Embodiment Construction

[0023] Please refer to the attached figure 1 . The present invention consists of a sump 1, a spherical filler 2, quartz sand 3, gravel 4, cobblestone 5, a sludge bucket 6, a mud discharge pipe 7, a partition 8, a water outlet 9, an outlet pipe 10, a vent pipe 11, and a water inlet 12, water outlet 13 forms. The device is made of PVC material, and is divided into two chambers, A chamber and B chamber, by a partition 8, A chamber adopts upward flow, and B chamber adopts downward flow. Cobblestones 5 and gravels 4 are laid on the bottom of chambers A and B as supporting layers, and a layer of quartz sand 3 and a layer of spherical packing 2 are alternately laid on the supporting layer, and so on up to the top, and the packing layer of chamber A is larger than that of chamber B. 10-15cm high. The laying height of cobblestone 5 in room A is from the bottom to the water inlet 12. On the cobblestone 5, an average particle diameter of 1-8cm and a thickness of gravel 4 of 0.05-0.8m ...

Abstract

The invention is an artificially reinforced soil percolation sewage processing device, relating to a device for processing sewage water for a city sewage treatment plant by soil, divided into rooms A and B by baffle, where the bottom of the two rooms are both laid with cobble and gravel as bearing layers, each of which is alternatively laid with gravel and spherical filling layers until the top. And the bottoms of the two rooms are provided with mud bucket and mud discharge pipe, respectively, and their ends are provided with water collection and outlet tanks, respectively; the upper part of the water outlet tank is made with water outlet pipe and the lower part is made with emptying pipe. And there are barrier-shaped water inlet and outlet arranged between the water collection tank and the room A and between the water outlet tank and the room B, respectively. And the device is simple and easy to operate, and able to process domestic sewage and some industrial waste water, especially applied to process domestic sewage in small towns.

Description

technical field [0001] The invention relates to a device for using land to treat sewage from urban sewage plants, and belongs to the technical field of sewage ecological treatment. Background technique [0002] my country is one of the 13 water-poor countries in the world, and its per capita water volume is only a quarter of the world's average level, ranking 110th among 149 countries in the world. Currently, 400 of the more than 600 municipalities across the country are short of water, and more than 130 of them suffer from severe water shortage. Cities across the country are short of 6 billion m of water every year 3 , the daily water shortage has exceeded 16 million m 3 , with an increasing trend. In fact, many areas are not without water, but without usable water. According to the sampling survey of sewage outlets in six major river basins across the country organized by the Ministry of Water Resources, the current annual sewage discharge in t...
