Different from China, developed countries abroad have long realized that sludge treatment and disposal is an indispensable link in the process of sewage treatment.

Different from China, developed countries abroad have long realized that sludge treatment and disposal is an indispensable link in the process of sewage treatment. They have made clear provisions on the objectives of sludge treatment and disposal in terms of laws and policies, and ensured the implementation through a series of policies.

In sludge treatment of the United States, in addition to the treatment of generated sludge, the whole sewage treatment system and sludge treatment system are regarded as an organic whole. In sewage treatment, sludge co-treatment is realized. As early as 1998, the European Union legislated to ban the Marine discharge of sludge, and the sanitary landfill of sludge should be gradually banned. The annual sludge capacity of 50,000 sewage treatment plants in EU countries is 40 million tons, and more than 50% of the sludge has been treated with anaerobic digestion, among which the anaerobic digestibility of sludge in Britain reaches 66%.

It can be seen that policy and technology are still effective ways to improve China’s sewage treatment capacity. Technical methods: to further accelerate the localization of sludge treatment and disposal equipment, improve the management and operation level of sewage treatment plants. In terms of policy, effectively coordinate the management of sludge treatment and disposal involving multiple units; More binding mandatory sludge discharge standards; Actively support the development and application of new sludge treatment technology; To encourage investment in sludge treatment by water plants. 66%.

The sewage treatment industry still has a lot of things to do.

Although the sewage treatment capacity, treatment capacity and treatment rate are all improving, it does not mean that the sewage treatment effect is improving simultaneously. Therefore, under the big theme of improving the quality and efficiency of sewage today, the sewage treatment industry still has a lot of things to do.

In addition, for water enterprises in the formulation of corporate strategy, the assessment objectives as a starting point. The first thing an enterprise needs to consider is whether the assessment is the growth of scale or the growth of business revenue, and the path is different under different standards. Some companies are thinking about scale expansion and how much future assets they would have if they paid a certain price per ton of water.

In terms of sewage discharge standards, statistics are carried out from the two dimensions of the current sewage discharge standard and the functional target of the receiving water body. Beijing standard B will be implemented for about 60% of projects, and Beijing standard A will be implemented for around 20.Beijing has relatively special requirements in terms of standards due to some problems such as reuse of tailwater and supplement of landscape water. In Tianjin project, landmark B accounts for 37%, while landmark A accounts for 39%.In Hubei, Shanghai and Guizhou, grade A is dominant, but grade B in Hubei and Guizhou also has A certain proportion. It is not recommended to use the current emission standards to push back the expansion of enterprises in the market. There is still a certain proportion of sewage treatment projects in the wood powder province to implement the level I B standard, but it does not mean that it has a large need for bidding, so it can only meet the discharge standard. In addition, there are some special places, such as Anhui, which have special standards due to Chaohu lake and requirements for watershed management in the great protection of the Yangtze river.

The Balanced Elliptical Motion Shaker developed produced by KOSUN has obvious advantages.

The Balanced Elliptical Motion Shaker developed produced by KOSUN has obvious advantages in dealing with high-viscosity drilling fluid. In this case, the large particles in drilling fluid can be effectively removed through the balanced elliptical motion shaker track, and the relatively mild vibration intensity can effectively reduce the consumption of the shaker.

Balanced Elliptical Motion Shaker is the fourth generation of new mud shaker. In the past mud shale shaker mainly used linear shaker, but now more and more drilling companies choose balanced elliptical motion shaker.

With the development of drilling technology, drilling depth is getting deeper and deeper, and the requirement of mud is becoming more and more strict. Some complex geological conditions under the ordinary mud vibration screen cannot meet the requirements of use. And the performance of ordinary drilling vibration screen is not very stable, the effect of drilling vibration screen treatment will be different according to the drilling address and cannot adapt, often there will be some running slurry or “horseshoe effect”. The appearance of balanced elliptical motion shaker has solved these problems.

Advantages of Balanced Elliptical Motion Shaker:

1. The handling capacity increases by 25%-30% compared with the linear vibrating screen;

2. Can adapt to a variety of geological conditions drilling mud recovery and purification;

3. Excitation force can be adjusted;

4. Linear vibration type has the advantages of translational elliptical vibration screen;

5. Balanced elliptic trajectory can effectively reduce the blocking phenomenon of sieve holes and ensure the sieve penetration rate;

6. Help to improve the cuttings transportation speed in viscous drilling fluid and prevent paste screen;

7. Can handle high specific gravity and high viscosity drilling fluid;

8. Longer screen life;

9. Drier cuttings;

10. Quick tensioning system, easy to replace screen.
