Embodiment 1

[0038] Such as figure 1 , a domestic sewage cascade pool based on anaerobic ammonium oxidation, comprising a treatment pool 1, the treatment pool 1 includes a main body, an interlayer 3, and a water outlet; two long sides of the treatment pool 1 are symmetrically provided with positioning grooves 4, so that The two ends of the interlayer 3 are inserted into the positioning groove 4, and the interlayer 3 divides the treatment pool 1 into a plurality of independent small pools, that is, the cascade pool 2; the interlayer 3 is provided with a water hole 5 To make a plurality of cascaded pools 2 communicate with each other, wherein the water holes 5 on two adjacent interlayers 3 are respectively arranged on the top of the interlayer and the bottom of the interlayer, so that the sewage in the treatment pool 1 presents a U-shaped flow.

[0039] Further, the depth of the treatment pool 1 is 6-12m, and the width is 10-15m. The length of the treatment pool 1 is calculated according to...

Embodiment 2

[0048] In this example, the domestic sewage cascade pool based on anaerobic ammonium oxidation is applied to the purification of constructed wetland, which specifically includes the following operations:

[0049] (1), the construction of treatment pool 1: excavate a square treatment pool near the position of the sewage source, the depth of the treatment pool is 6m, and the width is 10m. The length of the treatment pool is calculated according to the formula L=V / W×H×5m, wherein, L is The length of the treatment pool to be dug, V is the volume of sewage treated every day, W is the width of the treatment pool to be dug, and H is the depth of the treatment pool to be dug. The wall and bottom of the pool are poured with steel skeleton and concrete according to conventional methods to ensure firmness and impermeability. Set a water outlet hole with a diameter of 30cm at the bottom of the end of the treatment tank;

[0050] (2), the setting of cascading pool 2: the long side of the ...

Embodiment 3

[0060] In this example, the domestic sewage cascade pool based on anaerobic ammonium oxidation is applied to the purification of constructed wetland, which specifically includes the following operations:

[0061] (1), the construction of treatment pool 1: excavate a square treatment pool near the sewage source, the depth of the treatment pool is 8m, and the width is 12m. The length of the treatment pool is calculated according to the formula L=V / W×H×6m, wherein, L is The length of the treatment pool to be dug, V is the volume of sewage treated every day, W is the width of the treatment pool to be dug, and H is the depth of the treatment pool to be dug. The wall and bottom of the pool are poured with steel skeleton and concrete according to conventional methods to ensure firmness and impermeability. Set a water outlet hole with a diameter of 50cm at the bottom of the treatment tank;

[0062] (2), the setting of cascade pond 2: the treatment pond 1 long side that has built in s...

Abstract

The invention relates to a domestic wastewater cascaded pond based on anaerobic ammonia oxidation and a constructed wetland purifying method. The domestic wastewater cascaded pond comprises a treatment pond, wherein the treatment pond comprises a main body, partition layers and a water outlet; positioning grooves are symmetrically formed in two long sides of the treatment pond; two ends of each partition layer are inserted in the positioning grooves; the treatment pond is divided into a plurality of independent small ponds by the partition layers, and the independent small ponds are cascaded ponds; a water hole is formed in each partition layer, so that the cascaded ponds communicate with one another; the water holes of each two adjacent partition layers are separately formed in the top of the corresponding partition layer and the bottom of the corresponding partition layer, so that wastewater flows in the treatment pond in a U-shaped manner; and by combined action of substrate adsorption and microorganisms, nitrogen and phosphorus as well as heavy metal pollutions in the wastewater are purified. The domestic wastewater cascaded pond based on anaerobic ammonia oxidation has the advantages of low investment, quick effect, high efficiency, ecological environmental protection and the like.

Description

technical field [0001] The invention relates to a purification method for nitrogen-rich domestic sewage, in particular to a domestic sewage cascade pool and artificial wetland purification method based on anaerobic ammonium oxidation, belonging to the field of environmental engineering. Background technique [0002] Domestic sewage contains a large amount of nitrogen, phosphorus and other nutrients and heavy metal elements, which is one of the important factors causing environmental pollution. Sewage treatment plants can remove nitrogen, phosphorus and heavy metals in domestic sewage to achieve the purpose of purification. However, the construction and operation costs of sewage treatment plants are very high, which is inconsistent with the concept of energy-saving wastewater treatment that is increasingly valued. In the mid-1990s, Anammox (Anammox) was discovered in Europe. Anammox refers to the self-supporting Anammox bacteria under anaerobic conditions, using NH4+ as an e...
