Problems solved by technology

Although these methods can treat black and odorous water bodies to a certain extent, there are shortcomings or deficiencies such as unsatisfactory treatment effects, high costs, secondary pollution, and difficulty in ensuring long-term treatment effects.
[0004] In addition, the sediment of the black and odorous water body contains a large amount of pollutants, which is the endogenous pollution of the black and odorous water body. If the black and odorous water body is to be treated, the sediment must also be dredged. Improper use will cause huge damage to the ecological environment
The water body sediment after dredging is usually piled up in the mud storage yard as solid waste, which not only takes up a lot of space, but also easily causes secondary environmental pollution
At the same time, after the aquatic plants in the black and odorous water body are mature, if they are not treated, they will also become endogenous pollution of the water body

Embodiment

[0032] see figure 1 , the present embodiment provides a system for controlling black and odorous water bodies. At first, select a black and odorous water body (total nitrogen: 142mg / L, total phosphorus: 22mg / L, COD Cr : 560mg / L) ponds, set up a biochar filter 1 in the direction of water inflow, harvest aquatic plants 3 in the mature stage, and then dry and pulverize them separately with the bottom mud of the water body and mix them in a mass ratio of 4:1 , high-temperature pyrolysis under anoxic conditions to obtain biochar, and then activate the biochar to obtain activated biochar 4; part of the obtained activated biochar 4 is used to fill the biochar filter 1 in the direction of water, and part of it is thrown into the water body to settle to the bottom of the water body The bottom matrix 2 is formed in the mud.

[0033] Wherein the preparation process of activated biochar 4 is:

[0034] (1) drying the harvested aquatic plants 3 and the water body bottom mud after dredging...

Abstract

The invention discloses a system for treating black stinking water. The system comprises an incoming water direction biological carbon filter, a water bottom substrate and aquatic plants, wherein the incoming water direction biological carbon filter is arranged in the incoming water direction of the system and is filled with activated biological carbon; the water bottom substrate is composed of water body bottom mud and activated charcoal; and the aquatic plants are planted on the water bottom substrate. The method for preparing the activated charcoal comprises the following steps: harvesting the mature aquatic plants, and sequentially drying and grinding; sequentially drying and grinding the water body bottom mud subjected to desilting; fully mixing the ground aquatic plants and water body bottom mud according to a mass ratio of (3-5):1, thereby obtaining a mixture; and performing high-temperature pyrolysis on the mixture under anoxic conditions so as to obtain the charcoal, and performing acid activation, thereby obtaining the activated charcoal.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a system for controlling black and odorous water bodies. Background technique [0002] With the development of society and industry, the massive discharge of domestic sewage and industrial wastewater has caused water bodies such as rivers, lakes and seas to be polluted and become eutrophic water bodies. A large amount of organic pollutants, ammonia nitrogen, etc. accumulate in the sediment of the water body, and anaerobic reaction produces stench. At present, there are a large number of black and odorous water bodies in our country, which urgently need to be treated. [0003] For the treatment of black and odorous water bodies, the main methods are intercepting sewage, dredging, adding microbial agents, changing water, and planting aquatic plants. Although these methods can control black and odorous water bodies to a certain extent, there are shortcomings or deficiencies such as uns...
