Description
Technical Field
The invention belongs to the technical field of sewage treatment, and particularly relates to a system and a method for treating and irrigating sewage in a new rural area.
Background
The rural domestic sewage refers to sewage discharged by a toilet and kitchen wastewater when people take a bath or wash clothes in the living process. At present, the treatment rate of domestic sewage in rural areas in China is low, most of the domestic sewage can be directly discharged without treatment or can not be discharged and treated in a centralized manner, and the living environment and the body health of vast rural masses are seriously influenced and threatened. The traditional rural sewage treatment method is to directly discharge sewage to receiving water or nearby farmlands after the sewage is treated by a septic tank. The recycling of rural sewage can effectively relieve the problem that part of irrigation water resources are scarce, but ammonia nitrogen, total phosphorus and other toxic and harmful substances of the rural sewage often seriously exceed the standard, and the rural sewage has the characteristics of unstable and small water quantity.
On the other hand, rainwater is an important water resource for reuse irrigation, and is often directly discharged due to lack of storage facilities in vast rural areas, so that water resource loss and waste and seasonal water shortage are easily caused. Rainwater is not widely used for reuse irrigation, and an important reason is that initial rainwater is polluted greatly and needs to be treated before being used. However, the independent establishment of the initial rainwater system is not suitable for the development level of rural economic society in China, and inevitably faces the problems of land occupation and cost.
If the sewage treatment system and the rainwater storage and regulation system can be organically combined, the sewage treatment system is utilized to treat rainwater with poor water quality, particularly rainwater with large initial pollution, so that the rainwater can reach the standard and be discharged; meanwhile, the rainwater storage and regulation system is fully utilized, the problem of shortage of rural irrigation water resources is solved, a multifunctional water resource treatment and utilization system and method are formed, and the method is an approach for effectively solving the technical problems.
Disclosure of Invention
Based on the above, the present invention aims to provide a new rural sewage treatment irrigation system and method.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a new rural sewage treatment system, the system includes sewage collection unit, rainwater collection unit, sand setting unit, ecological pond unit and constructed wetland unit that detains that loops through the pipe connection, wherein:
the ecological detention pond unit comprises a soil pond substrate and aquatic plants growing on the soil substrate; the aquatic plants are Equisetum rotundus, Foliumet sidum, Argasta crenata and Festuca arundinacea;
the artificial wetland unit is an up-flow vertical subsurface flow artificial wetland and sequentially comprises a water distribution area, a crushed stone layer, a zeolite layer, a coarse sand matrix layer, a soil matrix layer and aquatic plants from bottom to top. The up-flow vertical subsurface flow constructed wetland mainly strengthens the removal effect on TN and COD, a gravel layer is laid at the bottom, and the resistance of the water body flowing upwards is reduced by utilizing larger gaps among the gravels, so that the water flow is prevented from being short-circuited, and the water flow can form a canal flow; meanwhile, the larger specific surface area of the macadam substrate is beneficial to microorganisms to be attached to the macadam substrate, and the attached microorganisms have good removal effect on COD; the zeolite layer is laid on the crushed stone layer, so that the adsorption effect on TN can be enhanced. The coarse sand matrix has a filtering effect and can effectively prevent the wetland from being blocked.
The ecological retention pond has the effects that pollutants in a particle state or adsorbed by particles are removed through sedimentation of tiny suspended particles (TSS), the pollutants in the particle state are prevented from entering the artificial wetland, and soluble organic matters (COD), Total Nitrogen (TN) and Total Phosphorus (TP) in a water body are removed through the absorption of aquatic plants.
The surfaces of the aquatic plants can be used as growth media of microorganisms, the flow state of water flow in a detention pond can be changed, meanwhile, the morphological structure of the aquatic plants and the combination of the aquatic plants and other aquatic plants have great influence on the microenvironment of a water body, the influence can influence the removal effect of integral COD (chemical oxygen demand), micro suspended particulate matters (TSS) and the like to a certain extent, and in addition, the mutual influence among the plants is usually ignored in the existing research.
Through a large amount of experiments and screening, the interaction between different aquatic plants is researched according to the configuration and parameters of the ecological detention pond, and the most suitable aquatic plant combination is obtained.
