Embodiment 1

[0017] The ecological treatment device for individual household drainage of the present invention is composed of an anaerobic filter tank 1, a diffuse water oxygenation tank 2 and a functional ceramsite underground percolation bed 3 connected in series; the front end of the anaerobic filter tank 1 receives the septic tank effluent through a baffle tube 4; The water distribution tank 2 is provided with a water separation tank 6; the functional ceramsite underground percolation bed 3 is composed of a capillary air-permeable layer 7, a water distribution tank 8, a functional ceramsite percolation layer 9 and a water collection layer 10 connected in sequence. ;

[0018] The sewage enters the anaerobic infiltration tank 1 through the baffle pipe 4, and the effluent from the anaerobic filtration tank 1 is introduced into the diffuse water aeration tank 2 through the water distribution pipe 5, and then distributed to the functional ceramsite underground percolation bed 3 through the w...

Embodiment 2

[0021] The length × width × height of the anaerobic filter tank of the retail type domestic sewage multi-media ecological treatment device is 0.3 × 0.6 × 1.2m, the length × width × height of the diffuse water aeration tank is 0.3 × 0.6 × 1.2m, and the distribution of water in the oxygen increase tank The length × width × height of the water tank is 0.2 × 0.3 × 0.25m, and the functional ceramsite underground percolation bed is 3 units with the same area, and the length × width × height of each unit is 1.2 × 1 × 1.2m respectively. 50cm from the ground. The particle size of functional ceramsite is 8mm, and the weight ratio of functional ceramsite: fly ash: biomass material: primary clay: waste iron ore is 70:15:10:5, a total of 6 layers are filled, and the permeable material is gravel: modified zeolite: ash The volume ratio of the slag is 80:10:10, and a total of 5 layers are filled. Under hydraulic load 15cm / m 2 In case d, influent COD200mg / L, NH 3 -N 20mg / L, TN 30mg / L, TP 5m...

Abstract

The invention relates to a device and a method for ecological treatment of private household type domestic drainage. The device consists of an anaerobic filtering tank, a water diffusion aerobic tank and a functional porcelain granule underground infiltration bed in serial connection. The detailed device structure and the method are shown as an instruction book. The device and the method have theadvantages that mass solid is intercepted through anaerobic filtering; activity of microorganism is increased through water diffusion and oxygen increase; an infiltration layer consisting of functional porcelain granules and zeolite filled through 'wall-bricking' nesting and filling is introduced to an underground infiltration gravity filtering section so that an underground infiltration system has good hydraulic conduction performance, high-efficiency self-desorption capacity, high hydraulic load, remarkable chromatographic effect of pollutants and uneasy blockage; a material for producing the functional porcelain granules has wide source, convenient machining and low cost; a water distribution mode of capillary adsorption increases a sewage purification path in the system and improves effective cubage of the system; and the device operates under powerless condition, does not increase building cost and is in particular suitable for deep treatment of villa and private household type domestic drainage.

Description

technical field [0001] The invention belongs to the field of sewage treatment, in particular to a device and method for the ecological treatment of individual household sewage. Background technique [0002] In the vast rural areas of our country, some scattered villages or independent residential units, if centralized treatment is used to treat domestic sewage, a large number of drainage pipe networks need to be built, and the cost is often difficult to bear. At this time, retail-type treatment facilities are more practical. However, some technologies have problems such as low hydraulic load and easy clogging, which limit their wide application in domestic sewage treatment in vast rural areas of our country. Therefore, the development of economically efficient, low-cost operation, and non-clogging retail-type rural domestic sewage treatment technology has broad demand and social needs in the vast rural areas and private villas in our country. Contents of the invention ...
