Embodiment Construction

[0019] The present invention is further described as follows in conjunction with the accompanying drawings, and embodiments of the present invention are given.

[0020] The integrated MBR sewage treatment and reuse method provided by this technical solution is characterized in that: the pretreated sewage is placed in the same membrane equipped with a string-hanging biological processor, a membrane bioreactor and an aeration mechanism. The anaerobic-aerobic biochemical reaction and ultrafiltration membrane filtration process are carried out simultaneously in the biological reaction purification tank to obtain reusable reclaimed water.

[0021] The biggest feature of the above-mentioned biochemical method of sewage treatment is that the string-mounted biological processor, membrane bioreactor and aeration mechanism are set in the same membrane bioreaction purification tank, so that the sewage treatment technology using biofilm technology can be integrated in the same limited spac...

Abstract

The invention discloses an integral membrane biological reactor (MBR) sewage treating and recycling method, which is characterized in that: pretreated sewage is subjected to anaerobic-aerobic biochemical reaction and biomembrane filtration simultaneously in the same membrane bioreaction purification tank provided with a string hanging type biological treater, a membrane biological reactor and an aeration mechanism to form recycled water. The technology can be widely applied to sewage treatment of catering, chemical engineering, papermaking, printing, landscape ponds, excrement and the like, and the treated water completely meets the emission standard specified by nation and accords with a recycled water recycling index.

Description

technical field [0001] The invention relates to a biofilm sewage treatment technology, in particular to an integral MBR sewage treatment and reuse method and a treatment device, belonging to the sewage treatment and recovery technology category. Background technique [0002] With the development of human civilization in the global village, the population living on the earth is constantly increasing, and the consumption of resources is also increasing day by day. As the resource most closely related to human beings, water has also encountered unprecedented challenges. On the one hand, water is the source of life for human survival. On the other hand, with the continuous acceleration of human industrialization on the earth, various demands for water resources continue to growth; at the same time, it also brings endless pollution to natural water bodies in nature. [0003] my country is a large developing country with a population of 1.3 billion, but our per capita water resou...
