Embodiment 1

[0031] Such as figure 1 As shown, the present embodiment provides a water and soil conservation water quality purification method in a water source area, the method includes the following steps:

[0032] A. Multiple side slope ditches are excavated along the horizontal gradient on the side slope of the water source, and the side slope ditches are laid out along different altitudes. In this embodiment, one ditch is dug for every 5 meters of elevation of the horizontal gradient, and a total of 3 ditches are dug ; The depth of the side slope ditch is 50-150cm, the width of the ditch is 50-100cm, and a brick ditch is used to form a purification tank. Specifically, the side slope ditch is built with M7.5 cement mortar bricks, and M10 mortar is plastered;

[0033] B. Insert water pipes (32PE pipes are used in this embodiment) in the septic tank. The water pipes can connect the septic tanks with different horizontal gradients on the slope. The top of the purification tank is connect...

Embodiment 2

[0042] Such as figure 2 with image 3As shown, this embodiment provides a water and soil conservation water quality purification system in a water source area, including a plurality of purification tanks 1 arranged in sequence along the slope of the water source at different altitudes and water pipes for connecting adjacent purification tanks 1 with different horizontal gradients 2, and the septic tank 1 at the lowest position is connected with a drain pipe 3 to connect to the reservoir, and the septic tank 1 is set in the side slope ditch; the water pipe 2 is respectively connected to the bottom of the high septic tank 1 and the bottom of the low septic tank 1 The top is connected; the side wall of the purification tank 1 includes a cement mortar brick layer and a mortar plastering layer; the purification tank 1 is sequentially arranged with a graded sand filter layer 11, litter and microbial action layer 12, biochar Adsorption filtration purification layer 13 and rapid inf...

Abstract

The invention discloses a water source land water and soil conservation water quality purification method and a system. The method comprises the following steps: A, excavating a plurality of side slope ditches in a side slope of a water source land along a horizontal gradient, arranging the side slope ditches along different altitudes, and forming purification tanks through bricking the ditches; b, inserting water pipes into the purification tanks, wherein the water pipes can connect the purification tanks with different horizontal gradients on the slope surface; and C, sequentially adding a graded sandstone filter layer, a litter and microorganism action layer, a charcoal adsorption filtration and purification layer, and a rapid infiltration+grass seed soil layer into each purification tank from bottom to top in a layered manner. According to the system, the stability of the slopes can be enhanced, and water and soil loss of the slopes is effectively reduced. Meanwhile, the purification capacity of the existing water conservation forest and soil can be enhanced. The surface layers and the bottom layers of the purification tanks can accelerate infiltration, and meanwhile, the litter and microorganism action layers and the charcoal adsorption filtration and purification layers in the middles have a good purification effect on water, so that the aim of purifying the water can beachieved.

Description

technical field [0001] The invention relates to the technical field of ecological protection equipment, in particular to a water and soil conservation and water quality purification method and system capable of reducing soil erosion and purifying water sources. Background technique [0002] At present, the construction of water source conservation forest projects is dominated by traditional water conservation projects, which have very limited degradation of pollutants. Conventional sewage treatment technologies have poor removal effects on soluble organic matter, ammonia nitrogen, and odor. During the purification process, the system tends to breed algae to block the filter, and the algae metabolites can form toxic pollutants with three effects (mutagenic, teratogenic, and carcinogenic) after being disinfected by chlorine injection. Although traditional water conservation forests or wetlands can also purify water quality, they have such factors as large land occupation and ...
