The invention provides a resource processing system and method for a manure and urine waste liquid of a train stool collector. The system comprises a fully mixed type anaerobic fermentation device, anitrogen and phosphorus recovery device, an integrated anaerobic ammonia oxidation biological coupling device and a compound electric ozone catalytic device; a water inlet is arranged at the bottom ofthe fully mixed type anaerobic fermentation device, and a water outlet pipe of the fully mixed type anaerobic fermentation device is connected with a water inlet of the nitrogen and phosphorus recovery device through a lifting pump; a water outlet pipe of the nitrogen and phosphorus recovery device is connected with the integrated anaerobic ammonia oxidation biological coupling device; a water outlet pipe of the integrated anaerobic ammonia oxidation biological coupling device is connected with a water inlet of the compound electric ozone catalytic device; a water outlet pipeline of the compound electric ozone catalytic device is connected with a water collection pool. The manure and urine waste liquid of the train stool collector is treated by the system, effluent can achieve zero discharge, 80% of phosphorus resource recycling is realized, treatment of the manure and urine waste liquid of the train stool collector with low energy consumption and low cost is realized, and the recovery and utilization of nitrogen, phosphorus and water resources are realized.
Description
technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a resource treatment system and method for excrement and waste liquid of train toilet collectors. Background technique [0002] By the end of 2016, my country's railway operating mileage reached 124,000 kilometers, and the annual passenger transport volume was 2.814 billion (an increase of 1 billion compared with 2012). According to the estimation method, each passenger train produces an average of 2 tons of toilet sewage per day, and more than 14,000 tons per day, and more than 5.2 million tons of toilet sewage will be produced throughout the year. According to the former Ministry of Railways' "Plan for the Reconstruction of Airtight Toilets for Railway Passenger Trains", toilets are gradually installed on normal-speed trains, and toilet systems are installed on all newly produced normal-speed trains, high-speed trains and high-speed trains. With the installation of a l...
