Cyclic utilization process of waste activated carbon centralized regeneration treatment center

Abstract

The invention relates to a cyclic utilization process of a regeneration treatment center, in particular to a cyclic utilization process of a waste activated carbon centralized regeneration treatment center. The process comprises the following steps of: replacing the activated carbon with saturated adsorption and feeding the replaced activated carbon to a regeneration center, discharging carbon from a waste carbon tank, and feeding carbon from a waste carbon blowing tank. According to the cyclic utilization process of the waste activated carbon centralized regeneration treatment center, by centralized treatment and recycling of waste activated carbon, enterprises do not need to undertake subsequent maintenance for treatment, and the cyclic utilization process is more environmentally friendly.

Description

technical field [0001] The invention relates to a recycling process for a regeneration disposal center, in particular to a recycling technology for a waste activated carbon centralized regeneration disposal center. Background technique [0002] High-concentration wastewater has complex and changeable components, high chroma, BOD / COD<0.15, poor biochemical properties, and difficult treatment. It belongs to heavily polluted wastewater and is used in many industries such as papermaking, printing and dyeing, coal chemical industry, pharmaceuticals, daily chemicals, rubber, and synthetic fibers. Highly concentrated wastewater is produced. [0003] The comprehensive treatment of high-concentration wastewater is the most difficult and complicated field of water treatment technology. [0004] General chemical parks have the following problems [0005] (1) The investment cost and operation cost of environmental protection facilities are high. With the promulgation and implement...

AI Technical Summary

Problems solved by technology

[0005] (1) The investment cost and operation cost of environmental protection facilities are high

With the promulgation and implementation of the new environmental protection law, enterprises in industrial parks have increased investment in environmental protection facilities and strengthened the operation and management of equipment. This will undoubtedly increase the operating costs of enterprises and bring certain benefits to the sustainable and healthy development of enterprises. obstacle

[0006] (2) The operation of environmental protection facilities is unstable

According to reports, environmental protection violations such as excessive sewage discharge in industrial parks often occur, which are mainly caused by two aspects: ① The environmental protection technology and process route selected by the park enterprises cannot meet the actual needs, and the equipment operation effect is often not good; ② The park enterprises The concept of environmental protection investment is immature, and the number of business owners who are willing to focus on social responsibility is small, and companies are unwilling or unable to devote more energy to the operation and management of environmental protection facilities

[0007] (3) Potential joint risks brought about by abnormal operation of environmental protection facilities of individual enterprises in the park

It is understood that due to the lack of attention to environmental protection by individual enterprises or the abnormal operation of facilities, the water quality entering the sewage pipe network is not up to standard, which will bring certain operational risks to the sewage plant

[0008] (4) The supporting facilities in the park are not perfect

The incomplete supporting sludge treatment facilities in the park will not be able to completely solve the environmental problems in the park
