Cycle cycle activity sludge method tr--ning device,Schneider PLC comprehensive tr--ning device

1. Experimental purpose:

The cycle cycle activity sludge method (CYCLIC Activated Sludge System (CASS) is developed on the basis of the Iceas process. It is an improved type of SBR process. One cycle is composed of the following stages: filling water / aeration, filling / precipitation, skimming, idle. This process is a circular intermittent sewage treatment process with a nitrogen -dehydration and phosphorus removal effect. It has the advantages of traditional SBR treatment technology. At the same time, it can effectively inhibit the expansion of silk -like bacteria. Teaching demonstration and dynamic experimental equipment for process. Through the hope of this experiment, the following goals are achieved:

Through this experiment, I hope to achieve the following goals:

1. Understand the characteristics of the CASS method system;

2. Deepen the understanding of the CASS method and the operation process.

2. M--n technical indicators and parameters:

1. Environmental temperature: 5 ℃ ～ 40 ℃

2. Treatment of water: 3 ～ 8L/h (average)

3. CASS: Stay time: 4, 6 ～ 14h

4. Second Shen Pond: Staying time: 4 ～ 1H

5. According to the local sewage data as the standard:

6. Design and water quality range:

Inlet water BOD5 400 ～ 800mg/L Out of water 50 ～ 100 mg/L

COD 600 ~ 1200mg/L out of water 100 ~ 150 mg/L

Entering SS 200 ～ 400mg/l Disture 30 ～ 40 mg/L

Inlet water pH 6-9 out of water 6-9
