From August 6 to 8, 2022, the 2021-2022 China Environmental Sanitation Expo will be held in Xiamen. The expo will showcase comprehensive solutions in the field of environmental sanitation, and help further promote the high-quality development of China's environmental sanitation industry. As the flagship enterprise of the smart environmental protection sector of Hanwei Technology Group, Jiayuan Environmental Protection has been deeply engaged in smart environmental solutions for many years, and is also invited to participate in this grand meeting.
In the field of urban sanitation, in addition to the treatment of solid waste, waste water and waste gas treatment is also two complex systems engineering. In the past is usually the waste water, waste gas respectively to different service providers to deal with, this is not only cumbersome, high treatment costs, and covers a large area, at the same time in the process of treatment is easy to produce odor caused by secondary pollution, and low degree of automation, many links must have staff participation in order to carry out.
Jiayuan Environmental Protection combined its own years of environmental treatment technology accumulation, combined with Hanwei Technology Group's advantages in sensors, smart terminals and other aspects, to create the transfer station water vapor combined treatment + information scene solution, through intelligent environmental means to solve the problem of wastewater and waste gas treatment. The scheme is divided into small and medium transfer stations depending on the scale of processing.
The small transfer station adopts the main treatment process of "pretreatment + physicochemical +MBR" to collect and treat the pressure filtrate, vehicle flushing water, domestic sewage and other waste water. The water quality after treatment can meet the "Water Quality Standard for Sewage Discharge into Urban sewers", and can be directly discharged into the municipal sewage network. For the discharge and compression workshop, sewage treatment station, road passage, workshop and wall generated odor, the use of negative pressure integrated equipment deodorization method, plant liquid spray tower deodorization method and spray deodorization method after treatment to reach the discharge standard. Small transfer station environmental treatment scheme covers a small area, due to the short construction period, so the project start speed is fast. At the same time, the whole system has a high degree of automation, and because of the independent plug-in layout, not only the failure rate is low, but also the later maintenance cost is relatively low.
Different from small transfer stations, large and medium-sized transfer stations adopt the sewage treatment process of "pretreatment +A2O+MBR+ intensive coagulation". Sewage and odor treatment schemes of refuse transfer stations can be customized one to one according to needs, and different treatment processes can be adopted for different odor producing areas: For discharge and compression workshop, the use of negative pressure integrated equipment deodorization, sewage treatment station using plant liquid spray tower deodorization, traffic channels, workshops and walls are deodorized by spray. In this way, on the premise of ensuring the governance of the whole scene, the cost of the demand side is effectively reduced, and the governance efficiency is improved. At the same time, the integration of the information platform makes the whole management process more convenient. Large and medium-sized transfer station environmental governance program also has the characteristics of small area, low cost, because of the use of PLC full automatic control, so that the operation management of the entire equipment more convenient. Since its launch, the two water-gas combined transfer station programs have been applied in several environmental treatment projects of transfer stations across the country, and have been recognized by relevant sanitation departments, greatly improving the efficiency of water-gas treatment and reducing capital and labor costs at the same time.
As a technical engineering enterprise, Jiayuan Environmental Protection after more than 20 years of development, now has the environmental water, gas double A design qualification, design research institute and equipment production and manufacturing base. Up to now, it has the special Class A design qualification of environmental engineering (water pollution prevention and control engineering, air pollution prevention and control engineering), the professional Class B design qualification of municipal industry, the first class Operation service Certificate of live landfill leachate treatment facilities, the special qualification certificate of environmental pollution Prevention and Control Engineering, etc., which can be based on the needs of users, We provide whole-process environmental protection system solutions from system design, equipment purchase and sale, construction and installation to commissioning and operation services. We have established an intelligent environmental management system with "monitoring + detection + management + operation + service" as the core, realizing the capabilities of real-time monitoring, early warning and remote operation of facilities. < /p>At present, Jiayuan Environmental Protection has grown into a national environmental protection industry backbone enterprise, national high-tech enterprise, national intellectual property advantage enterprise. At the same time, it is also a provincial-level excellent innovative enterprise, a provincial-level backbone enterprise of strategic emerging industries and a provincial-level specialized and specialized new enterprise. On the first weekend of August, we welcome people from the environmental protection industry to visit our booth 3T67 in Xiamen International Convention and Exhibition Center to share their wisdom and experience.
