Tiandi Environmental Protection Company closely follows the Group's “four industry” development strategy and relies on the membrane aeration biofilm reactor technology to undertake the MABR technology on the rural sewage station. Application Research and Demonstration and the International R&D Science and Technology Project of “Application and Demonstration of MABR Technology in Domestic River Wastewater Treatment” aims to expand the transformation of Tiandi Company and even the Group by taking the two businesses of rural sewage treatment and urban river management as the starting point. New development ideas at the stage.

MABR technology - advanced bubble-free aeration membrane treatment process

“MABR, the Membrane Aerated Biofilm Reactor, is a bioreactor based on bubble-free aeration on the membrane surface.”

Tiandi Company's technology project team introduced that MABR has many advantages, mainly in six aspects. First, no bubble aeration, high oxygen transmission efficiency, energy saving 90% compared to the conventional aeration method, operating costs will be reduced by 50%. Second, compared with the traditional activated sludge process, the sludge volume is reduced by about 50%, reducing sludge treatment costs. The third is modular size, can be spliced on demand, easy to install on site, and the overall footprint is small. Fourth, the degree of automation is high, the mobile APP is remotely monitored, and the site is unattended. Fifth, the membrane has a long service life and low maintenance cost. Sixth, the environment is highly friendly. Quiet operation, no foul smell, suitable for decentralized treatment.

Take the initiative and quickly grasp the MABR technology

In order to quickly and comprehensively absorb and absorb MABR's new technology, under the guidance of the company's leaders, Tiandi Company set up a special water treatment team to develop MABR technology, and invited technology many times. Manufacturers come to the company for training exchanges.

In order to gain a deeper understanding of MABR technology, Tiandi Company organized personnel to rush to the manufacturing base and conducted in-depth discussions and studies on related issues.

Tiandi Company has visited Changzhou, Hefei, Shanghai and other places to inspect other rural sewage treatment projects, and analyzed and compared the advantages and disadvantages of MABR technology, engineering costs and operating costs to ensure the company's technical reliability in MABR technology selection.

Tiandi Company has successively carried out engineering application research on rural sewage treatment and river water treatment direction.

In terms of rural sewage treatment, Tiandi Company has successfully built a demonstration project to treat terminal rural sewage with MABR technology in Outang Village, Gaojia Town, Qujiang District, Zhangzhou City, with a processing capacity of 40 tons/day. The system was successfully put into operation in March 2018. The results of the sampling test of the inflow and outflow by the third-party testing unit indicate that the water output index of the MABR rural sewage treatment terminal fully meets the Grade A standard of the Municipal Wastewater Treatment Plant Pollutant Discharge Standard GB18918-2012, which is at the domestic leading level in the rural sewage treatment terminal industry. .

“One of the highlights of this project is that compared with other rural sewage treatment processes, the project adopts a convenient management operation mode, and the mobile APP can timely upload water quality conditions and adjust operating parameters without personnel being on duty. The effluent water quality is stable and up to standard. It can operate safely and reliably for a long time, which perfectly fits the modernization requirements of China's industrial intelligence," the project team said.

In terms of river water upgrading, Tiandi Company has undertaken the international cooperation project of “Application and Demonstration of MABR Technology in Domestic River Wastewater Treatment” relying on the bilateral cooperation R&D platform of Zhejiang Science and Technology Department. It is carrying out river channel demonstration in Yuhuan County, Zhejiang Province. Applied research.

The demonstration river channel is the upstream branch river of the provincial control section of the reef head gate of Yuhuan City. It belongs to the key river monitoring section, and the online upload of water quality data is monitored every day. The implementation of the river water treatment technology has also been strongly supported and affirmed by the local government. They have said at the technical coordination meeting that they can help the “deterioration” of the river in Yuhuan County by virtue of the advanced river water upgrading technology. It is more conducive to the "deterioration" of rivers in Zhejiang Province and even the whole country.

The pilot test equipment of the project close to 7 months is stable, the water discharge effect is fully expected, and the effluent water quality fully meets the Class IV water body standard in the Surface Water Environmental Quality Standard. At that time, the river water body will be clear and will not produce any bad smell, which plays an important role in improving the living environment of the surrounding residents.

The prospects are ambiguous - grasping the big opportunities for market development

In the field of rural sewage treatment market, there are more than 600,000 administrative villages and more than 2.5 million natural villages in China. The domestic sewage generated in the following year is about 20-30 billion tons. Up to now, less than 20% of domestic sewage has been treated. The problems that have been dealt with are that the processing facilities cannot be operated in a long-term, the management is cumbersome, and the quality of the water is not up to standard. In the future, how to solve such problems in the long term will become the key to the emergence of rural sewage treatment technology.

In the field of river sewage treatment market, according to the results of the first round of black odor water survey in the country, as of February 18, 2016, among 295 county-level and above cities, 218 cities have black and odorous water bodies, of which 85.7% are rivers. With a total length of 5,596 kilometers, the country's black and odorous water remediation has a market scale of hundreds of billions. On June 14, 2018, the Zhejiang Provincial Government held a mobilization meeting for the construction of the province's large gardens, proposing comprehensive management and dredging of nearly 100 rivers across the province, with a total length of 2,725 kilometers and a total investment of 50 billion yuan. The construction period is 2016-2022.

In the face of such a huge market prospect, Tiandi Company has signed a bilateral strategic cooperation agreement on MABR technology. At the same time, through the optimization and integration of Dongfa Company, the talent echelon of the new water market was established, and the inherent advantages were established from the aspects of project management and operation and maintenance, and sufficient preparations were made for the promotion and application of MABR technology.

Only innovation can make life endless. MABR technology is of great significance for improving the industrial layout of Tiandi Company's water treatment sector, expanding the scale of the industry, increasing new profit points, and promoting the company's sustainable development strategy. In the future, Tiandi Company will continue to reform and innovate under the guidance of the scientific research of General Secretary Xi Jinping, “Green Water Qingshan is Jinshan Yinshan”, under the guidance of the development path of the Group's “Four Industries”, and seek greater development of the company.
