Description

Technical Field

[0001] The utility model belongs to the technical field of resource utilization, and in particular relates to equipment for comprehensive resource utilization of rural domestic sewage and organic garbage. Background Art

[0002] Random discharge of rural domestic sewage and organic waste pollution are common environmental problems in rural areas. With the acceleration of urbanization, the treatment of rural domestic sewage and organic waste has become increasingly prominent, becoming a bottleneck restricting the sustainable development of rural areas. Rural domestic sewage is divided into "grey water" and "black water", which mainly comes from the following aspects: 1. Kitchen sewage (grey water): including sewage generated during washing dishes and cooking; 2. Personal hygiene and household cleaning sewage (grey water): including sewage generated during bathing, laundry, etc.; 3. Human and animal feces sewage (black water): including sewage generated by flushing toilets. In rural areas, due to the lag in infrastructure construction and relatively weak environmental awareness, the treatment of grey water is often neglected. Many farmers do not establish a grey water treatment system, but choose to discharge grey water directly into rivers, lakes or fields. This practice will not only lead to eutrophication of water bodies and affect the balance of water ecology, but also have a negative impact on the soil quality of farmland, thereby affecting the growth and quality of crops. Black water is basically collected using septic tanks, most of which are three-chamber septic tanks. The three-chamber septic tank consists of three connected tanks, which are connected by a manure pipe in the middle. It mainly uses the principle of anaerobic fermentation, the middle layer of manure and the parasite eggs having a higher specific gravity than the general mixed liquid and are easy to precipitate. The feces are fermented and decomposed in the tank for more than 30 days, and the middle layer of manure liquid flows from the first tank to the third tank in turn, so as to achieve the purpose of precipitating or killing the parasite eggs and intestinal pathogens in the feces.

[0003] The traditional three-chamber septic tank has the following shortcomings:

[0004] (1) The traditional three-chamber septic tank can only provide primary transitional treatment for domestic sewage. If the treated sewage is not collected and treated by subsequent pipe networks, it will still pollute the local environment. At present, the construction of rural sewage treatment facilities in my country is relatively weak, and many villages do not have sewage collection and treatment systems;

[0005] (2) In villages with sewage pipe networks for collection and treatment, the traditional three-chamber septic tank sewage treatment model is mostly "septic tank + pipeline transportation + terminal treatment". The biggest disadvantage of this model is that it causes water waste. The useful resources N and P contained in feces and urine cannot be used, which is not in line with the concept of ecological development;

[0006] (3) In the traditional three-compartment septic tank treatment model, specialists are required to regularly operate and maintain the sewage transmission network and terminal treatment equipment. In addition, rural residential buildings are scattered, which is not conducive to operation and maintenance management. This traditional treatment model has a large initial investment cost and relatively high operation and maintenance costs;

[0007] The treatment of organic waste in rural areas often falls into the dilemma of no one to manage. Due to the lack of sufficient classification and recycling system, a large amount of organic waste is discarded at will, which not only seriously pollutes the environment, but also threatens the sustainable development of rural ecology. These organic wastes mainly include crop residues, livestock and poultry manure, domestic garbage, etc., which contain rich organic matter. However, due to the lack of scientific treatment methods, these precious resources are often wasted and even become a burden on the environment. Traditional organic waste treatment methods, such as landfill and incineration, not only occupy land, consume energy, and easily produce secondary pollution, but also fail to make full use of the organic matter in the garbage, resulting in a waste of resources. Therefore, the resource utilization of organic waste has become a hot spot and difficulty in current research.

[0008] Therefore, the utility model proposes a device for comprehensive resource utilization of rural domestic sewage and organic garbage to solve the above problems. Utility Model Content

[0066] This equipment has strong applicability:

[0067] Domestic sewage and organic waste fermentation liquid are collected into the fermentation liquid storage tank 8 through pipelines to avoid the adverse effects of sewage discharge on the environment. The equipment can calculate the daily drainage volume according to the permanent population of the residents and design the number of sewage resource utilization modules 9. The sewage resource utilization modules 9 can be placed in a dispersed manner to make full use of the idle space in front of and behind the house. The excess fertilizer liquid can also be drip-irrigated to the nearby vegetable garden, orchard, forest garden and other five small gardens. Each unit of the equipment is connected with a UPVC pipe, which is also applicable to mountainous areas with large terrain differences;

