Ground type: rock wool insulation type, heat tracing constant temperature type, container type, all of which can be equipped with equipment rooms;

Underground type: often equipped with above ground equipment rooms, and can also be equipped with underground equipment rooms;

In the previous issue, we shared with you the issues of abnormal effluent quality and response strategies, questions 16-3. Today, we will share with you questions 31-58 after abnormal effluent. The content is as follows: Question 31: The process of the small sewage treatment plant we are working on is to lift the well grid well, adjust the tank, reaction tank, inclined plate sedimentation tank, hydrolysis acidification tank, MBR tank, and sludge tank. The lift well used has a lift pump, the adjustment tank has a blower and submersible sewage pump, the hydrolysis acidification tank has a submersible agitator, and the MBR tank has a blower and MBR effluent pump. May I ask if the blower should be turned on first when turning on the machine, and then turned off when turning off. Is there any other order? Also, the MBR discharge pump is the self-priming pump with a section of pipe on top. Originally, the water inside was clear, but now it has turned completely black. What's going on? Answer: The opening sequence is usually based on the process from front to back, and the system can generally withstand certain load changes. Therefore, opening in the order of front to back is sufficient. Even if there are mistakes, correcting the opening sequence in a timely manner is generally not a problem.

3. MBR membrane category: central control fiber membrane, flat membrane, columnar flat membrane

4. Appearance: reinforced type, corrugated/folded plate type, buckle plate type, container type

5. Main materials: anti-corrosion carbon steel, fiberglass, 304 stainless steel

Introduction to the functional areas of integrated sewage treatment equipment

1) Anaerobic reactor: The raw sewage and phosphorus containing reflux sludge discharged from the sedimentation tank enter the reactor synchronously, and its main function is to release phosphorus while ammonifying some organic matter;

There is no molecular oxygen or compound oxygen present in the anaerobic tank, and the electron acceptor for organic matter degradation is organic matter, DO<0.2 mg/L， Anaerobic reactions require high and stable temperatures, with medium temperature reactions ranging from 31 to 33 ℃ and requiring strict pH control.

2) Hypoxia reactor: Sewage enters the reactor through an anaerobic reactor, and its primary function is denitrification. Nitrate nitrogen is sent from the aerobic reactor through internal circulation, and the circulating mixed liquid volume is relatively large, generally 2Q (Q - original sewage volume);

Shandong Rongboyuan people firmly believe that quality wins respect and can reliably carry heavy loads!
