Description

Technical Field

[0001] This invention relates to the field of organic agriculture, and more particularly to a treatment tank for detergent waste liquid from organic farms. Background Technology

[0002] Jiang Gaoming, an expert from the Chinese Academy of Sciences, stated that while modern agriculture, characterized by the widespread use of artificially synthesized chemical substances, has increased agricultural output and production efficiency, it has also brought about a series of problems, including agricultural environmental pollution, agricultural ecological damage, waste of agricultural resources, excessively high agricultural costs, depletion of farmland and aquatic products, aggravated soil acidification, intensified soil degradation, doubts about food security, changes in animal behavior, an increase in intractable diseases, endangered species, reduced biodiversity, difficulty in degrading pesticide residues, and loss of palatable taste in agricultural products.

[0003] Organic agriculture can help solve a series of problems brought about by modern agriculture. Organic agriculture prohibits the use of synthetic pesticides, fertilizers, herbicides, detergents, etc. People are accustomed to using laundry detergent to wash clothes, shampoo to wash hair, dish soap to wash dishes, soap to wash hands, and shower gel to bathe, etc. The inventor's preliminary research found that six types of household detergents that meet emission standards poison two common earthworms. These household detergents, after being diluted with tap water, are discharged and eventually flow into ponds, rice paddies, vegetable gardens, farms, and soil, thus affecting the organic status of fish, crops, vegetables, livestock, and fields. In existing technology, an authorized invention patent entitled "A Desert Rice Paddy Ecosystem (ZL 202110889263.2)" discloses a technical solution for diverting detergent to enclosed soil for planting trees. The disadvantages of this technology are that the trees block sunlight, occupy a large amount of space, and many trees inhibit the growth and fruiting of some vegetables.

[0004] The core ingredient in detergents is surfactant, which can be chemically synthesized or made from natural ingredients. The mainstream household detergent industry primarily uses synthetic surfactants. Organic farming prohibits the use of synthetic chemicals, including detergents. Organic farming requires locations far from cities, industrial areas, mines, highways, and polluted environments; therefore, transporting organic farm wastewater from household detergent farms to urban wastewater treatment plants via pipelines or other means is prohibitively expensive.

[0005] How can we develop organic agriculture while using household detergents? Current technology lacks a technical solution for developing organic agriculture while using household detergents. Summary of the Invention

[0006] To overcome the above-mentioned shortcomings of the prior art, the present invention provides an organic farm detergent wastewater treatment pond.

