Today, as environmental pressure becomes increasingly prominent, there are still a large number of sewage plants and corporate sewage stations that cannot achieve stable compliance due to reasons such as process design problems, water quality changes, operation management problems, and technical strength problems. In order to meet the standards, a large number of engineering companies have proposed solutions that are often to continuously add structures, add new equipment, and extend treatment processes. The resulting problems such as a large amount of investment, unknown effects, and site restrictions have placed heavy burdens on sewage plants or enterprises. Pressure, and judging from the current environmental protection situation, it will only become more and more severe. Therefore, it is of great practical significance to find a simple, fast, low-investment and low-cost way to solve the current difficulties of enterprises. Through technical means, the three major functions of charge neutrality, adsorption, and oxidation coagulation of the reagent have been strengthened, and the COD degradation ability of the reagent has been greatly improved. At present, many industrial wastewater and comprehensive sewage treatment plants in the park still fail to meet discharge standards after undergoing conventional treatment processes. The removal rate of ordinary chemicals has been extremely limited. The adoption of other treatment measures has large investment and high operating costs. The new reagent we developed strengthens the charge neutralization, adsorption, oxidation and coagulation functions of the reagent, and greatly improves the COD removal rate of the terminal wastewater. Most wastewater can be increased from about 20% of the removal rate of ordinary reagents to 50-70%. And the cost is low.
The product is simple to use and control, and there is no need to invest in new equipment. The standard can be easily raised by replacing the original drug, saving customers a lot of investment and transformation time. It can be widely used for upgrading comprehensive sewage plants and industrial sewage plants in the park
Case 1:
An industrial park in Zhejiang treats 30,000 tons of sewage per day. The storage water includes printing and dyeing mills, paper mills, chemical plants, and domestic sewage. After front-end treatment, the COD of the effluent from the biochemical secondary sedimentation tank fluctuates between 100 and 140mg/L for a long time, while the discharge standard of the factory is that the COD is lower than 50mg/L. The use of conventional pharmaceuticals can only reduce it to 70-90mg/L. In the factory's subsequent standard raising process, Fenton process was added at the end, and the standard raising cost was about 1.6 yuan/ton of water. After sampling and selection by our company, the factory will use a certain type of medicament of ours. After treatment, the COD can reach 35-45mg/L. Although it is slightly higher than that of Fenton effluent, the cost is only 0.7-1.0 yuan/ton of water, saving a lot of operating costs, and compared with Fenton, the labor intensity of workers is greatly reduced.
Case 2:
The comprehensive sewage volume of a sewage plant in a printing and dyeing industrial park is about 40,000 tons/day. After treatment, the COD of the sewage can only be reduced to 70-80mg/L, while the emission standard requirement is below 50mg/L. After using our new reagent C201, the COD can be reduced to a minimum of 24mg/L, which can basically be maintained between 35-40.
Case 3:
A sewage plant in a printing and dyeing park has pure printing and dyeing wastewater, with a comprehensive water volume of about 20,000 tons/day. Due to the long time it took to build the factory and problems in the process, the sewage can only be treated to about 150-180mg/L. A foreign imported reagent was used, and the minimum can only be reduced to about 80mg/L (the emission standard is 80mg/L). Our agent has been tested and can reduce COD to about 60mg/L at the same cost.
Case 4:
Coking wastewater from a steel enterprise. After the preliminary treatment, both COD and ammonia nitrogen failed to meet the standards. After using our chemicals, the discharge standards were achieved.
Case 5:
The sewage plant of a papermaking enterprise in Jiangsu has a water volume of about 15000 tons/day. The terminal wastewater was originally used with Fenton, and then the reagent provided by us was used. After calculation, the annual reagent cost was saved by about 1 million yuan, and the sludge volume was reduced by 1/3.
