Black stinking water governance progress has just been announced, the national governance completion rate of about 44.14%, very few rivers did not start governance. E20 Research Institute of Industrial Research, head of well Yuanyuan said before and after comparison of data shows that the deadline for the exam is approaching, black foul water governance is in a state of rapid progress. At the same time, the penetration rate of the PPP model is still relatively low. The engineering state-owned enterprises, garden companies and traditional water enterprises have entered the state of "hegemony". Although the black foul water treatment is closely linked with the promotion of PPP mode, according to the research of E20 Institute, so far, the dominant mode of black foul water governance is EPC mode, accounting for 76.4% of EPC mode PPP model only accounted for 23.6%. "E20 Institute of Industrial Research, head of well Yuanyuan said. The following is a live text record (based on shorthand finishing): Regional characteristics show that China's black stinking water body governance rate of 44.14% In the water ten, driven by a series of PPP policies, China's urban water environment governance market is fiery. According to the national urban black-odor water remediation information release platform, as of August 16, 2017, China's smelly water body to control the river is 2100, to complete the management of 927, completed the treatment of 44.14%, less than half of the governance Accounting for 40.14%, very few rivers did not start the black-odor water treatment. It is reported that today March, the information platform released data show that the proportion of completion of governance is still 35% in August increased to 44.14%, also confirms the exam deadline approaching, China's black-odor water governance is in a state of rapid progress. In terms of specific provinces, the treatment of black-odor water bodies in our country shows a regional characteristic (the following icons are red, green, magenta and yellow areas) (1) Provinces in the red area have a governance completion rate below 50% at present, and the green area is above 50%. (2) Completion rate of the crimson region is less than 10%, which is distributed in Jilin Province and Hainan Province. At present, the hot Haikou is located in Hainan Province. (3) The middle of the yellow area is very conspicuous, is not activated at all, mainly in Ningxia. PPP project landed rate is low, black foul water governance EPC mode dominated Although the black foul water governance hot with the promotion of PPP mode complement each other. However, according to the research by E20 Research Institute, so far, the dominant mode of governance of black-odor water bodies is dominated by EPC mode, accounting for 76.4% of the EPC mode, while the PPP mode accounts for only 23.6%. In the 23.6% black-odor water PPP project, its floor rate is only 22%. During the investigation, we also found the interesting phenomenon of "scissors difference", that is, the budget is inversely proportional to the number of PPP applications. That is to say, the regions with a large number of PPP applications have weaker financial conditions, which reflects the fact that many regions PPP mode of "misreading" mistakenly consider the PPP model as a financing tool, and the focus is not based on the effect of governance, focusing on performance appraisal. Black-odor water treatment technology map released Before the technical map is released, it needs to be clarified that the treatment of black-smelly water is a systematic project. It should be cut from the "overall planning" and comprehensively planned. It is not a "headache" that depends on a certain point , Or a module can complete the project. However, the technical map from the technical point of view of enterprises, mainly for the management of technology to sort out. Engineering central enterprises, garden companies and traditional water companies tripartite "hegemony" Due to the landing rate of PPP projects, it is directly related to the undertaking of water environment governance nowadays. After some detailed communication and research, the E20 Institute mapped the technical map of black-odor water treatment, which clearly shows the corporate layout of black-odor water treatment. The entire black-odor water governance chain, mainly for the overall planning of the government regional environment, pollution control sources, water purification and ecological restoration, landscape restoration, internal governance and other five modules. The survey found that the current investors in water environment management, or PPP undertaking party, the main three major categories of enterprises are doing, the Central Enterprise Engineering Company, Landscape Garden Company and the traditional water companies three parties hegemony situation, and the three parties have their own advantages and disadvantages. First of all, the state-owned engineering company cross-border investment in water environment governance PPP, such enterprises have strong capital properties, rapid financing ability is strong, but the technology is weak, especially relative to the traditional water companies, such as Shanghai Urban Water Service, For example, Beijiao Water, Capital First, China Water Environment Group and other enterprises, the system integration capability is relatively weak, but it does not exclude some large central enterprises, such as Gezhouba Group, SU Jiake and other mergers and acquisitions through the acquisition of ways to strengthen environmental protection, environmental protection Operating company transfer. To talk about, starting with the landscape architecture, and gradually extended to the integrated management of water environment, enterprises. Typical representatives of the Oriental Garden and Tiehan ecology. These enterprises to undertake our comprehensive management of water environment project, the housekeeping skills in landscape architecture design, landscape remediation is also indiscriminate treatment of black and smelly water content, and in the current water and environmental projects account for a large proportion of In addition, such projects The company through the introduction of the team, mergers and acquisitions, etc., increase the quality of water in the module such as competition. Control pollution interception, mainly to control non-point source pollution and point source pollution. The survey found that if the source pollution interception, black and smelly water governance problems will be much easier. There are two types of point sources of pollution, industrial wastewater and domestic wastewater treatment. Point source control also emerged a number of technical know-how, in the field of subdivision has a skill of small and medium-sized environmental protection enterprises. In addition, a number of outstanding enterprises have also emerged in areas such as sewage outfall interception and pipe network. Endogenous governance, mainly including two aspects, one is dredging dredging, and the other is the sediment in situ repair. Water purification and ecological restoration is the most competitive enterprise in the field of water environment governance module. Through a single technology or a combination of technologies to complete the treatment of black and smelly water, and ecological restoration is the direction of most enterprises layout. Involving technical areas include water cycle, emergency treatment, ecological purification, microbial agents and shore zone repair. ID starch pump is a horizontal, single-stage, cantilever Centrifugal Pump. Its rated performance characteristics and installation dimensions conform to the standard ISO2858, and its manufacturing technical conditions conform to ISO5199. This series of pumps absorbs the advantages of KSB pumps and WARMAN pumps. The improvement of the pump makes the solid content of the conveyed liquid up to about 50%. It is specially designed for the transportation of special media with high solid content, precipitation and easy crystallization, and fiber in the starch, sugar, food, pharmaceutical, chemical and other industries. Put an end to "running", "running", "leakage", "blocking" and other phenomena, China Starch Association "starch equipment localized first-class product". Special Pump For Starch,Food Pump,Screw Pump,Food Transfer Pump Jiangsu Qiantu Trading Co., Ltd. , https://www.qiantupump.com
The impeller design of the ID series pump is based on the solid content of the conveying slurry, whether it is crystallized and glued, the size of the solid particle size, and the length of the suspended fibers. The impeller can be designed to be closed and the flow channel is widened on the premise of not affecting the rated performance. , semi-open, open, swirling, etc., the seal can be designed as single-end or double-end mechanical seal, with impeller plus packing seal, plus impeller plus skeleton oil seal, etc.
