固定化细胞处理废水的关键性包埋技术条件研究

研究了以聚乙烯醇为主要包埋材料的混合载体，固定化细胞处理有机废水的关键性包埋技术条件，解决了妨碍固定化细胞在废水处理领域推广应用所的制备成球难，活性丧失大、易破碎、发胀粘连上浮等问题。

STUDY ON THE KEY CONDITION FOR ENTRAPPING CELLS APPLIED TO WASTEWATER TREATMENT

The key conditions under which cell was immobilized with a mixedcarried process using poyvintl alcohol (PVA) as major entrapping material werestudied. It was found that the mixed carrier process effectively solved th e probl-ems that the immobilized cell technology applied in wastewater treatment faced,such as difficulty in forming spherical particles,ease of the particles to be bro-ken, loss of the activity in producing methane and floatation of the particles uponproducing methane.
