specific Embodiment approach 1

[0008] Specific embodiment 1: In this embodiment, bio-intensive restoration of landscape water is carried out according to the following steps: a. Screening of functional bacteria: screening of nitrous acid oxidizing bacteria, ammonia oxidizing bacteria and phosphorus-accumulating bacteria from the polluted water body to be repaired; b. Domestication of functional bacteria : Nitrite oxidizing bacteria, ammonia oxidizing bacteria and phosphorus accumulating bacteria are cultivated with common beef extract peptone medium respectively, and then cultivated with domestication medium; Ammonia oxidizing bacteria and phosphorus accumulating bacteria were mixed according to the quantity ratio of 1:2:1 and expanded culture, and the number of mixed functional bacteria was 10 8 pieces / mL hang on the filter bed matrix; d. Purification: dynamic or static purification, water can be discharged; wherein the domestication medium in step b is to gradually replace the beef extract peptone medium w...

specific Embodiment approach 2

[0017] Specific embodiment two: this embodiment is described in conjunction with Fig. 1, and the difference between this embodiment and specific embodiment one is: in step c, the filter bed matrix is ​​from top to bottom a sand layer 1 with a thickness of 4 to 5 cm, and a thickness of 25 to 27 cm. The zeolite layer 2 and the slag layer 3 with a thickness of 5-6 cm are composed, and a partition 4 is vertically arranged in the middle of the filter bed, and the partition 4 penetrates the sand layer 1 and the zeolite layer 2 . Other steps and parameters are the same as those in Embodiment 1.

[0018] The main components of slag are quartz, siderite, calcium oxide and calcite, which have strong adsorption properties for phosphate. The slag passivates and precipitates phosphate through chemical combination, so as to achieve the purpose of removing phosphate pollutants in landscape water.

[0019] Sand prevents bulky solid contaminants from clogging the filter bed.

specific Embodiment approach 3

[0021] Specific embodiment three: the difference between this embodiment and specific embodiment two is: the particle diameter of sand in the step c is 0.5~1mm, and the particle diameter of slag is 5~10mm, and zeolite layer 2 is 2~4mm by particle diameter and 4-8mm monoclinic zeolite is mixed in a volume ratio of 1:1. Other steps and parameters are the same as those in Embodiment 2.

[0022] The zeolite in this embodiment is a monoclinic zeolite with a hardness of 3.5 to 4 and a specific gravity of 2.2. Since the zeolite used in this embodiment is made of SiO 2 and Al 2 o 3 Tetrahedral units are staggered to form a spatial network, and the crystal structure is open, so it contains many channels and cavities (3-11 Ȧ) with uneven sizes.

[0023] The zeolite in this embodiment has good thermal stability, acid resistance, dehydratability, electrical conductivity, catalytic cracking property of chemical reaction, radiation resistance and low bulk density, porosity and other cha...

Abstract

A bioaugmentation method for restoring landscape water relates to a way of restoring water body. The method solves the problem of bad effect to aquatic ecology caused by chemicals usage in existing landscape water body restoration to add other pollutions to water, and also solves the problems of high cost, time and energy consuming and short maintaining time by using physical method and the problems of slow speed of dirt removal and endogenous pollution by using biological and ecological methods. The method is that: a. screening of functional bacterial; b. acclimatization of functional bacterial; c. enlarging cultivation and covering of functional bacterial; d. purification. After the steps, the water can be reused. The invention of restoration way for restoring landscape water is without adding any chemical and micro-biological agents, which not only saves the cost of water restoration, but also does not affect aquatic ecosystem and add other pollutions. The invention of landscape water restoration method has low operation cost, time saving and energy conservation, fast speed for dirt removal, and can restrain the release of endogenous pollution, block and weaken exogenous pollution, be recyclable and maintain water quality for long time.

Description

technical field [0001] The invention relates to a method for restoring a water body. Background technique [0002] The landscape water body can beautify the environment and adjust the ecological climate of the micro-environment, but because the water in it is in a static or closed slow-flow state with poor fluidity, its own purification ability is poor and the pollution degree is high. [0003] In order to restore the polluted landscape water body, the technologies currently adopted in the world include chemical methods, physical methods and biological-ecological methods. Chemical methods: adding chemical agents to kill algae, adding iron salts to promote the precipitation of phosphorus, adding lime to denitrify, etc.; although chemical methods can produce water purification effects in a short period of time, they will have adverse effects on the aquatic ecology in the later stage, and increase other water quality. pollution load. Physical methods: dredging bottom mud, mec...
