What are the common problems in the water treatment industry? Sedum Environmental Technology believes that, in a nutshell, it is mainly these:
01 Problems with the market access system
my country's environmental protection industry started relatively late, so the management system of water treatment equipment is not sound.
It is not clear which department is responsible for the unified management of water treatment equipment manufacturing enterprises all over the country; while the industrial threshold is low, there are many small enterprises and small workshop-style enterprises, and there are a large number of leather bag companies that do not have standardized production conditions and production facilities. exist. The whole industry gives the impression that it is a mixed bag, and there are all kinds of companies.
02 There are problems in the quality supervision of water treatment equipment
The vast majority of water treatment equipment are non-standard customized products. Therefore, many manufacturers process the parts in the production site and then assemble them on site. In theory, the quality supervision department must be at the construction site to accurately judge whether the quality of the equipment is up to standard.
However, due to the division of departmental functions, the quality supervision department currently only supervises the quality of products on the market; the environmental protection department in each region only supervises the operation effect of the project. The problem here is that the quality supervision mechanism of environmental protection equipment has not yet been formed, and the quality supervision and management of water treatment equipment lacks a clear supervisory unit, which leads to the lack of management methods.
03 Slow development of standardization of water treatment equipment
There is no unified industry standard for water treatment equipment at present, but three kinds of industry standards are parallel. The Ministry of Environmental Protection, the Ministry of Housing and Urban Construction, and the machinery industry standards all involve water treatment equipment, but in terms of content, the standards are repeated and applied. There are disputes, the standard management is chaotic, and the standard management data lacks detailed and credible actual data support for the domestic water treatment situation, which brings about the problems that the standard itself is not standard enough and the reference value is not high.
04 Overall, my country's water treatment technology is still not advanced enough
The current sewage treatment rate is not high, the water treatment technology is backward, and there is a big gap in the overall utilization capacity of water resources.
Although in recent years, researchers have been able to design and manufacture water treatment equipment and corresponding processes suitable for resources and environments in different regions of my country by learning from foreign advanced water treatment equipment design and manufacturing technologies, after research, analysis, digestion and absorption. In terms of the overall technical level of the equipment, compared with the advanced level of developed countries, there is still a big gap.
These gaps are manifested in: insufficient rigor of technical standards, insufficient reliability and safety of equipment operation, insufficient durability, and obvious gaps in operating efficiency and energy consumption performance.
As for the high-tech special water treatment equipment and new general-purpose water treatment equipment, my country's current technology is far from reaching the international advanced level, and the technology is still in the initial stage of exploration.
05 There is a shortage of technical talents in water treatment
We know that sewage treatment is actually an adjustment and combination of four dimensions: residence time, treatment space, input energy, and material consumption. It can even be said that high-standard effluent quality is the transfer of pollution forms in the form of energy consumption and material consumption. to be realized.
In order to improve the efficiency of water treatment and change the energy consumption and material consumption in water treatment, more personnel related to water treatment technology are needed. However, in my country, water treatment technology lacks relevant professional settings and lacks systematic training.
How to ensure high-quality water while reducing energy and material consumption is a problem that requires long-term research and exploration.
06 Insufficient sewage treatment capacity, lagging behind in upgrading and renovation
The sewage treatment plants in many places have insufficient sewage treatment capacity and the equipment is in a state of overload operation.
When industrial sewage from some industrial parks is discharged into local rivers, the total nitrogen concentration exceeds the standard seriously; even in some local sewage plants, even the 1st grade A standard cannot be reached.
We will also notice that there are large gaps in the sewage pipe network in different regions, and there are many problems of domestic sewage overflow; in some places, the regional pipe network is not divided into rain and sewage, mixed and misconnected, and the problem of direct sewage discharge during flood season is serious.
