6.4.2 .2 Waste residue and waste water disposal procedures

If it is a failure of sewage treatment station equipment, emergency repair should be carried out according to its severity. If it cannot be repaired immediately, it is easy to cause waste water and waste accumulation. The disposal procedure is shown in Figure 5-2.

6.4.3 Happy Accident Handling

6.4.3 .1 Risk analysis

Xinxiang environmental risk accidents mainly include ammonia leakage caused by failure of ammonia absorption system and ammonia leakage caused by improper storage of ammonia, which can cause pollution to the atmosphere and wastewater, and may also bring risks such as letters and visits and complaints to the company.

6.4.3 .2 Disposal procedures

If the ammonia three-stage absorption system malfunctions and a large amount of ammonia is discharged to the atmosphere, production should be stopped immediately, and the reactor being produced should be gradually cooled to gradually stop the reaction. At the same time immediately notify the relevant departments to launch emergency plans to repair damaged equipment as soon as possible.

Ammonia is a toxic gas and inhalation in large quantities can strongly irritate the nose, throat and lungs. Symptoms may include a burning sensation, cough, worsening wheezing, shortness of breath, headache, and nausea. Overexposure affects the central nervous system and can cause spasms and unconsciousness. The upper respiratory tract is vulnerable and causes bronchitis (closed airways). The vocal cords are particularly susceptible to corrosion at high concentrations, and lower respiratory tract injuries can cause edema and bleeding. Five minutes of exposure to 5000 ppm can cause death. If the ammonia concentration in the effluent is high (you can judge it empirically based on whether the smell on the site is pungent), you should immediately organize an orderly evacuation of employees in the plant area. The specific disposal procedures are shown in Figure 5-3.
