Abstract

The invention discloses a system and a method for cultivating anaerobic activated sludge by using vermiculite. The invention belongs to the field of waste treatment and aims to improve the prior art in the aspects of cost and product properties. By a method for adding liquid dung and wheat straw powder into a fermenting pool, the cost is reduced and the properties of the activated sludge are improved.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to an activated sludge production equipment and production method. Background technique [0002] Activated sludge is a general term for microbial groups and the organic and inorganic substances they attach to, and can be divided into aerobic activated sludge and anaerobic granular activated sludge. Activated sludge is mainly used to treat sewage and wastewater. Activated sludge method is a kind of aerobic treatment method that uses suspended microbial flocs to treat organic sewage. [0003] The existing activated sludge production method is to add certain nutrients to the activated sludge. According to the existing production equipment and production methods, the activated sludge produced by it has poor performance and high cost. Contents of the invention [0004] The object of the present invention is to provide a system and method for cultivating anaerobic activated sludge w...
