preparation example Construction

[0022] The embodiment of the present invention also provides a preparation method of a microbial rapid clarifier for black and odorous water, which is used to prepare the above rapid clarifier, comprising the following steps:

[0023] Prepare the polyaluminum chloride aqueous solution of A liquid, the native microbial bacterial liquid of B liquid and the trace element liquid of C liquid respectively;

[0024] Take liquid A, liquid B and liquid C according to 0.5-10 parts by weight of liquid A, 1-3 parts by weight of liquid B and 0.1-1 part by weight of liquid C. When preparing, add liquid C to liquid B first, stir and mix well, After 30 minutes, add liquid A, and after standing for 1 hour, the microbial rapid clarifier for black and odorous water can be prepared.

[0025] In the above preparation method, the polyaluminum chloride aqueous solution of liquid A is composed of 1-10 parts by weight of polyaluminum chloride and 500-1000 parts by weight of water;

[0026] The trace ...

Embodiment 1

[0034] The present embodiment provides a microbial fast clarifier for black and odorous water. The preparation method of the clarifier is as follows: according to the weight ratio of 10 parts by weight of liquid A, 3 parts by weight of liquid B, and 1 part by weight of liquid C, the rapid clear liquid.

[0035] Wherein, liquid A is prepared from 10 parts by weight of PAC (polyaluminum chloride) and 1000 parts by weight of water.

[0036]Liquid B is composed of indigenous microbial bacterial liquid. Production method: select the sediment to be treated in the river, insert it into the indigenous microorganism enrichment medium, and culture it on a shaking table at a speed of 180r / min at 38°C for 3 days to prepare the indigenous microorganism enrichment solution. The enriched liquid of indigenous microorganisms was added to the isolation and purification medium of indigenous microorganisms, and cultured on a shaking table at 35°C at a speed of 160r / min for 10 days to obtain puri...

Abstract

The invention discloses a rapid microbial clarifying agent for a black and odorous water body, belonging to the field of sewage bio-treatment. The rapid clarifying agent comprises the following components in parts by weight: 0.5-10 parts of liquid A, 1-3 parts of liquid B, and 0.1-1 part of liquid C, wherein the liquid A is a polymerized aluminum chloride water solution; the liquid B is an indigenous microorganism bacteria solution; and the liquid C is a microelement solution. According to the rapid clarifying agent, the strain, namely the liquid B, for degrading the black and odorous water body can be separated and screened by taking bottom mud of a river way as a raw material. The liquid A and the liquid C are added to prepare the rapid microbial clarifying agent. After the rapid microbial clarifying agent is added in the black and odorous water body, the black and odorous water body can be clarified within 4 hours to achieve comfortable feeling.

Description

technical field [0001] The invention belongs to the field of microbial treatment of sewage, and in particular relates to a microbial rapid clarifier for treatment of black and odorous water bodies in rivers and a preparation method thereof. Background technique [0002] With the release of the "Guidelines for the Work of Urban Black and Odorous Water Bodies", certain standards have been established for the treatment of black and odorous water bodies. Generally, physical, chemical and biological methods can be used to control point sources, non-point sources and internal sources. The biological method is the most economical of all methods. The disadvantage of the biological method is the slow processing speed. In view of the above shortcomings, the use of microbial rapid clarifier can quickly clarify the black and odorous water within 4 hours to achieve comfortable transparency. Patent No. 201010610486.2 is an invention patent, which provides a method for microbial treatme...