[0007] The technical solution adopted by the present invention to solve its technical problem is: an organic farm detergent waste liquid treatment pool, including a washing pool (1) and a washing room (16). The washing room (16) isolates the detergent waste liquid to prevent it from mixing with kitchen waste and toilet feces. The washing pool (1) collects and concentrates the detergent waste liquid to prevent it from polluting organic agriculture. The bottom of the washing pool (1) is rectangular, with a frame structure and reinforced concrete skeleton. Red bricks are laid between the reinforced concrete skeletons on both sides of the washing pool (1). A crossbeam is set as a partition (4) at the front middle section and the rear middle section of the bottom of the washing pool (1). Red bricks are laid between the partition (4) and the pool base (3). The partition (4) and the surrounding beam (7) are open. Pre-fabricated materials are placed on the partition (4). The inner and outer surfaces of the washing pool (1) with an elevation higher than the upper surface of the partition (4) are not waterproofed. The outer and bottom surfaces of the washing pool (1) with an elevation lower than the upper surface of the partition (4) are waterproofed. All parts of the inner surface of the washing pool (1) are not waterproofed. The cross-section of the surrounding beam (7) is square. Beam holes (9) are evenly arranged in the middle of the front and the middle of the back of the surrounding beam (7). The drying pipe (11) is placed in the beam hole (9) so that the elevation of the drying pipe (11) is lower than the pipe inlet (14). One side of the drying pipe (11) is sealed with a pipe cap (12). The other side of the drying pipe (11) is connected to a tee (13). The tee (13) is connected to the pipe inlet (14) with a thickened polyvinyl chloride plastic (PVC) pipe. The drying pipe (11), pipe cap (12), and tee (13) are connected. The imported (14) is made of thickened polyvinyl chloride (PVC) plastic pipe. The sponge pad (10) is made of rectangular thin sponge filled with water-absorbing non-woven fabric bag and sewn together. The sponge pad (10) is placed on the drying pipe (11) and the two short sides of the sponge pad (10) are aligned and sewn together. Three rows of water spray holes (15) are evenly arranged parallel to the axis at the bottom of the drying pipe (11) covered by the sponge pad (10). The top of the washing pool (1) is the roof (8). The roof (8) is a double-slope structure and made of transparent fiberglass. The washing pool (1) is built in the foundation pit (2). The gap between the foundation pit (2) and the washing pool (1) is filled with waste soil so that the upper surface of the partition (4) is higher than the surrounding ground. The washing room (16) is characterized by including a bathroom (17), a kitchen (18), and a basin connector (1). 9) Bathroom drain connector (20), sink connector (21), kitchen drain connector (22), pipe outlet (23). After use, kitchen utensils are first washed with clean water in the kitchen to remove food residue, and then sent to the kitchen (18) for detergent cleaning. The organic farm's manure is discharged through a separate piping system, which does not mix with the detergent waste liquid. The organic farm's detergent waste liquid is isolated and collected through the washing room (16), and then connected to the pipe inlet (14) through the pipe outlet (23) using a thickened polyvinyl chloride plastic (PVC) pipe. The detergent waste liquid is sprayed onto the sponge pad (10) through the sprinkler hole (15), and the water vapor evaporates through the sponge pad (10). The concentrated detergent waste liquid flows into the washing pool (1) and can continue to absorb water and evaporate water vapor through the sponge pad (10).Continue concentrating the detergent waste liquid.

[0032] Household detergent wastewater discharge is relatively large. It can be concentrated by atmospheric evaporation of water vapor in the detergent wastewater. Atmospheric evaporation is affected by a variety of factors. This invention increases the evaporation effect by using red bricks to absorb moisture. Red bricks are a common building material with high hardness and absorb water and moisture. Therefore, the side wall (6) is built with continuous red bricks from bottom to top. The inner surface of the washing pool (1) is not waterproofed in order to ensure that the red bricks absorb moisture from the bottom of the washing pool (1) and evaporate water vapor. Water vapor can evaporate from both the inner and outer surfaces of the side wall (6). The side wall (6) can also block the side wind and ensure that the wind blows only to the front and back. Towards; This invention improves the evaporation efficiency of detergent waste liquid by sunning it like a quilt. Cotton quilts are natural fibers and are prone to rotting when exposed to dirty water for a long time. Non-woven fabric is made of plastic and is not easy to rot. However, some non-woven fabrics do not absorb water. Sponges can absorb water but are not strong enough. Household detergents are used in large quantities during peak periods. Sponge pads (10) can be sprayed and absorbed from the top and bottom for 24 hours a day. A thin layer of sponge covered with absorbent non-woven fabric can achieve the purpose of water absorption, sufficient strength and not easy to rot. This invention accelerates the evaporation of seawater by setting a transparent roof (8) to allow light to pass through. The evaporation rate of detergent waste liquid on the cotton pad (10) is controlled by the double-slope structure on rainy days, which allows rainwater to flow to both sides and prevents rainwater from entering the washing pool (1). The washing pool (1) is open at the front and back to guide the wind direction to the front and back. The inner surface of the washing pool (1) is not waterproofed so that the red brick can fully absorb water. The outer surface and bottom of the washing pool (1) are waterproofed to isolate and seal the detergent waste liquid in the washing pool (1). This invention prohibits kitchen food waste from being mixed with detergent waste liquid. Kitchen food waste is a natural food waste. Such substances can be composted or used to cultivate high-protein earthworm feed. Kitchen water washing requires a separate pipeline system. Surface residue must be washed away with clean water. Kitchen utensils are only taken to the kitchen (18) for cleaning when detergent is needed. This invention prohibits the mixing of feces with detergent waste liquid. Feces are natural substances that can be made into organic fertilizer after decomposition, and feces easily produce unpleasant gases. If the concentration rate of detergent waste liquid in this invention is insufficient, causing detergent waste liquid in the washing pool (1) to be on the verge of overflow, it can be transported to an urban waste treatment plant by a waste liquid transport vehicle. This invention comprehensively utilizes various technical means such as red brick water absorption, wind direction control, sun drying of the "quilt", double-slope rain protection, fine-hole spraying, double-layer sponge, top-drenching and bottom-absorbing, outer waterproof layer, inner moisture absorption, and excessive removal to achieve the purpose of preventing detergent pollution of organic agriculture and preventing detergent from affecting organic qualifications.

