Self-cleaning and multi-filtration domestic sewage purification device

Abstract

The invention discloses a self-cleaning and multi-filtration domestic sewage purification device. The device comprises a buffer tank, a settling chamber, a spray cavity, a filter chamber and a filterdrum, wherein the buffer tank is cylindrical, a sewage input pipeline allowing domestic sewage to be input is arranged at the top of the buffer tank, and a sewage valve for controlling sewage flow isarranged at an outlet end of the sewage input pipeline; a guide groove is formed in the bottom of the buffer tank, and a prismatic delivery pipeline communicated with the settling chamber is arrangedat the bottom of the guide groove; a lifting pipeline communicated with the spray cavity is arranged at the bottom of the settling chamber, a cleaning pipeline communicated with the upper end of the lifting pipeline, and chemical liquor input in the cleaning pipeline can flow into the settling chamber and the spray cavity. According to the self-cleaning and multi-filtration domestic sewage purification device, the cleaning pipeline is communicated with the upper end of the lifting pipeline, so that the chemical liquor input in the cleaning pipeline can flow into the settling chamber and the spray cavity, the lifting pipeline and the spray cavity are cleaned regularly, work faults are reduced, and service life is prolonged.

Description

technical field [0001] The invention relates to the field of domestic sewage purification, in particular to a self-cleaning multi-filter domestic sewage purification device. Background technique [0002] At present, there are no special standards and specifications for the water consumption of living buildings, and generally refer to the "Code for Design of Water Supply and Drainage for Buildings" for selection. Domestic water for ships includes toilet flushing, laundry, catering, etc. [0003] The generation and discharge of domestic sewage is usually unstable, and its flow is also unstable. According to the investigation of the sewage of living buildings on the KL10-1 platform, the maximum daily sewage volume occurs between 7:00 am and 8:00 am, and the sewage volume can reach 50L / h. Compared with the daily sewage volume of 250L / d, it can be seen that The coefficient of variation is 1:5. For living buildings, the amount of domestic sewage fluctuates greatly, and there ma...
