Abstract

The invention relates to a treatment system and a treatment process for waste liquid in a dried melon reducing sugar production process. A waste liquid storage tank of the treatment system is connected with one end of a diversion tank, the bottom end of the diversion tank is communicated with the bottom of a multistage aerobic and anaerobic system, the top of a last-stage aerobic tank of the three-stage aerobic and anaerobic system is connected with a biological fluidized bed, the other end of the biological fluidized bed is connected with a ceramic membrane sewage treatment device, and sludge separation outlets of the biological fluidized bed, the ceramic membrane sewage treatment device and the three-stage aerobic and anaerobic system are all connected to an active sludge separation concentration device. The waste liquid flows through the diversion tank and is sequentially treated by the multistage aerobic and anaerobic system, the biological fluidized bed and the ceramic membrane sewage treatment device, then the treated waste liquid is recycled as size mixing water, and sludge produced by the system is concentrated and dried to form dried sludge. The treatment system and the treatment process have the characteristics of high environment friendliness, high resource utilization rate, high treatment effect, strong impact resistance and full-automatic control.

Description

technical field

[0001] The invention belongs to an environmental protection treatment technology and relates to the treatment and reuse of high-concentration organic waste water. In particular, it relates to an anaerobic-aerobic-biological fluidized bed co-treatment process system for the whole waste of dried melon reducing sugar production waste liquid. Background technique

[0002] my country is a big producer of reducing sugar. The production process is mainly based on the hydrolysis of starchy raw materials. As the main raw material for the development of reducing sugar production, dried melon is a low-cost non-grain raw material that can be planted on a large scale at the present stage. It has a good development prospect. However, the waste liquid in the production process is a kind of high-concentration organic wastewater, and its main components are undecomposed starch, fiber and pectin. Maintained at about 4, the production of each ton of reducing sugar will produce...
