Embodiment Construction

[0034] The core process unit of the process is the ABR reactor and aerobic fluidized bed. In view of the characteristics of printing and dyeing and tanning wastewater, all printing and dyeing and tanning enterprises are required to discharge batik wastewater, high-alkalinity wastewater, and three types of wastewater before the wastewater is discharged into the sewer. Wastewater with high chromium, sulfide content or other toxic and harmful pollution indicators in the biochemical process of the sewage treatment plant shall be effectively pre-treated to reach the sewage treatment plant's required discharge index value. The specific process flow of the sewage treatment plant is as follows:

[0035] Raw water → pH adjustment tank → adjustment tank → lift pump → mechanical hydraulic separation screen → (dosing) → coagulation sedimentation tank → ABR hydrolysis (acidification) tank → aerobic biological fluidized bed → sedimentation tank → oxidation contact tank → discharge

Abstract

The invention is mainly used to treat the waste water from high difficulty printing profession, the leather making meatpacking industry's production, which can realize recycling and second-use of the effective resources in production of waste water, and falls the waste water pollution degree to smallest. According to my company in the many years engineering design and the actual movement experience, we summarizes it that suits for the printing, leather making industrial production waste water processing, which has own characteristic of the industrial production waste water processing craft: Adds the coagulation precipitates the ABR reactor + aerobic fluid bed water leakage and achieves the synthesis discharge standard GB8978 - 1996 - best of the standards.

Description

[0001] Technical field: environmental protection technology [0002] Dosing, coagulation and sedimentation + ABR reactor + aerobic fluidized bed treatment of industrial wastewater technology Application fields: printing and dyeing industry, leather processing industry and other production industrial wastewater treatment technical background [0003] Dosing coagulation sedimentation + ABR reactor + aerobic fluidized bed treatment of industrial wastewater technical background: [0004] The industrial production wastewater in the printing and dyeing industry and the tanning industry concentrated industrial park is industrial wastewater that is difficult to treat in China. At present, under the condition of reasonable and feasible technology and economy in China, the effluent after treatment can only reach the industry level II standard. , Bring pollution to the natural environment. [0005] The research topic of this project is to improve the traditional wastewater treatment process i...
