Document Type and Number:
Japanese Patent JP5686675
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently raise a digested sludge solid concentration and enhance the sludge treatment capability in a digestion step by mixing a fluid biomass and a non-fluid biomass basically in a pump and piping and charging the mixture in a digestion tank.SOLUTION: This apparatus includes: a fluid biomass feeder pump 4 which supplies a fluid biomass, a screw conveyance part 11 which makes a non-fluid biomass 2 to be dropped from the lower part of a temporary reservoir to be confluent with the fluid biomass, and conveys the confluent fluid in one direction, a confluent loading pump 10 including a conveyance pump part 12 which is connected with the screw conveyance part 11 and quantitatively conveys and sends out the confluent fluid, a digested sludge circulation path 20 for circulating back the digested sludge pulled out of a digestive tank 30, and a mixing and loading means 23 which sends the confluent fluid into a circulation channel including the circulation path and the digestive tank from the confluent loading pump 10.
