Description

Technical Field

[0001] The invention relates to the technical field of sewage or micro-polluted water treatment, and in particular to a modular loess-based modified filler landscape pond water purification system. Background Art

[0002] At present, in some areas far from cities and with incomplete municipal sewage pipe networks, such as scenic tourist areas, resorts, sanatoriums, villa areas, etc., where sewage is discharged in a dispersed manner, conventional secondary biochemical treatment technology is often difficult to be well applied. The integrated modular natural treatment system, while purifying sewage, provides conditions for the existence of biodiversity, and becomes the best place for people to return to nature and get close to nature, and is a good choice for beautifying the urban environment.

[0003] Clay minerals have good adsorption and ion exchange properties due to their unique layered structure. Loess is mainly distributed in the relatively dry mid-latitude zones of the world's continents, accounting for 1 / 10 of the country's land area. The Loess Plateau in northwest China is the largest loess plateau in the world. Loess is a natural inorganic mineral material of the silicate type, and its components are mainly SiO2, Al2O3 and CaO, and also contain Fe2O3, MgO and other components. Clay minerals such as loess, montmorillonite and bentonite are abundant natural adsorbents, but they have low organic carbon content and small specific surface area, so they need to be modified. The adsorption rate of loess can be improved through inorganic modification, and one of the more commonly used methods is calcination. The calcination modification is to make the loess lose organic matter, adsorbed water, interlayer water and structural water through high-temperature calcination, reduce the adsorption resistance of the water film to pollutants, and accelerate the diffusion of adsorbate molecules, thereby changing the adsorption performance of loess. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a modular loess-based modified filler landscape pond water purification system which is simple to operate, low in cost and has good treatment effect.

[0005] In order to solve the above problems, the modular loess-based modified filler landscape pond water purification system described in the present invention is characterized in that: the system includes a baffle pretreatment pool and a landscape pond buried underground and an automatic control system operating cabinet placed on the ground; a detachable tempered glass viewing corridor is laid on the baffle pretreatment pool and the landscape pond; an inlet pipe is provided on the upper part of one side of the baffle pretreatment pool, and the pool body is divided into three compartments by a folding plate, a semi-soft filler with a filling degree of 40% is added to the third compartment, and the third compartment is connected to the landscape pond; a drainage pipe is provided on the upper part of one side of the landscape pond, and a sludge discharge pipe connected to a sludge pump is provided on the lower part, and the drainage pipe is provided on the upper part of one side of the landscape pond. Three transverse partition walls are arranged perpendicular to the direction of water flow, dividing the pond into four compartments, each compartment is provided with a modular filler stainless steel frame; a landscape pond matrix is ​​arranged at the bottom of the landscape pond, and submerged plants and an air distribution pipe connected to a Roots blower are evenly distributed on the landscape pond matrix; a microporous aeration disk is arranged on the air distribution pipe; a plurality of modular filler brackets arranged in a matrix are arranged in the middle of the landscape pond, and a window screen and a loess-based modified filler placed in the window screen are arranged on the modular filler bracket; a constant temperature control device and floating plants are arranged on the upper part of the landscape pond; the sludge pump and the constant temperature control device are respectively connected to the automatic control system operation cabinet.

[0006] The water inlet pipe, the drainage pipe and the mud discharge pipe are all provided with electric control valves, and the electric control valves are connected to the automatic control system operation cabinet.

[0007] The electric control valve, the sludge pump and the constant temperature control device are respectively connected to the automatic control system operation cabinet through control cables.

[0008] The loess-based modified filler is a round particle with a particle size of 3-6 mm formed by mixing coal gangue, loess and bentonite from the northwest region in a weight ratio of 5:4:1 and calcined at a high temperature of 120°C.

[0009] The diameter of the microporous aeration disk is 9 cm.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. The present invention adopts an underground design with a detachable tempered glass viewing corridor laid on top. While improving the traditional water treatment environment, it can save a lot of land resources and has a certain landscape viewing effect.

[0012] 2. The packing area of ​​the present invention adopts modular design, and many packing modules are installed on a packing bracket that can be removed separately.

It is more convenient and quicker to clean or replace the packing than the traditional process.

[0013] 3. The filler selected in the present invention is a loess-based modified filler, the raw material of which is loess which is widely distributed in the northwest region, is cheap and easy to obtain, and has a good treatment effect.

[0014] 4. The microorganisms in the sewage of the present invention are attached to the loess-based modified filler in the form of a biofilm, and the pollutants in the sewage are removed by the biodegradation of the microorganisms, and then the physical filtration of the filter material can further enhance the effluent quality.

[0032] Three horizontal partition walls are arranged along the water flow direction in the landscape pond II, dividing the pond into four compartments, and the polluted water flows up and down from compartment to compartment; an aeration device, a landscape pond matrix 15 and a submerged plant 14, duckweed, are arranged at the bottom of the landscape pond II, and air is blown by a Roots blower 5. The air is distributed through the air distribution pipe 6, and then tiny bubbles are generated through the microporous aeration disk 7 with a diameter of 9 cm and dissipated into the polluted water. The landscape pond matrix 15 is loess-based modified ceramsite with a particle size of 8~10mm. Submerged plants 14, duckweed, are planted on the landscape pond matrix layer 15 to enhance the purification capacity of the system; a plurality of loess-based modified filler 12 modules arranged in a matrix are arranged in the middle, and the loess-based modified filler 12 is placed in a modular filler stainless steel frame 10 and supported by a window screen 11. The filler module can be individually detachably installed on the filler bracket 13. When the inlet water quality suddenly changes, a filler module is blocked or needs to be replaced, it can be Take out the packing unit for cleaning or replacement, and put it back to the designated position after meeting the requirements; the upper part is provided with a constant temperature control device 9 and a floating plant 8 duckweed, the constant temperature control device 9 can keep the water temperature in the landscape pond II constant, so that the growth and reproduction of water treatment microorganisms can reach the best state, the floating plant 8 duckweed can release oxygen into the water body through photosynthesis, promote the growth and reproduction of microorganisms, and its roots also provide a good environment for the attachment and growth of microorganisms, and on the other hand, it also increases a certain landscape viewing effect; the sludge in the landscape pond II is regularly sucked to the ground by the sludge pump 17 through the sludge discharge pipe 4, and then recycled.
