Embodiment 1

[0042] Example 1: Arrange the collection pipeline at the bottom of the pool body, and then lay a 50nm pebble layer at the bottom of the pool body, with a filling height of 300mm; spread neutral volcanic rock on the top, with a particle size of 30-50mm, and a filling height of 400mm; A porous membrane for evenly distributing waste water is set between the material ginger stone layer and the filler layer; the processing particle size is 20-30 mm, and the filling height is 200 mm; then plant quinces on the top layer, and set the water inlet component on the top layer. Harvest plants regularly and in a timely manner during operation. Check indicators regularly.

[0043] According to the COD determination experiment national standard method (HJ828-2017), the average COD concentration of the system influent is 225.6mg / l, and the average COD concentration of the treated water flowing out of the collection pipeline is 93.4mg / l. Average removal rate: 58.6%.

[0044] According to the ...

Abstract

The invention discloses a deep treatment system of wastewater, comprising: a tank arranged in a filler component; dirt-absorbing plants planted on the filler component; an inflow component arranged atthe upper end of the filler component; a collection pipeline arranged at the bottom of the tank and used to collect treated water. The filler component comprises: a filter filler layer allowing plantgrowth, a gravel contact oxidizing filler layer arranged below the filter filler layer, and a support and drainage filler layer arranged below the filter filler layer. The three treatment modes, dirt-absorbing plant absorption, filler filtering and bio-contact oxidization, supplement each other, overall filtering effect is improved, the treatment effect is far better that that under the nationalgrade I standard A, close to the standard for five types of water; operational energy consumption is low, and operation is automated and stable.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an advanced sewage treatment system. Background technique [0002] With the gradual improvement of my country's sewage discharge standards, various sewage stations and factories are involved in the upgrading of advanced treatment standards. In particular, the direct discharge of rural sewage into the environment requires a complete and advanced treatment process and more convenient management and operation. [0003] The process of ordinary rural sewage is mostly manual system or integrated treatment equipment. However, the shortcomings of integrated equipment, such as high energy consumption and the need for special personnel to operate, are gradually exposed and gradually abandoned by people. Ordinary artificial systems cannot continue to operate well due to reasons such as blockage and seasonal alternation. The market needs an advanced treatment system with excellent sewage t...
