english 1. Abnormal Bubble Generation and Repair
- Manifestation: Decrease in the number of bubbles or uneven bubble size
- Common Causes: Clogged or worn cavitation generator, unstable pressure
- Repair Steps: Disassemble and clean internal impurities and scale; repair worn nozzles or Venturi tubes; check pipe seals; adjust pump pressure to a reasonable range
- Goal: Ensure stable cavitation and bubble generation
2. Poor Scum Separation and Repair
- Manifestation: Scum failure to collect or sink effectively
- Common Causes: Malfunction in scraper equipment, turbulent water flow, abnormality in diversion structure
- Repair Steps: Inspect scraper's transmission components; replace worn chains or motors; adjust scraping speed and frequency; repair deformed guide plates; adjust water flow distribution
- Goal: Extend scum retention time and ensure a stable scum layer
3. Abnormal Equipment Operation and Repair
- Manifestation: Unusual vibration or noise during operation
- Common Causes: Loose components, excessive friction, foreign objects blocking rotating components
- Repair Steps: Check tightness of all connections; re-secure loose pipes or brackets; lubricate rotating parts; replace worn bearings; clean foreign objects from impeller
- Goal: Prevent further damage and resume normal operation
4. Chemical Dosing System Failure and Repair
- Manifestation: Poor chemical delivery or abnormal dosage
- Common Causes: Clogged pipe or metering pump, deteriorating pump seals
- Repair Steps: Clear crystals or precipitates in chemical piping; replace clogged nozzles; check metering pump's flow control device; calibrate dosage accuracy; repair or replace pump seals
- Goal: Ensure stable dosage of the prescribed amount
5. Deteriorating Water Quality and Repair
- Manifestation: Increased effluent contaminant levels
- Common Causes: Pretreatment failure, degraded performance of core components, chemical incompatibility
- Repair Steps: Strengthen pretreatment filtration; clean impurities from screens and filters; check bubble generation quality; replace key components if necessary; reassess chemical compatibility; adjust dosage plan
- Goal: Restore equipment treatment efficiency
