How to achieveZero discharge of desulfurization wastewater?Let’s take a look together. Zero-discharge equipment for desulfurization wastewater is divided into acquisition and zero-discharge equipment according to emission standards. The wastewater treatment process is divided into general treatment process for desulfurization wastewater and zero-discharge treatment process for desulfurization wastewater.
Zero-discharge equipment for desulfurization wastewater: Conventionally treated water is mixed with EDR concentration, fresh water separation, fresh water flow into the regulating ground and circulation system drainage, domestic water, pre-treated industrial wastewater, initial rainwater, etc., used for AO biochemical biological denitrification, biologically treated water "UF RO" water reuse process, RO fresh water is used in the water inlet section of the boiler feed water treatment system, RO concentrated water is returned to the EDR water inlet, and the EDR concentrated water enters the evaporation and salt precipitation equipment.
Zero discharge of desulfurization wastewaterThe key technology lies in the method of removing high salt content in wastewater.
The desulfurization wastewater from coal-fired power plants has the characteristics of high salt content, complex composition, strong corrosiveness, and difficulty in reuse, which has become the key to limiting the zero discharge of wastewater from coal-fired power plants. At present, desulfurization wastewater generally uses the "coagulation precipitation pretreatment advanced treatment" process to remove soluble solids in the desulfurization wastewater in the form of crystallized salts. The treated water meets the requirements of the "Design Code for Industrial Circulating Cooling Water Treatment" (GB 50050-2007) and "Water Quality Index of Intermediate Cooling System Circulating Cooling Water" and can be used to supplement circulating cooling water in power plants.
chooseZero discharge of desulfurization wastewaterWhat are the issues that need to be considered? Let’s take a look at it together.
Judging from the current situation, our survival is seriously affected by wastewater, which seriously deteriorates our living environment. In order to control water resources from being polluted or reduce pollution, not only our daily emission reduction is required, but major industries also need to strictly control wastewater discharge issues. If zero discharge of desulfurization wastewater is very important at this time, what issues need to be considered when choosing zero discharge of desulfurization wastewater?
1. According to the requirements of incoming water, water quality characteristics, and emission discharge specifications, ensure zero discharge of desulfurization wastewater with simple process operation, small maintenance workload, and affordable price, so that the water meets the specifications.
2. In view of the water quality, quantity, characteristics and treatment requirements of the wastewater being treated, we strive to save investment and reduce operating costs in order to achieve advanced treatment technology, floor space, and strong applicability.
3. When using zero discharge of desulfurization wastewater, environmental issues should be fully considered, the impact on the surrounding environment should be minimized, noise, odor and solid waste should be reasonably handled to prevent secondary pollution.
4. When users choose zero discharge of desulfurization wastewater, they should fully consider the requirements for stable operation of the wastewater treatment system under adverse factors such as low temperatures in winter, and take timely anti-freezing measures for the equipment in winter.
There are so many introductions, but it is necessary to remind everyone that when choosing zero discharge of desulfurization wastewater, in addition to selecting zero discharge of desulfurization wastewater with high usefulness, efficiency, robustness, stability and automation, you must also consider the external factors of the equipment.
