1. Experimental purpose:

The textile printing industry plays an important role in improving and enriching the people's material and cultural life. The pollutants in the textile printing and dyeing industrial wastewater are m--nly dirt, salt, oil and lipids on textile fibers such as cotton and h--r, as well as various pulp, dyes, surface active agents, auxiliary agents, acids, acids, acids, acids, and acids. , Alkali, etc., the large amount of wastewater in the textile printing and dyeing industry is one of the serious sources of pollution.

In order to understand the unit operation technology commonly used in textile printing and dyeing wastewater, master the processing process composed of these units, observe the actions of wastewater, sludge and --r during the treatment process, and specially produced small dynamic teaching experimental devices to improve people's understanding.

1. Experimental purpose:

Anaerobic digestion can be used to deal with organic sludge and high -concentration of dissolved organic industrial sewage (such as alcohol factories, food processing plants sewage), which is one of the m--n methods for sewage and sludge treatment.

In the process of anaerobic and digestion, it is affected by factors such as pH, alkali, temperature, and load rate. The amount of gas production is related to the types of operating conditions and types of pollution. Before the design of the digestive pool, it is generally necessary to determine the design parameters through laboratory trials. Therefore, it is important to master anaerobic digestive experiments.

Through the hope of this experiment, the following goals are achieved:

1 mastering anaerobic and digestive experiments;
