Exhaust gas and sewage treatment equipment system description
I. Intelligent collaborative system
Linked control logic: Exhaust gas treatment fan and spray line
start and stop linkage (delay ≤ 10 seconds)
Automatically start emergency neutralization program when sewage pH
value is abnormal
IoT monitoring: Cloud data platform (supports API connection to
Environmental Protection Bureau)
Real-time alarm: VOC exceeds standard, membrane pressure difference
> 0.1MPa, etc.
Energy-saving technology: RTO waste heat is used for MBR pool
insulation (energy saving rate ≥ 18%)
Photovoltaic drive auxiliary equipment (optional)
II. Selection comparison guide
Production scale | Recommended waste gas solution | Recommended sewage solution | Total investment range |
Small (<50,000 pieces/year) | Activated carbon adsorption + UV photooxidation | Physical and chemical treatment + chemical oxidation | 800,000 to 1.5 million yuan |
Medium (50,000-200,000 pieces/year) | RCO catalytic combustion | MBR + deep filtration | 2 million to 5 million yuan; |
Large (>200,000 pieces/year) | RTO + zeolite rotor concentration | Full process biochemical + zero emission system | 8 million to 20 million yuan |
III. Response to special working conditions
High-salt wastewater: Configure DTRO high-pressure reverse
osmosis module (desalination rate > 98%)
Paint residue-containing waste gas: Add dry paint mist filter
(self-cleaning type)
Extreme climate: Equipment cavity heating/cooling temperature
control system (applicable to -20℃~50℃)
Note: The above plan needs to be combined with the requirements of the environmental impact assessment report (new version of HJ 1012-2025 in 2025). It is recommended to reserve 15%~20% of the processing margin to cope with the capacity ramp-up.
