Embodiment Construction

[0025] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0026] The detection method of a kind of breeding pond sediment pollution coefficient of the present invention comprises the following detection steps:

[0027] 1. Design of sediment collector

[0028] The body of the sediment collector is designed as a hollow frustum-shaped glass container, and the container is opened on the upper and lower surface of the table body, which can prevent the sediment sinking into the collector from being lost to the water body due to the influence of factors such as water flow agitation. The inner diameter of the upper bottom surface of the container is 24cm, the inner diameter of the lower bottom surface is 46cm, and the height is 20cm. Three holes 3 are evenly arranged on the side wall near the upper bottom of the collector body 4, for tying a rope 2, and a foam float 1 is tied at the top of the rope, thereby indicati...

Abstract

The invention relates to a method for detecting the pollutant production coefficient of deposit in a cultivation pond. The method comprises the following detection steps of: 1, a deposit collector is a hollow platform container; 2, placing and salvaging the deposit collector, namely, placing the deposit collector in the cultivation pond, salvaging the deposit collector when fishes are captured, and calculating the deposit amount of the whole pond according to the pond area; 3, estimating the deposit mass in the pond, namely, estimating the deposit mass in the deposit collector by using a difference method; 4, determining each pollution index concentration in the deposit, namely, determining the moisture content of the deposit and the major pollution indexes in the deposit; and 5, detecting according to a deposit pollutant production coefficient detection formula. The detection method of the invention is scientific and easy and can accurately detect the pollutant production coefficient of the deposit in the fish cultivation pond and estimate the pollution load of pond cultivation on the pond; and moreover, the detection of the pollutant production coefficient of the deposit in the pond is of great importance to the scientific control on the water quality of the pond, to the estimation of the pollution level of pond cultivation on the pond and the environment outside the pond, and the like.

Description

technical field [0001] The invention relates to a detection method for sediment pollution production coefficient of aquaculture ponds, specifically for detecting the sediment pollution production coefficient of fish aquaculture ponds and estimating the pollution load of pond aquaculture on itself, belonging to the technical field of fishery ecological environment monitoring. Background technique [0002] Since the reform and opening up, my country has implemented the fishery development policy of "mainly raising fish". In 2006, my country's freshwater aquaculture output reached 21.4831 million tons, accounting for 59.78% of the total aquaculture output (35.9395 million tons); among them, the freshwater pond aquaculture output and area were 14.9451 million tons and 25.3105 million hectares, accounting for freshwater aquaculture output and 25.3105 million hectares respectively. 69.57% and 42.06% of the area, freshwater pond aquaculture contributes significantly to freshwater aq...
