Embodiment Construction

[0008] The sewage treatment flow process of the embodiment of the present invention is:

[0009] (1) The sewage enters the grit chamber through the lifting pump station, and is removed after the sediment and suspended particles are settled;

[0010] (2) pressurize with a booster pump and enter the primary aerated biofilm reaction tank with fillers from the bottom;

[0011] (3) Enter the secondary aerated biofilm reaction tank with fillers from the upper outlet of the first-level aerated biofilm reaction tank;

[0012] (4) Enter the quartz sand filter from the upper outlet of the secondary aerated biofilm reaction tank;

[0013] (5) Enter the upper part of the activated carbon filter from the bottom of the quartz sand filter through the U-shaped tube;

[0014] (6) Flow through the disinfection system;

[0015] (7) The flow to the middle water pool is completed;

[0016] In the process, a blower is used to aerate the bottom of the first and second aerated biofilm reaction ta...

Abstract

The invention discloses a biological sludge zero discharge domestic sewage recycling treatment device. The device comprises a sand settling tank, first and second stage aeration biomembrane reaction tanks filled with fillers, a quartz sand filter tank, an active carbon filter tank, a UV disinfection system and / or a reclaimed water tank and the above units are orderly communicated through pipes or holes, an air pump is respectively communicated with aeration heads at bottoms of the first and second stage aeration biomembrane reaction tanks and the quartz sand and active carbon filter tanks, a backwash pump has a water inlet pipe connected to the reclaimed water tank and water outlet pipes respectively at the bottoms of the quartz sand and active carbon filter tanks, and the quartz sand and active carbon filter tanks are provided with pipes communicated with the first stage aeration biomembrane reaction tank.

Description

technical field [0001] The invention belongs to sewage treatment technology, in particular to a domestic sewage resource treatment device with zero discharge of biological sludge. Background technique [0002] With the increase of population and the rapid development of economy and society, the shortage of water resources has become the main problem seriously hindering economic development in many areas, directly affecting the sustainable development of my country's economy and society. The recycling of sewage is an effective way to alleviate the crisis of water resources. At present, the methods of recycling sewage can be roughly divided into three categories: biological method, physical chemical method and membrane method. Biological treatment is generally recognized as a low-cost sewage treatment technology, but the common limitation of biological methods is the generation of excess sludge, which requires subsequent treatment. According to statistics, in the infrastructu...
