Embodiment Construction

[0021] The present invention is described in further detail below in conjunction with embodiment.

[0022] like Figure 1-Figure 3 As shown, under normal circumstances, the wastewater from farmers’ kitchens (1) and bathrooms (2) is filtered and purified through gravel ditch (7) and then enters artificial wetlands (8). and livestock and poultry pens (4) sewage and excrement enter the biogas digester (5) through the pipeline system to ferment and produce biogas as fuel for the kitchen (1), and the produced biogas residue and biogas slurry are used as high-quality organic fertilizers for farmland (12). If the biogas residue cannot be transported to the farmland (12) in time, it is temporarily stored in the biogas residue stockpile (6); after the rainfall, the biogas residue stockpile (6) runoff, roof (9) runoff, and surface (10) runoff pass through the gravel ditch (7) After being collected, filtered and purified, enter the constructed wetland (8) for effective treatment, and th...

Abstract

The invention relates to a novel method for rural sewage treatment and resource recycling, which comprises component units of a gravel ditch, a marsh gas tank, a marsh gas residue stock dump, an artificial wetland and the like, wherein the gravel ditch plays certain role in filtration and purification of the collected sewage and wastewater, and can prevent the conventional drainage ditch from being filled with a large number of sundries outside the ditch; the marsh gas tank can achieve the resource recycling of the wastewater and waste materials; the marsh gas residue stock dump mainly prevents pollutant runoff, overflow and direct discharge caused by rainfall during stockpiling period of marsh gas residues; and the artificial wetland mainly plays a role in pollution treatment and has certain function of ecological landscape. The novel method for the rural sewage treatment and resource recycling not only can effectively treat the directly-discharged rural domestic sewage, but also can collect and treat rainfall runoffs embodied by village pollution intensively, and simultaneously, the method implements clean energy conversion and utilization of solid wastes, and achieves the aim of promoting rural ecological cycle while treating sewage.

Description

technical field [0001] The invention relates to the technical field of rural sewage treatment, in particular to a novel rural sewage treatment and resource recovery method. Background technique [0002] It has become a topic of great concern in the world, especially in the field of environmental protection in my country, to scientifically and effectively treat the large-scale and wide-ranging scattered point sources in rural areas to make them harmless and recyclable. Developed countries attach great importance to the pollution control and treatment of rural sewage. In 2002, the treatment rate of rural sewage in France did not exceed 50%, but in 2005 it realized all treatment of rural sewage. During the implementation process, the characteristics of high efficiency and low consumption of ecological treatment technology make it the preferred technology. Its market advantages also include : The natural treatment function is gradually recognized, the investment in traditional ...
