For the first time in Yangzhou, the sewage treatment plant of the agreement was "drinking" to Qingdao Beer

"Thanks to the Guangling Ecological and Environment Bureau, this time I can" hold hands "with the sewage treatment plant, thanks to their help!" The relevant person in charge of Qingdao Beer (Yangzhou) Co., Ltd. sighed. A few days ago, Qingdao Brewery (Yangzhou) Co., Ltd. and Yangzhou Jieyuan Drainage Co., Ltd. (Tangwang Sewage Treatment Plant) agreed to indirect emission restrictions in cooperation agreements, and have formulated corresponding implementation clauses -this is the first time that Yangzhou has achieved sewage.

"For sewage treatment plants, 'carbon source' is very important." According to the staff of Qingdao Beer (Yangzhou) Co., Ltd., the relevant staff of Qingdao Beer (Yangzhou) Co., Ltd. mainly rely on microorganisms to "eat" pollutants during the sewage treatment process to achieve the goal of purifying water quality.

In order to maintain the activity of microorganisms and ensure the effect of nitrogen removal and phosphorus, the sewage treatment plant needs to purchase organic matter as a "carbon source", which increases the operating cost of the sewage treatment plant. As a high -concentration organic wastewater with good biochemistry, beer production wastewater does not contain toxic and harmful substances, which is a high -quality "carbon source". "At the same time as the" carbon source "in our wastewater, there are also high concentrations of nitrogen, phosphorus, suspension, etc. In order to ensure that beer production meets the emission standards, a lot of funds are invested every year." The staff introduced.

On one side is that the sewage treatment requires additional "carbon source", but on the other side, while having high -quality "carbon sources", it costs a large price to treat pollution. How to make the two take their own needs and effectively? Taking the "carbon source" as the fit point, the combination of beer production and sewage treatment -the recycling of beer production wastewater to create a new template for the circular economy is imperative.

At the end of 2020, the Ministry of Ecology and Environment and the State Administration of Market Supervision and Administration jointly issued the "Standards for Discharge of Pollutants for Beer Industry" (GB19821-2005) modification form, allowing beer manufacturing companies to sign an agreement with downstream sewage treatment plants to jointly agreed to water pollutant emissions emissions The concentration limit is no longer restricted by the pollution standards of the NATO.

The implementation of the modification form is a specific signal that adheres to the scientific pollution control and helps the development of the enterprise. The Guangling Ecological and Environment Bureau of Yangzhou City moved and became a "matchmaker" to actively lead the enterprise. They took the initiative to contact Yangzhou Jieyuan Drainage Co., Ltd., and analyzed and answered the difficulties and card points of Qingdao Beer (Yangzhou) Co., Ltd. to change the indirect emission limit. Enterprise relieving "acceleration".
