Micro-sized building block type recycled water treatment equipment

Abstract

The invention is a micro-sized building block type recycled water treatment equipment, which comprises a suspend sludge bed, an impulse fluidized bed, an aerobic fluidized bed and a recycled water storage tank, wherein the suspend sludge bed is provided with a sewage water inlet in which a cloth hydrophone , an exaltation water pump and a water circulating pump are arranged. An impulse generator is arranged in the impulse fluidized bed which is filled with suspend biological padding; the exaltation water pump is arranged at the bottom of the impulse fluidized bed; the recycled water storage tank is positioned at the lower part of the impulse fluidized bed, and a cyclone mixer is arranged in the recycled water storage tank. The aerobic fluidized bed is arranged on the impulse fluidized bed, and a microstrainer and a water-jet device are arranged in the aerobic fluidized bed. A water jet pump is arranged outside the aerobic fluidized bed. The invention adopts two-stage anaerobic and a group of anaerobic-aerobic four-stage biological treatment technologies so as to be effective in processing all pollutants. The equipment needs small field occupation and has simple technology. The equipment can treat 8 to 12 cubic meters of sewage water daily with the occupation of 1 square meter and can recycle methane, which conform to the requirements of recycling economy.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to a miniature building block type reclaimed water treatment equipment which is suitable for purifying toilets and various medium and high-concentration sewage or disinfecting and reusing them. Background technique [0002] The existing reclaimed water treatment technology, whether it is buried underground or built on the ground, is bulky, occupies a lot of land and is expensive to construct, and the wastewater only undergoes 1-2 stages of biological treatment, filtration, and disinfection, and has low processing capacity for N and P. If the reclaimed water standard is not met, the water entering rivers, lakes, and oceans will cause eutrophication of the receiving water body, which is the cause of cyanobacteria and red tides. Contents of the invention [0003] The purpose of the present invention is to provide a method for treating all polluting substances in view of the defects that ...