[0033] The beneficial effects of this invention are:

[0034] ① Organic farms can use detergents without polluting organic agriculture or affecting their organic certification.

[0035] ②The sponge pad (10) is sprayed with water and absorbed continuously for 24 hours to evaporate water vapor.

[0036] ③ Washing pool (1) Isolates, treats, and concentrates detergent waste liquid.

[0037] ④ The laundry room (16) isolates detergent waste liquid to prevent it from being mixed with kitchen and bathroom waste.

[0038] ⑤ The red brick wall absorbs moisture continuously for 24 hours a day, accelerating the evaporation of water vapor in the detergent waste liquid.

[0039] ⑥ The sponge pad (10) will not be blown over and is not easily rotten.

[0040] ⑦ The roof (8) is transparent, allowing sunlight to shine directly on it, which accelerates the evaporation of water vapor and concentrates the detergent waste liquid, making it difficult for rainwater to flow in.

[0041] The goal is to develop organic agriculture while simultaneously using household detergents, avoiding any impact on the qualifications of organic farming, livestock and poultry breeding, and aquaculture. Current technology suggests that detergents may be present in ponds used for aquaculture, livestock and poultry drinking water, irrigation water for farmland, and water used for watering and washing vegetables. Piping detergents to urban wastewater treatment plants or non-organic agricultural areas is problematic, as organic agriculture requires locations far from these areas. Transporting detergents by water truck would incur excessive costs due to the construction of detergent storage tanks, water trucks, transportation costs, receiving costs, and labor costs. The inventors' preliminary research found that six commonly used household detergents are poisonous to two common earthworms. The effects of detergents on other crops, fish, livestock and poultry, vegetables, plants, trees, shrubs, herbs, insects, soil animals, and amphibians have not yet been studied. The inventor's previously filed invention patent, "A Desert Rice Paddy Ecosystem (ZL 202110889263.2)," disclosed a technical solution that diverts detergent into sealed soil for planting trees, which is a completely different technical solution from the present invention.

[0042] Household detergents dissolve in clean tap water, and the surfactants in them help remove dirt. To prevent household detergents from ending up in organic farmland, vegetable gardens, ponds, and livestock farms, detergent treatment technology is essential. This invention essentially solves the problem of detergent treatment technology in organic farms. More specifically, the invention's inventiveness lies in: first, diverting detergent wastewater to prevent dishwashing liquid from mixing with food scraps and laundry detergent from mixing with feces; second, isolating the detergent wastewater to prevent it from contaminating the soil, farmland, vegetable gardens, ponds, and livestock farms in organic agriculture; and third, concentrating the detergent wastewater to prevent it from overflowing into the surrounding organic agricultural environment due to its large volume. The agricultural environment contains livestock, fish, crops, vegetables, and soil organisms such as earthworms. Since earthworms don't have mouths, livestock can't speak, fish don't express feelings, and crops and vegetables don't directly show aversion or rejection to household detergents, those skilled in the art clearly haven't realized the widespread impact of detergents on the agricultural environment. The inventors discovered that diluting six of the most commonly used household detergents a thousandfold can kill two common earthworms within just a few hours. It is obvious that technicians in the existing detergent and organic agriculture fields have not realized that household detergent wastewater that meets emission standards can have such a significant environmental impact.

[0043] This invention addresses the problem of how to prevent household detergents commonly used by people in organic farms from polluting organic agriculture and affecting organic farming qualifications by diverting, isolating, and concentrating detergent waste liquid. Attached Figure Description
