Later, various medicines were used in the process of water control, although there was no alum (KAl(SO 4 ) 2 ) is so obvious, but there will always be various drug residues left after treatment. This kind of residue is not easy to detect. After continuous accumulation, its potential harm is even higher. With the improvement of people's environmental awareness, the use of drug treatment is also gradually boycotted by people
Today, when the original ecology is emphasized, various so-called ecological management methods have emerged, such as using biological enzymes to catalyze the reaction speed of a certain substance, which can indeed achieve good results under certain conditions, but the specificity of enzymes ( That is, one kind of enzyme only catalyzes one type of substance) so that various enzymes need to be used in the treatment of sewage. The essence of the enzyme is protein or RNA, which is easy to lose its activity. Its instability is easy to cause another form of pollution. Enzyme Other ingredients added in the preparation will also cause certain drug residues

Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] Such as figure 1 Shown, the sewage treatment system of the pit pond of present embodiment comprises pit pond 2, mixing tank 1, water inlet pipe 62, outlet pipe A 61, outlet pipe B 72, return pipe 71, more than one mud pump 4 and two Mobile Electric Mixer 3 above. The mixing pool 1 is located near the pit pond 2 and not lower than the pit pond 2, its area is at least 30% of the pit pond 2, and its depth is 0.6-1.0 meters. Preferably, the water level of the stirring pond is the best 3-4 meters above the pit pond level; the stirring pond 1 area is the same as the pit pond 2, and the treatment period is short, and the smaller the area, the longer the treatment period, and the minimum It is less than 30% of the area of the pond; the soil depth stirred by the mobile electric mixer 3 in the mixing tank is best at 20-25cm. The mud pump 4 is...

The invention discloses the sewage treatment system and the treatment method of a pit pond. The system comprises the pit pond, a stirring pool, the water inlet pipe and the water outlet pipe B of thestirring pool, the water outlet pipe A and the water return pipe of the pit pond, more than one muddy water pumps fixed to a pit pond bottom surface and more than one mobile electric stirring machinesin the pit pond and the stirring pool. A stirring pool area is not less than 30% of a pit pond area. The method comprises the following steps of deeply ploughing soil in the bottom surface of the stirring pool, carrying out air drying, and discharging fully-mixed muddy water in the pit pond into the stirring pool; stirring the muddy water in the stirring pool, wherein water in the stirring pool is automatically flown into the pit pond; after uninterrupted stirring 24 hours for 7 to 15 days, discharging all the water in the stirring pool to the pit pond; and after mud in the stirring pool is semi-dried, deeply ploughing the bottom soil, carrying out air drying, and repeating the above operation. In the invention, any forms of medicaments are not added, the mud and the water are treated atthe same time and sewage is used to treat pollution; and eutrophic elements in sludge are fully used, wastes are turned into treasure, investment is low and an effect is quick.
Description
technical field [0001] The invention relates to a sewage treatment system and a treatment method for pits and ponds. Background technique [0002] The formation of pond pollution is generally caused by the excessive discharge of domestic sewage or other reasons resulting in excess eutrophication, the disappearance of dissolved oxygen in water, and thus the loss of ecological balance. In ponds, water often flows very slowly, and there is usually a large amount of sludge at the bottom. There are a lot of decomposed or undecomposed nutrients in this sewage and sludge. [0003] Traditional sewage treatment methods are generally separation and precipitation, using alum (KAl(SO 4 ) 2 ) is the most commonly used method among the early folk, and the effect of this method is more obvious, but the Al produced after the alum dissolves in water 3+ It is very harmful to the human body and is now banned from use. Later, various medicines were used in the process of water control, alth...
