Abstract

The invention relates to a wastewater and sludge treatment system taking coal and organic matters as raw materials, the wastewater and sludge treatment system comprises a coal and organic matter mixedmaterial pretreatment unit; a liquid pressurizing unit; an oxygen supply unit; a supercritical water oxidation reaction unit; an evaporation crystallization unit; a heat recycling unit; a gas-liquidseparation unit and a waste heat utilization unit. The supercritical water oxidation reaction unit comprises a supercritical water oxidation reactor, wherein a liquid inlet of the supercritical wateroxidation reactor is connected with a coal and organic matter mixed liquid outlet of the coal and organic matter mixed material pretreatment unit, a first oxygen inlet is communicated into the supercritical water oxidation reactor after being merged with the liquid inlet, and a second oxygen inlet is communicated into the supercritical water oxidation reactor after being merged with a wastewater / sludge inlet. The waste water and sludge treatment system and process using coal and organic matters as raw materials have wide application range, high efficiency and zero pollution discharge, can realize energy and resource recovery at the same time, and are particularly suitable for industrial waste water, sludge, high-concentration organic waste water and hazardous waste treatment.

Description

technical field [0001] The invention belongs to the field of coal clean utilization and hazardous waste harmless and resource-based treatment, in particular to a waste water and sludge treatment system and method using coal and organic matter as raw materials. Background technique [0002] The traditional form of coal utilization is mostly atmospheric combustion in the air. This form of combustion will not only release a large amount of nitrogen oxides and sulfur oxide gases, causing serious air pollution and severe smog, but also emits The high-temperature gas carries a lot of heat, the energy utilization rate is low, the strict control of the environment and the high cost of tail gas treatment have forced the emergence of new combustion technologies. [0003] On the other hand, in the field of industrial sewage treatment, the reduction has been emphasized for many years, but it has resulted in the lack of resource utilization and energy utilization technology. Chemical wa...
