Embodiment Construction

[0012] in the attached Figure 1 In the process, the aquaculture biogas slurry waste liquid that has been filtered in the early stage flows into the integrated aquaculture sewage treatment machine (10) from the sewage water inlet (6), and undergoes multiple biochemical reaction treatments, sedimentation filtration, disinfection and other processes in the integrated machine, and the sewage treatment The clean water reaching the standard is discharged from the clean water outlet (7), wherein the sedimented and filtered biochemical reaction sludge is stored in the sludge pool (4), and the sludge therein is cleaned regularly through the sludge extraction port (9).

[0013] in the attached Figure II In the process, the sewage enters the primary oxidation tank (1), which contains high-efficiency biological composite fillers to fully take place the hydrolytic acidification reaction to decompose the large particles of organic matter in the sewage. After fully reacting, the primary ox...

Abstract

The invention provides an integrated farming sewage treatment apparatus. The treatment apparatus is specially used for treatment of waste biogas slurry obtained after biogas fermentation of cultivation sewage produced in pig farming. The apparatus is of a box type integrated structure; two sides of the apparatus are respectively provided with a sewage inlet and a purified water outlet; the top of the apparatus is provided with four inspection openings and one sludge extraction opening; a primary oxidation tank, a secondary oxidation tank, a secondary sedimentation tank, a sludge tank and a sand filtration disinfection tank are successively arranged in the apparatus, and the apparatus is equipped with aeration devices for respective aeration of the primary oxidation tank and the secondary oxidation tank; waste biogas slurry fermentation liquid enters into the apparatus from the sewage inlet, undergoes treatment by each part in the apparatus and is discharged from the purified water outlet when reaching discharge standards; sludge in the sludge tank is extracted from the sludge extraction opening at regular intervals by a worker.

Description

Technical field [0001] The present invention involves a processing device for a integrated breeding sewage and a biogya wastewater for the fermentation of waste liquid, especially the modular equipment to deal with farming sewage. Background technique [0002] At present, the treatment of wastewater and breeding waste liquid biogas fermentation waste liquid is a major problem faced by the modern breeding industry. The organic matter content in the sewage is high, the COD, the BOD value is relatively high, and the concentration is relatively high.Heavy metal ions are required to achieve strict treatment to meet the national emission standards.At present, the sewage treatment technology often used is the "A / O biological contact oxidation" process. The processing process is relatively simple, the operation is easy to operate, the daily cost is low, and the water is stable.Usually sewage treatment projects need to be built up to build a acid solution pool, secondary oxidation pool, t...
