment is carried out, a gas is discharged from the gas outlet, sewage obtained after biological aerobic zone 3 treatment goes through a water fender, obtained water is drained from the water outlet, and sludge in the sludge collecting pool is discharged through a sludge pump. The reactor has the advantages of no refluxing of sludge or the nitration solution, realization of phosphorus removal through repeated anaerobic and aerobic treatment of sludge, direct falling of incremental and residual sludge to bottom without sludge discharge, and realization of thorough separation of three phases positioned in different directions.

Description

technical field [0001] The invention relates to a circular bioselective reactor for sewage treatment of livestock and poultry breeding, which belongs to the technical field of sewage treatment. Background technique [0002] With the adjustment of my country's agricultural structure and the advancement of agricultural industrialization, the poultry and livestock breeding industry has developed rapidly in scale and intensification, and the resulting pollution problems have become increasingly serious, which has had a serious impact on regional environmental quality. The pollution of air, surface water and groundwater in the basin has been quite serious. The concentration of organic matter in livestock breeding sewage is high and the water quality fluctuates greatly, which has become one of the main causes of rural pollution in my country. The lives of humans and animals also affect human food safety. [0003] At present, the method of treating poultry breeding sewage is through...
