Solid composite biological preparation for in-situ repairing and treatment on black and odorous water body bottom mud and preparation method of solid composite biological preparation

Abstract

The invention discloses a solid composite biological preparation for in-situ repairing and treatment on black and odorous water body bottom mud and a preparation method of the solid composite biological preparation. The solid composite biological preparation is characterized by comprising the following materials in parts by weight: 15-30 parts of a biological composite enzyme, 15-30 parts of a composite microorganism bacterial liquid, 10-15 parts of a microorganism growth promoter, 1-5 parts of a protection agent and 20-40 parts of dry powder aids. By adopting the solid composite biological preparation disclosed by the invention, due to physical, chemical and biological functions of the components upon bottom mud, the bottom mud can be greatly reduced, and the problem of black and odorouswater bodies can be remarkably alleviated; meanwhile, in-situ biological repairing and degradation functions can be activated and intensified, the self cleaning capability of the bottom mud is improved, and the bottom mud can be further reduced. The solid composite biological preparation has the advantages of being wide in raw material source, high in treatment efficiency, good in adaptability, low in cost, low in production and operation cost, and the like.

Description

technical field [0001] The invention relates to the field of environmental pollution control, in particular to a solid composite biological preparation for in-situ repair and treatment of black and odorous water bottom mud and a preparation method thereof. Background technique [0002] With the continuous development of my country's economy, the continuous improvement of the level of industrialization, the rapid advancement of urbanization and the continuous improvement of people's living standards, the production of domestic sewage and industrial sewage has increased year by year. Due to the lack of people's environmental awareness and the lag of water pollution control facilities, a large number of Sewage is directly discharged into urban water bodies, causing black and odorous phenomena in the urban water ecological environment. [0003] The most direct reason for the black and odorous phenomenon in the water body is that there are too many organic pollutants, and the oxyg...

Problems solved by technology

[0007] In order to eliminate black and odorous water bodies, in addition to controlling external pollution, it is also necessary to treat and repair the sediment. At present, the sediment treatment and restoration technologies mainly include ex-situ restoration and in-situ restoration, and the ex-situ restoration technology mainly refers to dredging technology and The post-dredging treatment technology of sediment and the heterotopic restoration method of sediment are limited due to the large amount of engineering, high cost, difficulty in controlling the dredging depth, and the difficulty of subsequent sludge treatment.

In-situ remediation mainly includes solidification / stabilization, chemical remediation, bioremediation and other methods. Solidification / stabilization and chemical remediation have problems such as high cost of chemicals and re-release of pollutants. For this reason, bioremediation is widely favored. Restoration agents have problems such as easy loss, large dosage, low efficiency, and high cost. Therefore, it is urgent to develop an in-situ bioremediation agent for sediment with high processing efficiency, strong adaptability, and low price.
