Embodiment 1

[0095] An ecological purification system for lobster breeding tail water, comprising five subsystems: an irrigation and drainage system 1, a water level regulation system 2, a water quality monitoring system 3, a lobster breeding system 4 and a paddy field planting system 5.

[0096] The irrigation and drainage system 1 is connected to the lobster culture system 4 , the outlet of the lobster culture system 4 is connected to the paddy field planting system 5 , and the water level regulation system 2 and the water quality monitoring system 3 are connected to the lobster culture system 4 .

[0097] The number of control weirs, water level gauges and water quality monitors of the water quality monitoring system in the above-mentioned water level regulation system is 4, which is determined based on the number of culture units included in the lobster culture system, and is only used here for illustration. not for limitation.

[0098] The irrigation and drainage system 1 includes an ...

Embodiment 2

[0140] Others are the same as embodiment 1.

[0141] The water quality monitor 3-1 of the water quality monitoring system 3 monitors pH, DO, COD, NH in the water quality 3 -N, TN, and TP are monitored online, and the detection data are shown in Table 1:

[0142] Table 5 embodiment 2 high-density cultivation unit 4-1 water quality monitoring situation

[0143]

[0144] It is determined that the COD concentration exceeds the standard and cannot directly enter the medium-density breeding unit 4-2. Open the water inlet 5-1 of the paddy field buffer system 5 to allow the substandard water to enter the paddy field buffer system 5, and the water passes through the furrow 5- of the paddy field buffer system 5. 2 for irrigation, after the planting unit 5-3 of the paddy field buffer system 5 purifies the buffer, and then enters the lobster culture system 4 again.

Embodiment 3

[0146] Others are the same as embodiment 1.

[0147] The monitoring situation of water quality in density culture unit 4-2 in table 6 embodiment 3

[0148]

[0149] After determination, COD, NH 3 -N exceeds the standard and cannot directly enter the medium-density breeding unit 4-3, open the water inlet 5-1 of the paddy field buffer system 5 to make the substandard water enter the paddy field buffer system 5, and the water body is irrigated through the furrow 5-2 of the paddy field buffer system 5 , the planting unit 5-3 of the paddy field buffer system 5 is purified and buffered, and then enters the lobster culture system 4 again.

Abstract

The invention discloses a lobster breeding tail water ecological purification system and an operation method. The system comprises an irrigation and drainage system (1), a water level adjusting system (2), a water quality monitoring system (3), a lobster breeding system (4) and a rice field planting system (5). The irrigation and drainage system (1) conveys a water source to the lobster breeding system (4), the water quality monitoring system (3) detects the water quality of breeding units, the water level adjusting system (2) adjusts the water level and dispatches the water quantity according to the pollutant threshold value of each breeding unit, if the pollutant concentration exceeds the standard, t water enters the rice field planting system (5) for tail water ecological treatment, and finally aquaculture water circulation is achieved. According to the lobster breeding tail water ecological purification system, a shrimp-rice-fish three-in-one ecological breeding purification system is constructed, a water quality-water quantity-water circulation scientific, intelligent and accurate regulation and control system is formed, and the prominent problems of substandard discharge of aquaculture tail water, low breeding yield, poor quality, high bait dosage, non-sustainability and the like are solved.

Description

technical field [0001] The invention belongs to the fields of green ecology, water body purification and recycling environmental protection, and in particular relates to an ecological purification system and operation method of lobster breeding tail water. Background technique [0002] With the rapid development of the aquaculture industry, lobster has been researched on artificial breeding in most areas. Traditional lobster farming has a high demand for fresh water quality, and the concentration of pollutants in the tail water is extremely high, which is likely to cause agricultural non-point source pollution. Therefore, in order to solve the above problems, advanced, scientific and intelligent aquaculture water treatment and circulation aquaculture methods must be adopted to solve a series of problems caused by the current aquaculture wastewater.
