Embodiment Construction

[0026] The collected high-concentration rural non-point source polluted wastewater is treated by the designed MSHIVFCW device. The size of the MSHIVFCW system structure is length × width × height = 2.5m × 1m × 1.2m. After the waste water flows into the device through the water inlet, it will further remove pollutants such as COD, ammonia nitrogen and phosphorus in the waste water after the physical, chemical and biological triple coordinated reactions of the complex ecosystem. After the high-concentration wastewater is treated, the discharged wastewater reaches GB5084-92 "Water Quality Standard for Farmland Irrigation".

[0027] The specific implementation process is as follows:

[0028] (1) After the rural non-point source polluted wastewater is collected, it can first pass through the interception of the grid to remove the large particles of pollutants and floating objects in the sewage, and then the wastewater enters the MSHIVFCW device.

[0029] (2) The waste water enters...

Abstract

The invention provides a serial drop water composite wetland system for treating the non-point pollution. The system is composed of a cuboid package, a wetland device, a wetland substrate and wetland plants; two same flow lines, namely a room temperature flow line 1 and a low temperature flow line 2 are connected in parallel to form the system; each flow line is composed of six cells and one water-collecting tank; and the wetland substrate has four layers, wherein the first layer, namely the topmost layer is a clay layer, the second layer is a fine sand layer, the third layer is the mixed layer of coal cinder and limestone and the fourth layer is a cobble layer. The device has the function of efficiently purifying sewage.

Description

technical field [0001] The invention relates to environmental engineering technical equipment, in particular to a treatment equipment for rural non-point source polluted wastewater. Background technique [0002] Rural non-point source pollution has a very significant contribution to the deterioration of the water environment, mainly including fertilizer pollution, pesticide pollution, and livestock and poultry breeding pollution, which are caused by soil particles, nitrogen, phosphorus, pesticides, and other organic or inorganic pollution in farmland caused by soil disturbance. Substances, in the process of rainfall or irrigation, enter the water body in large quantities by means of farmland surface runoff, farmland drainage and underground seepage, or directly cause water body pollution due to arbitrary sewage discharge from the livestock and poultry breeding industry. [0003] Constructed wetlands are artificially created artificial ecosystems that are suitable for the gro...