[0068] The equipment has low investment and operation and maintenance costs:

[0069] This equipment has obvious advantages such as easy installation, good treatment effect, and resource utilization. It is especially suitable for use in rural areas with incomplete supporting facilities for sewage treatment and organic waste treatment. In addition, in the early stage of construction, this equipment does not need to lay a large-scale sewage collection network. Compared with the traditional "septic tank + pipeline transportation + terminal treatment" model, it reduces the construction investment cost by about 60%-70%, and also adds the function of resource utilization of organic waste. At the same time, there is no need to designate a dedicated person to operate and maintain the entire system, and the operation and maintenance costs can be almost ignored;

[0070] The economic benefits created by this equipment are considerable:

[0071] The upper end of this equipment can rotate a variety of vegetables, such as tomatoes, water spinach, water celery, etc., which brings ecological products and generates considerable economic benefits. According to calculations, the economic benefits of planting different vegetables are as follows (calculated based on the vegetable prices in Wuhu, Anhui):

[0072] vegetable <![CDATA[Yield per area (kg / m 2 )]]> Unit price (yuan / kg) Yield per mu (yuan) tomato 8 8 42688 Water spinach 16 12 128064 Wild Rice 5 20 66700 lettuce 3 6 12006 Water celery 21 10 140070 Lettuce 4 6 16008

[0073] This equipment can improve the utilization rate of fermentation liquid:

[0074] Black water fermentation and organic waste fermentation will produce high-concentration nutrient solution rich in nitrogen and phosphorus elements, which will directly act on plants and often cause seedling burn due to excessive concentration. The seedling burn phenomenon is manifested by the yellowing and shrinking of crop leaves, or even the death of the whole plant. This is because high-concentration fertilizers will increase the salt concentration in the soil, causing plant cells to lose water, damage the root system, and be unable to absorb water and nutrients normally. At the same time, high-concentration fertilizers may also cause an imbalance of microorganisms in the soil, destroy the soil structure, and further affect the growth of crops. Therefore, this equipment is connected to gray water for dilution and fermentation, which can effectively reduce the concentration of the fermentation liquid. While solving the problem of seedling burn, it increases the absorption and utilization rate of plants by 50%, and also solves the environmental pollution problem caused by the discharge of "gray water" to external water bodies;

[0075] This equipment is environmentally friendly:

[0076] This equipment is not only environmentally friendly, but also of great significance for promoting sustainable development in rural areas. This equipment transforms sewage and organic waste, which were originally regarded as waste, into valuable resources, which not only solves the problem of environmental pollution, but also creates economic benefits. At the same time, domestic sewage and organic waste can be transformed into organic fertilizer after resource treatment. In the case of sufficient fermentation liquid, there is basically no need to use chemical fertilizers, reducing dependence on chemical fertilizers.

[0077] This equipment improves the traditional pollution control mode:

[0078] This equipment solves the problem of rural domestic sewage and organic waste treatment, and promotes the upgrading of environmental protection technology in rural areas. The traditional treatment mode often relies on simple landfill, incineration and other treatment methods, which not only causes secondary pollution to the environment, but also wastes precious resources. This equipment turns waste into resources and realizes green, circular and sustainable development.

[0079] This equipment saves water consumption and water transportation costs:

[0080] This equipment helps to save precious water resources, make resource utilization of sewage, and reduce the amount of irrigation water required for planting. It has great practical significance for mountainous areas and water-scarce rural areas.

[0081] The working principle and use process of the utility model are as follows: a three-chamber septic tank 4, a finished garbage bin 1, a basin pool 5 and a grease trap 6 are arranged at the front end of the equipment; the effluent of the three-chamber septic tank 4, the organic garbage fermentation liquid and the effluent of the grease trap 6 flow into the grille well 7 through UPVC pipes by gravity, and the fermentation liquid storage tank 8 is placed behind the grille well 7. After the effluent of the grille well 7, it flows into the fermentation liquid storage tank 8 by gravity through the De110 UPVC pipe. The effluent of the fermentation liquid storage tank 8 is distributed to the sewage resource utilization module 9 through the infiltration pipe. The sewage resource utilization module 9 adds drip irrigation pipes to the surrounding vegetable gardens, orchards and woods. All the effluent is used by economic crops to realize ecological operation.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
