It can continuously feed, dehydrate and unload the feed liquid at full speed. It is a kind of separation equipment with novel structure, advanced technology, high efficiency and low consumption. The machine is widely used in petroleum, chemical, mining, pharmaceutical and other industries.

With the continuous improvement of the country’s environmental protection requirements, major oil fields are confronted with the problem of drilling waste disposal.

KOSUN’s VC-1000 series vertical cuttings dryer can be used for various types of drilling mud, mainly for oil-base and composite mud cuttings drying. Similar to other solid control equipment, such as vibrating screen, centrifuge, cyclone separator. The treatment ability of VC-1000 series vertical cuttings dryer also has a great relationship with mud viscosity. Mud viscosity is determined by many factors, including solids content, particle size, drilling fluid type and drilling fluid temperature.

Features and advantages of KOSUN’s VC-1000 series vertical cuttings dryer:

1. Efficient solid-liquid separation can minimize the mud content in drilling cuttings and reduce the amount of waste disposal;

2. Effective separation and a larger proportion of the recovery mud, and reuse in the mud circulation system, can recover the mud due to the vibration screen slurry, mobile derrick and screen blockage;

3. Common wear parts can be replaced from the top of the device, and the belt can be replaced without moving any device;

4. The scraper of inner rotating body is sprayed with tungsten carbide anti-corrosion and wear-resistant material, which can prolong its service life and reduce the maintenance cost.

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.
