Tianjin Youfa Dezhong Steel Pipe Co., Ltd. -2019 Self-Monitoring Plan
Tianjin Youfa Dezhong Steel Pipe Co., Ltd.
Self-monitoring programme
（2019annual)
Description
According to the requirements of the Ministry of Environmental Protection's "Measures for Self-monitoring and Information Disclosure of National Key Monitoring Enterprises (Trial)" (Huanfa [2013] No. 81), Tianjin Youfa Dezhong Steel Pipe Co., Ltd. organizes self-monitoring of the pollutants discharged, Refer to the "General Provisions of Self-monitoring Technical Guidelines for Pollutant Discharge Units" (HJ819-2017) and relevant regulations to formulate the company's 2019 self-monitoring plan.

|
No. 1 Galvanizing Plant Second Galvanizing Plant |
Waste water: acid cleaning waste water, boiler drainage, cooling water drainage, waste gas treatment waste water and other production waste water are produced in the production process, and domestic sewage is produced in the life of workers. Exhaust gas: hydrochloric acid mist is produced in pickling tank, zinc smoke is produced in hot galvanizing process, and gas flue gas is produced in zinc pot heating furnace and steam boiler. Noise: Noise generated during the production process. Solid waste: hazardous waste such as waste acid, sludge, waste oil and domestic garbage are produced in the production process. |
||
|
Welded Pipe No. 1 Factory No.2 Welded Pipe Plant |
Wastewater: domestic sewage Exhaust gas: particulate matter produced during the welding process; heating boiler gas flue gas (No. 1 plant) Noise: Noise generated during the production process. Solid waste: hazardous waste such as waste engine oil and domestic waste are produced in the production process. |
||
|
Pollution treatment facilities construction, operation, and pollutant discharge destination |
|||
|
Wastewater: production wastewater is used“Neutralization+flocculation”Reuse after process treatment; take over Daqiuzhuang Town Sewage Treatment Plant after treatment with integrated equipment for domestic sewage (reuse after treatment of domestic sewage from welded pipe plant 1). Waste gas: produced in the pickling section, which is treated by alkali liquor absorption and then treated15mHigh exhaust pipe emissions; zinc fumes from the hot-dip galvanizing process are treated with a bag filter.15mHigh exhaust pipe emissions; low nitrogen burners for gas boilers, flue gas through18mHigh exhaust pipe emissions; flue gas from the gas of the zinc pot heating furnace.15mHigh exhaust vent. Noise: foundation vibration reduction and workshop wall sound insulation are adopted for noise pollution prevention and control. Solid waste: hazardous waste is entrusted to a qualified unit for disposal, while general industrial solid waste is recycled by the material department; domestic waste is cleaned and transported by sanitation. |

Note: ① If the detected content of pollutants in the soil of a specific plot exceeds the screening value, but is equal to or lower than the background value of the soil environment, it will not be included in the management of the contaminated plot.
5. Testing quality system
If other qualified inspection (supervision) testing institutions are entrusted to carry out self-monitoring on their behalf, the pollutant discharge unit does not need to establish a monitoring quality system, but the qualification of the inspection (supervision) testing institutions shall be confirmed.
6. Requirements for recording, sorting and archiving of monitoring data
1. The records of manual monitoring shall be implemented in accordance with the General Principles of Technical Guidelines for Self-monitoring of Sewage Discharge Units. Records of manual monitoring: the date, time, pollutant discharge port and monitoring point, monitoring method, monitoring frequency, monitoring instrument and model, sampling method, monitoring result, etc. of manual monitoring shall be recorded regularly, and a ledger record report shall be established.
2, monitoring data sorting and archiving design record form, the key information of the monitoring process to be recorded, sorted and archived, the record form is electronic and paper simultaneously recorded, the retention time is not less than three years.
