After Printing And Dyeing Wastewater Treatment, Still Drinkable.

As far as the printing and dyeing enterprises in Shaoxing are concerned, Han Xindi's "personal statement" really surprised them.

2 months ago, Han Xindi, a senior engineer of Zhejiang Kimberley Environmental Technology Co., Ltd., faced with a number of media in the local area, scooped up a bowl of treated dyeing wastewater from the sewage treatment pond and sent it directly to his mouth.

This kind of "cry out" that the factory considers to achieve zero pollution discharge and direct drinking behavior shows pure water quality. The active promoter behind it is a technology called deep well aeration process.

Xie Jiahai, general manager of Zhejiang Kimberley Environmental Technology Co., Ltd. explains that industrial waste water is not allowed to drink directly, but through the design of the deep well aeration wastewater treatment plant, the water quality can meet the two level emission standards of the state, especially can effectively reduce COD emissions.

According to the insiders, the characteristics of deep well aeration are mainly reflected in deep wells. Usually deep wells are between 50 meters and 150 meters. Due to the high circulation speed and high turbulence level in the well, the mass pfer between organisms and organic matters can be effectively carried out, so that the load can exceed the limit of conventional aeration, and the removal rate of organic matter can reach more than 90%.

Han Xindi said that through deep well aeration treatment equipment, printing and dyeing wastewater will eventually become "clean water". After filtration, the impurity will become a piece of "waste cake". It will not produce sludge, no sediment and odor, and has no impact on the surrounding environment. It can also be used as brick making and other environmental protection industries.

Just as many printing and dyeing enterprises in Shaoxing are not timing the new technology that will eventually come out of "clean water" and "waste cake", a printing and dyeing enterprise in Changzhou has pioneered the application of Kimberley's deep well aeration technology in wastewater treatment, and has been supported by a series of policies such as local government's subsidy fund.

These "abnormal phenomena" called "the fragrance of flowers outside the walls" by the local media in Shaoxing have touched the local dyeing and printing enterprises in Shaoxing greatly, or even surprised the Shaoxing Environmental Protection Bureau to lead the team to Changzhou to "learn from it".

Xie said that the cost of processing one ton of waste water is about 1000 yuan, and 7 million of the investment will take 3 years to recover the cost.

According to the insiders, if the waste water treatment plant is used, the investment will be large in the early stage. Now it does increase the burden on the enterprises, but in the long run it is a long-term guarantee for the development of the enterprises.

At present, this new sewage treatment technology has attracted the attention of many enterprises in Hangzhou Bay area, such as Jiaxing and Haining, in textile, pharmaceutical and other industries. Xie revealed that many business executives directly came to their company to discuss relevant cooperation matters.
