Black odoriferous water treatment method

Abstract

The invention discloses a black odoriferous water treatment method. The black odoriferous water treatment method comprises the following steps that exogenous solid-liquid waste is prevented from entering a polluted black odoriferous water body, and solid waste in the water body is preliminarily removed in a manual or mechanical salvage mode; after the solid waste residual body is removed and the exogenous solid-liquid waste is blocked, an activation composition is put in the black odoriferous water; the activation composition is prepared from silicon dioxide, titanium dioxide, activated carbon and iron powder; then a curing agent is put in the black odoriferous water body. The black odoriferous water treatment method can effectively improve the visual effect of the water body, improves the water transparency while remarkably reducing odoriferous substrates of the water body, improves dissolved oxygen level of the water body and improves the water body and a local micro-environment of surficial sediments. A corresponding product is expected to play a good treatment effect on removal of local phytogenic water body black odoriferous substances of rivers and lakes.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment and relates to a treatment method for black and odorous water. Background technique [0002] Landscape water bodies such as rivers are an important part of urban human settlements. However, due to their characteristics of easy pollution, small water environment capacity, and poor self-purification ability of water bodies, they can easily become the recipients of domestic sewage, rainwater, and garbage for residents, resulting in The massive consumption of dissolved oxygen in the water body has caused the water body to be in a black and odorous state due to the lack of oxygen, causing the entire ecosystem to be in crisis. Black and smelly urban rivers have become a common pollution problem in many large and medium-sized cities in my country. Black and smelly rivers are a common phenomenon in urban river networks in my country, seriously affecting residents' lives, city image and ecological...

Problems solved by technology

[0004] The existing treatment methods are generally physical methods, chemical methods and biological methods, but physical methods have high investment costs and slow results, while chemical methods have high cost of use and are likely to cause secondary pollution of water bodies. Biological methods are used in the treatment of black and odorous rivers. It is widely used in artificial wetland treatment, aquatic plant restoration, bioremediation, etc., but the biological method has the problem of slow processing speed.
