Description

Internal combustion type waste water separating device

Technical Field

The invention relates to the technical field of wastewater treatment, in particular to an internal combustion type wastewater separation device.

Background

For municipal sewage treatment, sewage treatment plants generate a large amount of residue, sludge, each day due to the huge amount of water treated each day, and anaerobic digestion of sludge generated in the sewage treatment process to remove organic components is a commonly used method in order to avoid secondary pollution, so anaerobic-aerobic activated sludge method (a/O method, anaerobic/Oxic) is mostly adopted.

And will be accompanied by the production of biogas during the process. In order to realize the full utilization of the chemical energy of the biogas, the biogas is applied to the sewage treatment process, the biogas is combusted in a cylinder to do work, and the heat in the discharge of lubricating oil, intercooler, cylinder sleeve water and tail gas in a gas internal combustion engine is fully recycled by utilizing a heat recovery technology to form a heat power unit to heat a digestion tank. Meanwhile, sulfides in the biogas can corrode equipment (a turbocharger and a intercooler) particularly obviously; the service life of the lubricating oil can be reduced; if the tail gas heat exchanger is corroded, hot circulating water enters the cylinder body and the air cylinder of the internal combustion engine to cause larger loss, and because the hydrogen sulfide in the biogas is completely removed with certain difficulty, the humidity in the gas is an indirect condition for generating acid substances. Therefore, a dehumidification step of the gas is required.

The main means of the current wastewater treatment are physical treatment, biological treatment and chemical treatment, wherein the activated carbon adsorption method in the physical treatment can be used together with the activated sludge method, in the process, powdered activated carbon is used, the powdered activated carbon can adsorb substances which are toxic to microorganisms and is finally collected together with the sludge, the prior art has the problems that the activated carbon is positioned in a reaction tank and is difficult to replace and clean, the sludge generated by adsorption can block the water inlet and outlet ends of the reaction tank, and the most important danger of the activated carbon method in the wastewater treatment process is that the failed activated carbon can be always present in water and is difficult to remove.
