Method for purifying solid waste in sea cucumber factory-like seedling protecting-cultivating pool by utilization of clam worms

Abstract

The invention discloses a method for purifying solid waste in a sea cucumber factory-like seedling protecting-cultivating pool by utilization of clam worms. The method is characterized by including the following steps: a substrate is laid in the sea cucumber factory-like seedling protecting-cultivating pool, the substrate is fine sand with the diameter of 0.1mm-1.0mm, and the thickness of the laying is 10-20cm; clam worm offspring seeds with specification of 1-3cm / one seed are put in the substrate; compound microorganisms are inoculated in the cultivating pool and effective microorganism (EM) bacteria in sea water, the cell concentration is that the number of beneficial microorganisms contained per milliliter is larger than or equal to one billion, and the inoculation density is 5pmm; at intervals of 1-3 weeks, the ammonia nitrogen density of the water body in the cultivating pool is measured, if the ammonia nitrogen density is larger than 0.1mg / L, compound microorganisms are inoculated in the whole cultivating pool by even splashing in a scooping mode, and the inoculation density is 3-10ppm; every mouth, the ammonia nitrogen density of interstitial water in the fine sand at the bottom of the cultivating pool is measured, if the ammonia nitrogen density of the interstitial water is larger than 1mg / L, water in the pool is drained, the pool is exposed, and the substrate in the pool is exposed for 5-7 days in a dried mode; and the clam worms are harvested by utilization of labor digging and catching.

Description

technical field [0001] The invention relates to a method for cleaning sea cucumber seedling cultivation ponds, in particular to a method for purifying solid waste in sea cucumber industrial seedling cultivation ponds by using clamworms. Background technique [0002] Sea cucumber is known as one of the eight treasures of seafood. Because it is rich in various amino acids, vitamins, and trace elements, sea cucumber has attracted widespread attention from consumers for its unique nutritional and medicinal values. In recent years, my country's sea cucumber industry has developed rapidly. The artificial breeding of sea cucumbers is the basis for the rapid development of the industry. At present, industrial artificial seedlings are the main method of sea cucumber seed production, accounting for more than 80% of seed production. The preservation of seedlings is the main link in the whole artificial breeding of sea cucumbers. After about a week of planktonic life, sea cucumber lar...

Problems solved by technology

Especially in winter, it is necessary to provide a good growth environment for sea cucumbers by heating up seawater, which also consumes a lot of energy and production costs

In order to save costs, most of the sea cucumber nursery ponds do not change water in time during the wintering period, and the water exchange in the nursery ponds is not smooth.

Especially in recent years, the density of sea cucumber seedlings and seedling preservation has become higher and higher, and a large amount of bait is required to be fed, and the water cannot be changed in time, which has gradually caused a large amount of residual bait and feces at the bottom of the seedling preservation pond, and a large increase in the concentration of ammonia nitrogen and hydrogen sulfide. , resulting in a decline in the water quality in the seedling pool, which in turn leads to a decrease in seedling resistance, frequent occurrence of diseases, and a large number of seedling deaths
