Problems solved by technology

[0003] Using biochemical system to decompose feces and urine wastewater is a method of using microbial fermentation technology to treat waste, but the ammonia component in feces and urine wastewater will reduce the decomposition efficiency of biochemical system, and the long-chain organic matter in feces and urine wastewater is not easy to be decomposed. These Both make the application of microbial fermentation to decompose feces and urine wastewater limited

Abstract

The invention discloses a railway excrement and urine wastewater treatment system. The system comprises an iron-carbon micro-electrolysis reactor, a magnesium ammonium phosphate reactor and a magnesium ammonium phosphate solid-liquid separation reactor. Each of the iron-carbon micro-electrolysis reactor, the magnesium ammonium phosphate reactor and the magnesium ammonium phosphate solid-liquid separation reactor is composed of a feeding hopper and a discharging hopper; and the iron-carbon micro-electrolysis reactor, the magnesium ammonium phosphate reactor and the magnesium ammonium phosphatesolid-liquid separation reactor are sequentially connected in series. A weighing grid and a micro-electrolysis filler are arranged in the iron-carbon micro-electrolysis reactor, and treated wastewateris introduced into the magnesium ammonium phosphate reactor to react with added materials to generate magnesium ammonium phosphate and finally enters a solid-liquid separator for settling and separation. The system can be used for carrying out an iron-carbon micro-electrolysis reaction treatment on high-concentration excrement and urine wastewater discharged by a train, long-chain organic mattersare broken, ammonia contained in the wastewater can be removed by generated magnesium ammonium phosphate, and a good condition is created for the treatment in a biochemical fermentation treatment system in the later period.

Description

technical field [0001] The invention relates to the field of feces and waste water treatment, in particular to a railway waste water treatment system. Background technique [0002] my country's high-speed rail industry is developing rapidly, and the operating mileage of high-speed passenger cars ranks first in the world. Centralized collection and fixed-point unloading of feces and urine in toilets have been implemented for all high-speed passenger cars, which has made a great contribution to environmental protection along the high-speed rail. However, due to the large unloading volume of high-concentration fecal and urine wastewater that is unloaded at fixed points, the unloading time is concentrated, the concentration of pollutants is high, and the composition is complex, it has particularity. The conventional domestic sewage treatment technology and facilities of the stations, sections, and institutes that accept unloading in the high-speed rail system are no longer suit...
