It was learned from the Stainless Steel Industrial Park on June 21 that after years of intense construction, the first phase of the new sewage treatment plant in the park has been completed and entered the trial operation and commissioning stage. The production in the park and the domestic sewage of the nearby people have all achieved harmless treatment. The ecological environment of nearby rivers has also been improved accordingly.
Say goodbye to disorderly emissions
Previously, due to the absence of a sewage treatment plant in the park, most of the wastewater produced by the enterprises in the park was treated in a remote sewage treatment plant, and the domestic sewage of the surrounding residents was discharged into the Xiaohui River. In order to meet the economic development of the park and the expansion of the planned area, and to ensure that the domestic sewage of nearby residents will no longer be discharged into the river, our city plans to build a sewage treatment plant in the stainless steel park.
The sewage treatment plant started construction in 2016 and is located in the north of the stainless steel industrial park, on the south bank of the Yangxing River channel, covering an area of about 33 acres. In order to speed up the construction of the sewage treatment plant, the park management committee organized related departments such as investment promotion, land, planning, construction, environmental protection, and the municipal planning institute to learn advanced experience in other places. The construction scale of the first phase of the project is 10,000 tons of sewage per day. It will increase to 28,000 tons of sewage per day. At the end of 2018, the construction of the sewage treatment plant was basically completed and is currently in the trial operation and commissioning stage.
Advanced processing technology
Because the sewage treatment plant adopts a new technology, the treated sewage adsorbs heavy metal ions that are harmful to microorganisms, refractory organics and other substances, and it has the conditions for recycling and reuse. Therefore, in addition to improving the local water environment, the treated reclaimed water can be reused in the industrial park for recycling and reuse.
The core technology adopted by the sewage treatment plant is diatomaceous earth sewage treatment technology, which is a domestic leading scientific and technological achievement and has twelve patented technologies. This technology is a new technology that is implanted in any traditional sewage process and undergoes qualitative changes. It can treat sewage to discharge standards through physical and biological synergy. Compared with traditional sewage treatment technology, it is more energy-efficient, more efficient, and can realize the recycling and reuse of water resources.
Moreover, the technology has high treatment efficiency, and its biochemical residence time is about 30% less than that of the traditional process; the effluent effect is good, the treated reclaimed water is clear and transparent, and there is no peculiar smell; the sewage treatment plant constructed by this technology does not have any odor or odor. It is necessary to add deodorizing equipment to eliminate the odor in the plant area; the amount of sludge produced is still small, and the remaining sludge will not cause secondary pollution.
Expansion of collection
After the sewage treatment plant is completed and put into use, in addition to the daily sewage generated by the production enterprises in the park, the domestic sewage of nearby residents will also be included in the collection scope.
Simultaneously with the construction of the sewage treatment plant, there is also the laying of sewage pipelines. In order to expand the scope of collection, construction workers laid sewage pipelines to nearby urban villages or residential communities. According to the city’s black and smelly water treatment plan, the sewage from Xiaohuihe River has also been intercepted and sent to the sewage plant for treatment, and the Yangxing River sewage interception pipe project is still being implemented.
The relevant person in charge of the stainless steel industrial park said that the commissioning of the sewage treatment plant has greatly eased the pressure of sewage treatment around the area, effectively treated black and odorous water bodies, and improved the water environment around the industrial park. In the future, the park will attract investment and grow stronger. , The introduction of advanced production technology and the construction of environmentally friendly and green industrial parks play an important role in promoting.
