Embodiment Construction

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0020] See figure 1 As shown, the present invention provides a technical solution: a SBR wastewater treatment process for soybean lecithin production, including the following steps:

[0021] (1) Pretreatment slag removal: Before entering the corresponding grease trap, the waste water is lifted to remove the larger particles of suspended solids / slag and surface oil in the water body.

[0022] (2) Pretreatment of slick oil: the raw water afte...

Abstract

The invention discloses an SBR (Sequencing Batch Reactor) activated sludge process for soybean lecithin production. The process comprises the following steps: performing pretreatment sludge fishing, pretreating floating oil, adjusting water quantity in an adjusting tank, homogenizing water quality, performing coagulation air floating treatment, performing acidification conditioning in a hydrolysisacidification tank, and performing aerobic treatment in an integral bioreactor. The process disclosed by the invention is concise in process, efficient in solid-liquid separation, excellent and stable in effluent quality, capable of removing ammonia nitrogen and refractory organic matters and overcoming defects that sludge expansion can be easily caused when a conventional activated sludge process is used, small in floor space, free of secondary sedimentation tank and centralized in process equipment.

Description

Technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to a SBR wastewater treatment process produced by soybean lecithin. Background technique [0002] A lot of waste water is generated during the production of soybean lecithin. The waste water mainly comes from workshop floor washing waste water, equipment washing waste water, long-term initial rainwater and boiler soft water to prepare concentrated water, among which equipment washing water and workshop washing water contain high-concentration organic wastewater. Pure water and softened water are acid wastewater. According to the existing experience, the current waste treatment process is longer and the operation operation is more troublesome; the pretreatment of the wastewater treatment system is relatively simple, resulting in higher compliance with subsequent biochemical treatment, higher energy consumption, unstable operation, and no backwashing. Completely lead to the f...
