Embodiment Construction

[0027] In order to better understand the present invention, the technical scheme of the present invention will be further described below in conjunction with embodiment and accompanying drawing (as figure 1 , 2 shown).

[0028] Such as figure 1 Shown, a kind of method utilizing middle-term rainwater to restore black and smelly water body is characterized in that it comprises the following steps:

[0029] a. Rainwater runoff collection: collect rainwater runoff and enter the rainwater initial waste flow device;

[0030] b. Separation of rainwater: The initial rainwater discarding device first separates the initial rainwater and then discharges it (because the initial rainwater pollution is relatively serious and the amount is small, it is separated and discharged into the sewage pipe), and then collects the mid-term rainwater (because the mid-term rainwater is relatively clean, abundant water);

[0031] c. Reoxygenation treatment: the collected mid-term rainwater enters the...

Abstract

The invention belongs to the technical field of environment construction and protection and particularly relates to a method for restoring a black foul water body with medium-term rainwater. The method for restoring the black foul water body with the medium-term rainwater is characterized by comprising the following steps: a, collecting rainfall runoff: collecting rainfall runoff, and entering aninitial rainwater removal device; b, separating rainwater: firstly separating and then discharging the initial rainwater through the initial rainwater removal device, and then collecting the medium-term rainwater; c, reaerating: collecting the medium-term rainwater, entering a reaeration zone for reaerating; d, regulating through microorganisms: firstly configuring cobblestones and a biofilm colonization material in a water body of a contact area of the medium-term rainwater and the black foul water, and then inoculating an EM strain. The restoration of the black foul water body and the utilization of rainwater are combined to achieve the effects that the phenomenon of the black foul water body is improved, the resource of the medium-term rainwater is reasonably used, and the dissolved oxygen in the water body is increased.

Description

technical field [0001] The invention belongs to the technical field of environment construction and protection, and in particular relates to a method for repairing black and odorous water bodies by using medium-term rainwater. Background technique [0002] The rapid development of cities has caused water bodies to absorb more pollution than their self-purification capacity, and a large number of lakes and rivers have become black and smelly water bodies. One of the main reasons for the formation of black and odorous water bodies is that a large amount of dissolved oxygen is consumed and insufficient reoxygenation leads to a vicious cycle, and pollutants are not fully degraded. When the content of organic pollutants in the water body is too high, under the action of aerobic microorganisms, the decomposition of organic matter will consume a large amount of oxygen in the water, turning the water body into an anoxic or anaerobic state. Under anoxic and anaerobic conditions, met...
