Problems solved by technology

The principle of using oxygen as a gasification agent is similar to that of air, the reaction rate is accelerated, and the thermal efficiency is improved, but the oxygen production equipment is too expensive and there may be certain safety problems in the process of using pure oxygen
CO 2 When used as a gasification agent, it has a positive effect on the gasification process under high temperature and pressure conditions, but the rate is significantly slower

Abstract

The invention relates to a process and system for treating high-concentration organic wastewater and organic solid waste. The device includes a high-pressure hydrothermal reaction kettle (1), and a pressure vessel (1‑2) is arranged in the hydrothermal reaction kettle (1) to separate solid and liquid connected to the solid-liquid separator (2), the solid-liquid separator (2) is connected to the dryer (3) and the compression molding machine (4), the liquid outlet is connected to the liquid storage tank (6), and the liquid storage tank (6) passes through The air circulation pump (5) is connected with the gasification reactor (7), and the gasification reactor (7) is connected with the gas storage tank (9) through the condenser (8). The invention converts high-concentration organic wastewater and organic solid waste into coke briquette fuel and high-quality hydrogen-rich combustible gas with high added value. On the one hand, the hydrothermal liquid phase and high-concentration organic wastewater can be cleaned and recycled. On the one hand, it improves the H in the organic solid waste gasification gas 2 content, realizing the high-value utilization of high-concentration organic wastewater and organic solid waste.

Description

technical field [0001] The present invention relates to the field of organic wastewater and organic solid waste treatment, especially to a high-concentration organic wastewater and organic solid waste treatment system, and also to a high-concentration organic wastewater and organic solid waste treatment process, which is suitable for organic wastewater such as domestic wastewater and industrial wastewater, It is suitable for organic solid waste such as agricultural and forestry waste, livestock waste, and high-humidity sludge. Background technique [0002] With the continuous growth of domestic population and economy, and the acceleration of urbanization, a large amount of urban domestic wastewater and industrial wastewater rich in organic matter is discharged into rivers and lakes, and a large amount of organic solid waste is improperly treated, resulting in serious organic pollution of the environment. According to statistics, the total amount of wastewater discharged in m...
