Become a leading brand in the sludge dewatering machine industry,. The company is a professional sewage and sewage treatment equipment and solutions and Tongji University environmental protection field focus on investment in the national high-tech enterprises, its core products and technologies, including vertical piece of fiber cloth filter pool and pressure sludge depth dewatering system and stacked screw sludge dewatering machine, etc., the company covers the field of sewage treatment and solid-liquid separation field. Below you introduce some sludge dewatering machine brand related content.
Tongchen has 15,000 square meters of research and development, production base, including professional production workshop and advanced processing equipment, the company will always be the quality of products as life. Has established a perfect process control and management system in product development, procurement of raw materials, and then to manufacturing production, factory inspection. Its production of high-quality environmental protection equipment to ensure that rely on its perfect testing methods, sophisticated machining equipment and systematic quality assurance system and strict process control measures.
Currently the company has applied for and owns a number of patents and other intellectual property rights, with the Chen focus on research and development and independent innovative technology, the company's rapid development since its inception, and the registration of independent trademarks and brands, and has been recognized as a national high-tech enterprises, access to the Fifth Shanghai Scientific and Technological Enterprises Innovation Award and other honors.
The world's top 500 petrochemicals, CNOOC, as well as the nuclear group and Carrefour Group, have been applied with the environmental protection products and technologies, and in a number of municipal wastewater treatment plants, chemical and pharmaceutical and food and beverage industries are in a wide range of applications of the company's products.
The stacked-screw sludge dewatering machine produced by the company, the equipment in the dewatering treatment takes into account the hydrodynamic isotropy, thin-layer dewatering, extending the path of dewatering and proper pressure application,? Get rid of the previous generations of sludge dewatering equipment easy to clog, high energy consumption and complex operation and other technical problems, and further reduce energy consumption and water consumption, extend the service life of the equipment, to ensure the performance of the equipment dewatering, to achieve the goal of high efficiency and energy saving dewatering.
Selection
The sewage will produce a large amount of sludge after precipitation treatment, even after thickening and digestion, the water content is still as high as 96?%, the volume is very large, it is difficult to eliminate the disposal, it must be dewatered to improve the solidity of the sludge cake, in order to reduce the sludge heap of floor space.
Generally large and medium-sized sewage treatment plants are used mechanical dewatering. There are many types of dewatering machine, according to the principle of dewatering can be divided into vacuum filtration dewatering, filter dewatering and centrifugal dewatering three categories. In this paper, the domestic sewage treatment plant is often selected filter press (including belt filter press and plate and frame filter press) and centrifugal dewatering machine principle of operation, equipment selection should be considered as well as maintenance and operating costs and other issues for an introduction.
1,? Belt filter press by the sludge load fluctuations in the impact of small, but also has a low water content of sludge and stable work less consumption, management and control is relatively simple, the quality of the operation of the staff does not require high characteristics. At the same time, due to the belt filter press dewatering machine into the domestic earlier, there are a considerable number of manufacturers can produce this equipment. Decision-making in the construction of sewage treatment works, you can choose the belt filter press to reduce project investment. At present, most of the new domestic sewage treatment plants using belt filter press dewatering machine, for example, Beijing Gaobeidian Sewage Treatment Plant, a project of five dewatering machines are all belt filter press dewatering machine, the filter belt, roller pressure cylinder put into operation since the situation is good, so in the second phase of the selection of equipment is still the selection of this type of machine.
2, general plate and frame filter press compared with other types of dewatering machine, the cake has the highest solids content, up to ?35%, if the sludge from the reduction of the sludge heap occupies an area of consideration, the plate and frame filter press should be the preferred option. ? The way of moving the filter plate. Requirements can be fully automatic or semi-automatic through hydraulic a pneumatic device, the operation is not convenient? The filter cloth oscillation device, so that the filter cake is easy to fall off. Compared with other types of dewatering machines, the biggest disadvantage of plate and frame filter press is that it covers a large area. Beijing Gaobeidian sewage treatment plant a project to use the belt filter press and the Anshan Industrial Sewage Treatment Plant to use the plate and frame filter press as an example for comparison: Gaobeidian sewage treatment plant sewage treatment volume of 500,000t / d, sludge production of 1,852.5m3 / d, 92.63t / d of dry matter, the use of five German KLEIN-KS30 type belt filter press, the base of each filter press covers an area of only 2750 * 3500mm, the filter cloth oscillation device in order to make the cake easy to fall off. Only 2750*3500mm, Anshan sewage treatment plant for 22t/d, dry matter 275t/d, using six plate and frame filter press, each filter press foundation covers an area of 2400*12000mm, at the same time, due to the intermittent operation of the plate and frame filter press, low efficiency, operating room environment is poor, there is a secondary pollution, the domestic large-scale wastewater treatment plant has been rarely used.
The company's future will be in the company's related fields of core technology and market position of the leading edge to continue to play, and develop into a leading sewage treatment equipment and solutions provider, and the most competitive high-tech environmental protection enterprises. The company's production of dewatering machine in 2012 product sales ranked first in the country, the company launched the core of this system is the engineering facilities as well as system integration equipment, so that the discharge of sludge to improve the requirements of the diaphragm plate and frame filter presses compared to the equipment has a high pressure, the same amount of treatment, the filter plate area is only a quarter of the diaphragm filter presses, which saves the floor space. The above is about sludge dewatering machine brand, I hope it can help you!
