The waste generated by our production activities includes waste water, waste gas, solid waste and noise. SBS has continuously invested and optimized the waste treatment equipment, improved the production process and raw materials, and established an effective waste management system for a long time. We have a good reputation and demonstration of waste treatment and management ability in the local region.
The designed maximum treatment capacity of our waste water treatment station is 1400 tons/day.
After separate chemical treatment, class one pollutants in the waste water meet the standards. The recyclable waste water enters the reuse system for the second treatment after physical and chemical treatment. The reuse rate of waste water is 50% in total. After deep treatment, the recycled concentrated water reaches the discharge standard and is discharged. Our waste water treat-ment station is equipped with a complete online monitoring system with wastewater monitoring management standards, operation standards, emergency plans, abnormal operation standards and other supporting systems. According to SOP requirements, decontamination employees should pass the exam and get certificates after training. The sludge generated in the treatment process is stored and transported in compliance with the regulations.
Formulating standard operating procedures, we treat the waste gas strictly and assign specific employees to manage and monitor the bleaching waste gas online.
Through long-term equipment introduction and technical transformation, SBS has good control of equipment noise. With the help of regular monitoring, no factory boundary noise exceeds the standard.
At the same time, in order to prevention, we have formulated a detailed emergency plan for pollution and waste and conducted regular drills to continuously strengthen employees’ capacity, improve management ability and enrich management connotation.
Treatment of Electronplating Effluent
Waste Water Treatment Equipment&Facilities
Chemical (up to standard) Treatment System
A reasonable layout is helpful to the efficient and stable operation of waste water treatment.
Introduction: The waste water treatment control system senses the main process parame-ters of each reaction tank through PH and ORP meter heads. When waste water treatment control system is running, it automatically transfers the control information to the linkage dosing device according to the set parameter range, so as to realize automatic dosing, with manual timing inspection to ensure foolproof.
Case 3 :
1.Electroplating waste water is pumped to the chemical reaction tank through the lifting pump for treatment. The pollutants are transformed into settleable substances and flocculated into large particles.
2. The flocculated materials are precipitated in the sedimentation tank, while clean water enters the reuse system after secondary precipitation.
Introduction: Water after chemical treatment enters the reuse system. The treatment processes are as follows: sand filtration, carbon filtration, ultrafiltration, primary RO, secondary RO and the reuse of reclaimed water. The quality of recycled water is better than tap water and can be directly used in the electroplating workshop.
1.Sand filtration mainly filters particulate matter in water, while carbon filtration absorbs organic matter.
2.The pore size of ultrafiltration membrane is 0.05um–1nm and the operating pressure is 0.1-0.5mpa. It is mainly used to trap and remove macromolecular substances such as sus-pended substances, colloids, particles, bacteria and viruses in water.
Primary and Secondary RO Filtration
Reverse Osmosis is a film-separating technology which powered by osmotic pressure differ-ence. The pore size of RO reverse osmosis membrane is nanometer scale. Under certain pressure, water molecules can pass through the RO membrane, while inorganic salts, heavy metal ions, organic matter, colloids, bacteria, viruses and other impurities in the source water can’t, so that the pure water and the concentrated water can be distinguished. To ensure the stability of the reuse water, the secondary RO is used for filtration.
Online Monitoring System for Waste Water Treatment
1.SBS has an independent online monitoring room to keep constant temperature and humidity according to requirements. Besides, SBS selects the intelligent industrial control instruments and online testing equipment produced by enterprises which pass the certifica-tion of environmental protection department.
2.The online monitoring system is networked with the information center of the environmen-tal protection department, and the data is shared in real time through the network. The moni-toring equipment automatically conducts sampling tests every two hours and be calibrated according to environmental protection requirements per month.
The Discharge Outlet of Waste Water
1.After deep treatment, the recycled concentrated water reaches the discharge standard and is discharged.
2.The discharge outlet of waste water is provided with an online flow monitoring meter and relevant online pollutant monitoring sampling points.
Sludge Treatment Equipment & Facilities
1. The sludge produced by the sedimentation tank of the waste water treatment station is pressed and filtered by the press filter to become dry sludge.
2. The sludge is collected and placed in nickel, chromium and copper partition, and recorded in real time. The sludge storage warehouse has great rain – proof, anti – corrosion and anti – seepage performance.
Waste Gas Treatment Equipment & Facilities
Introduction: The picture shows the waste gas collector in our company. After entering the filler absorbing tower for purification treatment, the waste gas is defogged by the dewatering layer, meeting the standard emission, and is discharged through the exhaust cylinder.
