Fully automatic filter is mainly used for urban community landscape water purification

The automatic filter ecological purification base can utilize natural lake ponds, eliminating the civil construction and realizing unpowered or micro-powered sewage treatment. At present, fully automatic filter technology has been applied in more than 80 countries. In China, there are many applications in Guangdong, which are mainly used for the purification of landscape water bodies in urban communities.
How to realize the harmless treatment and resource utilization of landscape water---
1. Powered underground integrated treatment technology At present, the power-embedded integrated treatment technology can be divided into biological contact oxidation method, SBR, A/O and A2/O according to the process. The principle of the commonly used A/O treatment technology is that in the anoxic tank, the microorganisms reduce the nitrate nitrogen and nitrite nitrogen in the sewage to gaseous nitrogen, and at the same time decompose the refractory macromolecular organic matter into small molecular easily degradable substances. It has the functions of denitrifying, hydrolyzing and degrading some organic substances; in the aerobic tank, most of the organic matter is treated by microorganisms, and enters the secondary sedimentation tank for separation of muddy water, which is discharged after being disinfected.

The A/O process degrades organic matter at the same time as denitrification, so that the oxygen demand is greatly reduced, and it is an energy-saving biological treatment technology. In order to maintain a high nitrification rate, the reaction residence time is longer than that of the conventional activated sludge process, the sludge settling performance is good, the sludge growth rate is low, the excess sludge amount is small, and the settling performance is good.
Hanshan Community in Tangqiao Town of Zhangjiagang City, Qianxi Community in Yangshe Town and Yuanfeng Community in Jingang Town all use powered buried sewage treatment system, of which Hanshan Community of Tangqiao Town invested 350,000 yuan and treated 240 tons of sewage per day. Jingang Town Yuanfeng Community invested 500,000 yuan, with a daily sewage treatment capacity of 480 tons, and is currently in good operating condition.
2, domestic sewage purification biogas tank technology small domestic sewage purification biogas tank application of normal temperature anaerobic fermentation technology, in accordance with the principle of "multi-stage self-flow, step-by-step degradation", establish a class I anaerobic fermentation - a new level II facultative digestion filter Device. It consists of anaerobic fermentation, facultative digestion filtration, sewage reflux and packing. Most of the organic matter in domestic sewage is biogas produced after anaerobic fermentation. The fermented sewage enters the facultative digestion filter tank, and some undecomposed organic matter is further degraded. Part of the precipitated organic matter and activated sludge are refluxed into the anaerobic fermentation tank to improve the effect of anaerobic fermentation, which will achieve the purpose of purification treatment.
The domestic sewage purification biogas tank is a small decentralized sewage treatment device, which has the characteristics of low investment, good effect, and no energy support for operation. At present, the technology has been widely used in Lishui, Donghai and other places, and the results are more significant.
3, automatic filter landscape water treatment technology automatic filter is a kind of water treatment equipment invented by Boyuan Jinkai Filtration Equipment (Beijing) Co., Ltd., belonging to an artificial polymer inert ecological medium (filler).

The main features of the fully automatic filter are:

1 Large specific surface area, which can provide a huge biological attachment surface for the growth and reproduction of microorganisms and beneficial algae in water.

2 The pore structure suitable for living organisms provides a good living environment for autotrophic organisms (such as algae) and improves the efficiency of water purification.

3 No filler bracket is needed, the lower end is in the shape of a pocket, and the heavy object can be loaded, and the upper part is suspended in the water body like water plants, so that the dissolved organic matter and dissolved oxygen in the water body are in contact with the biofilm to the maximum extent, and the degradation rate of the pollutant is improved.

4 Unique double-sided structure design, the product is more dense and darker on one side, while the other side is looser and lighter in color, forming an ideal “aerobic-facultative-anaerobic” microenvironment on its cross section. Efficient nitrogen and phosphorus removal.
The automatic filter ecological purification base can utilize natural lake ponds, eliminating the civil construction and realizing unpowered or micro-powered sewage treatment. At present, fully automatic filter technology has been applied in more than 80 countries. In China, there are many applications in Guangdong, which are mainly used for the purification of landscape water bodies in urban communities. After being adopted in the ecological restoration of the water body of the Diaoyutai State Guesthouse in Beijing, preliminary results have also been achieved.
